Specular reflection
April 24th, 2006
Per-pixel specular lighting lets us render objects that are shiny, but not reflective like a mirror.

Still more water!
April 24th, 2006
I have updated the water again, with a focus on underwater effects!
Depth of Field
March 17th, 2006
I added depth of field effects that can be used for cutscenes. The camera can focus on any particular distance plane, and everything is blurred based on distance from this focal…
Heat haze
March 17th, 2006
I adapted the distortion system to allow for heat haze from convection in really hot environments, such as this desert:
Water refraction and volume fog
March 17th, 2006
The water now dynamically refracts objects submerged in it, and is full of floating dust so that light cannot penetrate it very far.
Screen-space distortion
March 12th, 2006
We can now apply distortion effects to anything; in this screenshot I applied a basic refraction shader to the player model! Screen-space distortion is much faster than cube map…
Water surface effects
March 6th, 2006
Today I added initial water surface reflection and refraction effects. I haven't started on underwater effects yet, but that is next!
HDR and Motion Blur
March 3rd, 2006
I just added fast approximations of motion blur and high-dynamic-range lighting. Motion blur blurs the camera image appropriately in response to really fast movements; this is not…
Model skinning
February 19th, 2006
Models can now be attached to flexible physics objects, so that they can bend and twist correctly. This means that I can apply the rabbit model to the physics-based animation…
