URL String variables have been defined in the Laser global environment
for all of these files. You can evaluate the code on this page with the Laser expression
(include FILE.lsr) where FILE is the name of the file as listed below.

A sample of Ripple bump mapping.
This program evaluates to a scene of a sphere of water
in the center of a rippled plane.
The plane is really flat; the rippling surface is created by changing the normal
based on distance from the center of the plane. Laser supports
simultaneous mapping of any surface feature, such as texture
mapping, transparency, emissivity, surface normal, surface
intersection, etc.

Evaluates to a scene of a reflective, metalic sphere with four
golden tentacles stretching out and back inside itself. The tentacles
are created using recursive procedures.
|
|
Evaluates to a scene filled with random reflective cubes. Creates a procedure
make-random-cube, then calls it multiple times to fill the scene.
The default color space environment map is used, with a rotated
viewer to see the yellow/red portion.

|
Evaluates to a scene of a reflective red sphere on a
black and white reflective checker board (texture mapped) plane.

|
An underwater scene demonstrating the use of bump mapping, environment diffusion, and optimization.
To simulate an under sea location, the water surface is wavy and reflective, and the environment is filled with translucent blue water.
The sandy bottom is bump mapped, and for rendering speed, cannot cast shadows.

|
Evaluates to the default scene; a gray sphere with a colorspace
environment map. Diffuse shading and specular hilight from the default
directional light (upper left hand light source) can be seen.
