sharing is fun 2fer - Reflection / Refraction


    Sep 14 2007 | 3:33 am
    Here's today's bonus patch showing how to do reflection and refraction with shaders. The shader implements a basic Fresnel model which is controllable via bias, scale and falloff parameters. These control the ratio of the reflection and refraction colors based on surface orientation to the camera. The texture lookup is done using a sphere-map so the quality is not as good as it would be with a cube map. Still, it's quite nice.
    enjoy. wes
