Texturemaps

Let's add some character to the cueball. We'll add a texturemap marble effect to simulate chalk marks on the ball.

The script would look like:

<libpath "c:\w3\"> <lib "textures.w3d"> <seed 10> This sets the randon number generator to a certain point in the random sequence, as long as this is the same, the texturemapper will produce the same result.     <normalize> Pool ball:     <position 0 0 0> <radius 3>     <apply "glossy">     <reflectivity 0.1>     <color 1 0 0>     <imagemap "c:\imagemaps\raytrace_imagemap_1.jpg">      <object sphere "My Sphere">     <normalize> Cue Ball:     <position -7 0 0> <radius 3>     <apply "glossy">     <reflectivity 0.1>     <specular 0>     <roughness 0>     With these two, we make the cueball look less shiny and more chalked and worn.     <color 1 1 1>     <color 0 0.5 1>     Set the colors for the texturemap, color0 is the color of the ball, color1 is the color of the chalk.     <texturemap "marble" 0.01 30>     This adds a marble effect to the cueball, giving it a chalked look. See the language reference on texturemapping for more info.      <object sphere "My Sphere">     <normalize> <object bound> Light:     <position 50 50 -75>     <color 1 1 1> <object light "light_1"> <viewlocation 0 0 14> <viewtarget -3 0 0>

This is the end product of the script.
