Merry Christmas and a Happy New Year!
Another year have passed, and I am still alive! \o/
So towards the later half of this year I have started to try and learn Unity. It has been quite a nice experience so far, still so much to learn though. The plan is to make some kind of logic puzzle game for the mobile/tablet market.
Have also been experimenting with some VR platforms like Vive and Daydream, which have been really fun. Can’t show much due to secrecy/nda/etc..
The beer-brewing is going fine, gonna put the Christmas beer to the test tomorrow.
Until next time!
Time for my yearly blogpost again… Another year as a webdeveloper have passed. Still at North Kingdom, over 10 years now, still liking it.
Have had some fun projects this year as well, still trying to focus mostly on canvas and 3d/webgl(and staying away from css/html). Some smaller things with VR, feels like many want to ride the hype, but not really sure how to climb the unicorn.. See how that will pan out.
We have also gotten to a point where it is about as complicated to “compile” a fucking website as it was to compile a whole operating system 15 years ago… Good work webdev-community!! (:
On a personal level, have had another(third) kid this year, was a girl this time! \o/
Have joined a local hobby beer-brewery.. gotta have a hobby!
So Cheers! Merry Christmas and a Happy New Year!
Almost forgot my yearly xmas-blogpost this year.. But here I am!
So Merry Christmas and a Happy New Year, once again!
Have nothing nice or wise to say about our “industry” this year, so I’ll keep it to myself.. ;)
Another year have almost passed by, time for my yearly blogpost…
The trend at work is no Flash at all this year, it have mostly moved over towards WebGL and Canvas, and I kinda enjoy it for the most part. Lately I have worked on a large project where we tried to experiment with what we could do in modern browsers on modern mobile devices, as everything is supposed to be “mobile” these days.
It was interesting for sure, and a learning process. And also a lot of work, iterating and testing.
Finally time to unplug for a couple of weeks and celebrate christmas.
So, have a great holiday and see you in 2014!
It’s skeletal animation(skinning), the earlier MD2 format for example is vertex animation(morphTargets).
Here’s how you use it:
1. Drag and drop a *.md5mesh file.
2. Drag and drop a *.md5anim file.
3. Drag and drop a jpg/png for texture.
Any image containing ‘normal’ will be used as a normalMap, ‘bump’ as bumpMap, ‘specular’ as specularMap. None of these and it will be used as the diffuseMap. (this is for preview only and is not saved in the json)
Then save the file.
You can also tick “Lock rootbone” this locks the root bone to position 0,0,0 and the rotation to 0,0,0.
There is also an option to only export the animation data.
Also posted a fairly simple example of how to load a model and some animations, see here. Also shows how you could position other objects relative to the bones.
A small note about materials. I made it so every “mesh” in the *.md5mesh gets it’s own material index. And the idea is that you override the materials in the json-file with your own materials. The above example does that for example.
Three.js does currently not support blending of animations(like interpolating between animations for smooth transitions), hopefully someone will add that sometime in the future. Would be a great feature to have. :)
Edit (Feb 13 2014): Someone added basic support for blending a few months ago to three.js. Did a first test here, using the troll from the Hobbit-project.
There is currently some issues with the site, probably due to the recent server move. So no subpages can currently be accessed :/. Hopefully Jocke will fix it soon.. :)
Edit 2013-15-16: Seems to work again now, turns out I had to update the permalinks after the server move…
Time for my yearly tradition to at least show some sort of sign of life, usually around Xmas.
Have been home on ‘daddyleave’ with kid nr 2 since the beginning of July, so lots of playing with Lego(for real), changing filthy diapers, cleaning, and lately playing in the snow.
Also had a 5 month coding break. So lots of ideas/thoughts have piled up, so have done some small js/webgl experiments recently(even one with a winter/xmas theme).
Really looking forward to get back to work again after New Year. It’s really great with kids and all! But honestly.. some mornings it’s a bit like waking up at a mental institution, during a full scale riot.. :)
My blood presure must have gone up for sure… So it will be great to get back to the more ‘mature’ people in ad-industry with their sane, well timed deadlines, etc… :P
Have a nice holiday and a great 2013!
