Collision Detection Updates: Demo Pages

Patrick Lam | 13 February, 2009 | 23:15
The collision detection has the basic tests functioning and are performing well. The hard part is starting now. What I am currently working on and aim to have these done for my next release are as follow:
  • Create a function which returns the object’s next position: getNextPosition(timeSpan)
  • Create a function which returns the bounding volume of the object
    • think of it as a stretched bounding sphere which encloses the objects current position and it’s future position
  • Break down the updates into smaller test, so it doesn’t skip any collisions in between the updates
  • Extract the collision detection test out from the scene class, and write it as a class of its own
So far I have the 1st task completed (getNextPosition). And now I am working on the 3rd and 4th task. I will most likely work on the 4th task first before I continue with any other coding for collision detection.

On a side note, I have posted up more demos of the collision detection. Right now there is a 3rd one, which includes the triangle-triangle testing, and also a brief explaination between the difference of having it and not.

The links are all posted here: http://matrix.senecac.on.ca/~pplam3/
And if you want to just go straight to the demos, here are the links to them.

A spec change that keeps coming back to haunt me

At some point, the way firefox handles keyboard events changed. I’m not sure exactly when it happened, all I know is that it broke how I was dealing with keyboard interaction on almost every demo I’ve written (for example,the mocap demo and MotionView). When I wrote the demos, the keydown event would be fired once, [...]

Release 2.2

The 2.2 Release of the Canvas 3D Library includes a number of new features, updates to old features and fixes for several bugs along with the requisite changes to meet the evolving WebGL spec. Some of the things included (in no particular order) are: Better picking code. The ability to swap textures as a scene [...]
