Ok, I finally managed to get it working correctly, at least when the screen normal is perpendicular to the z axis, and the virtual screen is centered around
( screenWidth / 2, screenHeight / 2).

The effect is really impressive, so check out my quick and dirty code release:

Simply changing the view ( camera position and target ) works, but it does not reflect the true geometry.
If you look at your screen (being the "projection plane" in the virtual world) from an angle, it's plane is not perpendicular to the viewing direction. That's why the frustrum needs to be ...

Hi,

I'm trying to get head tracking to work with Irrlicht (see Johnny Lee's Wii remote head tracking on youtube).
When figuring out the projection matrix I read that OpenGl and DirectX have different conventions:

OpenGL has the viewing direction in negative z direction (right handed) and projects ...

Ah, ok, the projection is being applied now.

I'm using a webcam (with sunglasses as filter) that tracks two bright red leds that are attached to some glasses.
This works ok, at least in a dark room.
You don't really need irleds, because the cmos sensor is sensitive enough in that part of the ...

Hi,

I'm trying to get setTransform to work for headtracking. But while the generated projection matrix changes a desired, there is no change in the graphical output.


float nearPlane = 0.05;
matrix4 projectionMatrix = make_projection_matrix( nearPlane*( -0.5 * aspectRatio + headPosition.X)/ d ...