Been working with a really fun project earlier this spring. Thought I´d try to give some brief insight in to part of the development process here, and some of the fun we´ve been having.
It can be described as a mash-up between Google Maps and LEGO®, where you can build LEGO on top of Maps. It´s called “Build with Chrome”. Here’s a YouTube video explaining it more visually.
We start out with what we call the “Discovery phase”. This is basicly where each dicipline tries to see the biggest challenges with the project and start exploring different options/paths/etc. Anything goes..
I saw two big challenges here. The first one being the builder, like how do you make some 3d-tool simple enough so normal people can use it. The second thing was how do you display peoples builds, several at the time without hitting to big performance issues.
We started with the second challenge.
Having recently worked with particles, my mindset was set to that.. So my initial idea was to treat the LEGO bricks as particles or several particles makes up a brick, etc.. The idea is to use a sprite/particle of the smallest brick and so on. 1 vertex = 1 sprite. So this is not “real” 3d, but more isometric/ortographic, no perpective. Here´s the first test, so you can see what I mean:
(Small note. There is a bug with gl_PointCoord with certain older ati-drivers(like osx uses for example), where it flips the sprites vertically. Never bothered to fix a workaround, so if it looks weird for you, it´s probably that, and you should use the (flipped versions).)
Isometric 1 (flipped)
I wanted to get rotation in there. So we rendered out a png-sequence of a 90 degree spin, then based on the viewing angle we update the sprite texture. Here´s and example of that:
(Mousedown and drag left/right)
Isometric 2 (flipped)
This was sort off a long shot track. So at the same time Mikael Emtinger was working on the more classical real 3d approach. But with a twist. So he also saw the challenge in how to draw potentially lots of geomtery in a really a optimized way, or as few drawcalls as possible.
The idea is basicly to construct the geometry in the shader. So the “geometry” is basicly a cube that is defined as a uniform. Then the geometry is “built up” in the shader with an attribute stream, with sizes, offsets and colors being sent in.
He started out with a texture stream, but then converted to a attribute stream for compability-issues, but kept the idea of storing models in a bitmap, like using rgb-channel, pixel values for width, height, depth, x, y, z, colorindex, etc.
The pegs in this approach is done with “camera mapping”, basicly a high poly peg is rendered to an offscreen buffer at the current camera angle and then that is used as a repeated texture. And this is basicly what is used in the “explore” mode to display models.
There are drawbacks with each approach of course, but always good to have different directions. The client eventually wanted the real 3d approach.
Kind of a relief in retroperspective, not sure how we would have solved certain thing with the isometric approach.. ;)
So the next thing was to decide framework, since we had Micke onboard and he have developed Glow, we decided to go with that to be able to have an optimized render-pipeline since this is very much a single purpose thing. That is rendering LEGO bricks.
Still that needed much behind-the-scenes development to get to a point where we front-end-folks could make something nice with it.
So I started using my usual weapon of choice, Three.js, to prototype with, and by this time the other big challenge have been pushed on to my desk(#¤#!ers). The builder. I was a bit scared of this.. but it was just to “bite the bull” or whatever you say… ;)
So we entered what we call the “Definition phase”, the goal is to define what it is we should produce, functions, visuals, etc.
Started by trying to find inspiration in other similar tools, like voxel-editors, etc.. I wanted to find something really simple as the target audience here was normal people and not tech-savvy geeks. Saw something interesting in 3d-paint, a voxel tool, like you had a gridplane that you could move around, so it basicly became like drawing in 2d.
That was the first thing I tried.
The feeling of being able to “draw” bricks was kinda nice, but building something became quite weird.
So I tried with the more classical approach, that is more on par with the LEGO Digitial Designer, which is really nice, but it’s more advanced and more “cad” than what we were aiming for here.
How it works is that when you point the mouse to the top-surface, a invisible plane gets positioned on top of the brick and is sized and positioned depending on the target brick and the “in hand”-brick + rotation. So the ray hits that instead and you can position at any peg. Also made it auto-stack upwards.
Incremental version. Added preview pegs to the ghostbricks so you could more easily see where it would go.
One that tested autosaving with local storage.
A version with more bricks, updated dummy-gui, also thin bricks.
A version with real pegs added. Also trying to figure out how to deal with tall builds, hence the y-slider in the top-right corner.
Added the sloped bricks.
Test with a maps-texture. In animation and more..
Visual tweaks, trying to get the ADs/gfx people happy… I saw mission impossible 4 that night btw.. just sayin…
So now Micke had gotten to a point with his LEGO-version of Glow, dubbed GLego, that it was time for me to stop prototyping and build it “for real”. The production phase. Which basicly meant tearing everything down and start from scratch, using GLego instead of Three.
Might add that I had hard time explaining this to PMs, ADs, clients, etc… “But it´s working…, We´re almost there!” Anyway…
I got up to speed pretty quickly, Micke had done a great job, and I constantly bugged him for new features/fixes etc.
And here´s a first version of GLego-version that I showed:
GLego Builder 0
An incremental one with loads of fixes after feedback, etc.
GLego Builder 1
And the last one using my horrible dummy-gui. Added environment mapping and more.
GLego Builder 2
From there on it went in to the app-engine version, where a real gui was applied, bugfixes, small tweaks, changes and so on. And eventually it became what is on the live site.
This was LOADS of fun to work with and I´m quite alright with how it turned out, for once.
LEGO and WebGL in one project is like a real nerd-fiesta..
As always it´s a collaboration between many parties. We at North Kingdom. Agigen helped with both the backend and html/css-frontend. Mikael Emtinger did the WebGL framework, shaders, etc. Mark in Australia was the agency client together with Google Chrome and LEGO. The clients were really cool btw. (which is freaking rare…). ;)
And if you read this far I can give you some pro-tips regarding the Builder. You can change colors with the 0-9 keys on the keyboard. There is also a “special” hidden “my-little-pony-inspired” color(easter egg) available if you do a certain key-combination(or go by the console). Rotating bricks is quickest done by using the left/right arrowkeys… And that´s about it!
Got a chance to play with a Kinect recently, I know.. about 2 years after everyone else. :)
So I found KinectJS, that makes it really simple to get started. Just run the server and through a websocket you get access to the nodes, etc.
There are others of course, like as3NUI if you want to go with as3. Or obviously c# and c++ examples that comes with the sdk.
Since this is really hard to show online, I have tried to screenrecord some of the tests.
The first thing was just to try and get the nodes showing.
So this is just a canvas plotting the nodes as a skeleton:
Next thing I tried was some headtracking and moving a camera around accordingly to get some sort “holographic” effect.
It´s filmed with a crappy mobile-camera, sorry for that. But you should get the idea:
Then the most obvious geek-thing, control a light saber with your arm:
Test to emit particles from your hands, feels good:
Draw some trails:
Always wondered what it feels like to be a flower :D
Then a test with connecting some box2d stuff to the nodes:
Jumped around a bit to much while tesing that, broke my fucking lamp…
Then an attempt at making something more installation-like. The idea is to project this on to one wall of a room. When it detects a person it lights up like a long corridor and extends the room. And then uses headtracking to change the camera position so the perspective is correct from that persons pov. That´s the theory anyway.
Also to have some sort of interactivity and some references in the extened room, you can “throw” some balls by moving your hands in Z above a certain velocity, the balls then “inherits” the velocity of the hand.
And a variation with an object you can spin around by moving your hands.
So I have mostly tested the Kinect as an input device(which is what is.. duh), but I mean I haven´t touched the video and depthmap stuff.
And as an input device it certainly got some pros and cons. Like doing precission stuff and for example controlling something with lots of accuracy is really hard. I guess also partly cause there is no tactile feedback(a bit of the same problem as touchscreens have imo). As a result control interfaces have to be quite forgiving(for example like this)…
But on the other hand there are stuff that can feel really nice and responsive, like for example emitting particles or drawing and stuff like that. I guess you could say, creating or influencing something with motion in a void feels nicer than trying to control something with motion in a void. :)
In our business it certainly got potential for installations and similar stuff, have obviously just peaked at the surface here. Was lots of fun though!
You simply open the page, and then drag and drop a *.md2 file and it will be converted and a preview of the mesh should appear. You can then drag and drop jpg/png images for the texture to be previewed as well.
Left click and drag to rotate, right click and drag to move. Scrollwheel to zoom.
If it looks ok, enter a filename and hit “Save”.
It should now be downloaded(in Chrome at least, Firefox opens it in a new window).
You can then load in the json files into your three.js projects and use them as morphTargets.
I have only tested this in Chrome and Firefox, so not sure if it works anywhere else. Mostly done as an exercise for myself to understand the format, drag and drop and filehandling etc. But might be useful to someone else out there.
Edit (Mar 08, 2012): Looks like I had the exporter output a horizontally flipped model, should be fixed now. Thanks to @alteredq for letting me know.
Edit (May 11 2013): Updated it to export to the latest format(3.1).
Edit (Feb 10 2014): Fixed it, was broken due to some webgl changes in recent browsers.
For a recent project there was a need for lots of particles, in flashplayer 10. Here´s some of the experimentation that came out of that. There are no preloaders, so just wait for something to show(some are quite heavy).
2x pixels, heightmap/colormap
2x pixels, heightmap/colormap shapes
1x pixels, heightmap 200x200px
1x pixels, heightmap 300x300px
1x pixels, heightmap 400x400px
1x pixels, 3d teapot 50k
1x pixels, 3d teapot 100k
1x pixels, 3d teapot 200k
1x pixels, morph A (click anywhere to morph)
1x pixels, morph B (click anywhere to morph)
1x pixels, morph C (click anywhere to morph)
Lesson learned is that linked lists are way faster than arrays.. ;)
So, another year passes by. Finally managed to get the site moved to a wordpress solution this year, yay! Have had the great privilege to work on a couple of realtime 3d projects this year. First up was ROME(nominated for pca on fwa) in the beginning of the year, big, fun and challenging project built using webgl. Towards the end of the year we did Netguys, a small, short stage3D project.
I really think these technologies are great tools and will prove to be really helpful when it comes to building immersive experiences, games, etc. on teh internetz. Got a lot of potential if used right. I guess the biggest obstacle will be gpu-blacklists and crappy gpu:s, especially in the macbook-infected industry where I work. But we´ll see.
Hope you all have a nice holiday and a great 2012!
Well, I have finally joined the 21st century and moved the, almost 10 year old, html-site to a wordpress solution. Just what the world needs, another asshole with a blog…
Big thanks to Jocke and Spocke at Moxiecode for the help with the hosting! And hey, I’m using their wysiwyg-editor while writing this. Check out TinyMCE, it´s a great open-source project.
Let me know if you find something that´s not working.
Another busy year have (almost) passed, and more projects behind me. We have one site nominated at The Fwa:s Peoples Choice Awards 2010 this time, it’s July.
Things slowed down a bit towards the end of the year though. Great for me, had time to play with some mobile/android stuff. And later also try a bit of js+canvas and some WebGL. I can really see the potential. Really fun to play with from a developers point-of-view.
I also actually ended up using twitter, it’s a good work-tool/channel to see trends and what people are up to etc. You can ‘follow’ me @oosmoxiecode.
This site is nearing 10 years without a remake/update… lol. I would really like to convert it to a wordpress-solution.. some day.
Have a great 2011 everyone!
Have promised myself, as a early new years resolution, to try and be more open to shit like this. So now I´m gonna try twitter. So if you are not a stranger to bad humor, irony and foul language, you can follow me @oosmoxiecode.
Have sometimes thought I should do some sort of portfolio. It usually starts with me making a list of the sites and stuff I´ve been in involved in over the last ten years. And that´s also were it ends with me going: “Ähh fuck it… Like I have time for this…” ;)
Have uploaded some inital tests using Flash 10(in the Experiments section). Have also done some tests with Papervision3D. More to come, hopefully.
Almost a full year and no updates, that is bad. I have been home with my son for the last six months, haven´t even opened flash in that time. But that will change soon as it´s time to go back to work in January.
Flash 10 also means it’s time for me to upgrade(have basicly skipped Flash 9 so far). Hopefully there will more updates next year… ;)
I have become the father of a son. :) Check out a small clip here, of him lying around doing whatever they do.
We are recruiting! Producer and Tech Director needed for our HQ in Skellefteå! northkingdom.com/careers/
