IntroductionPuppy Ray (aka PuppyRay) is a raytracer, or more technically precise: a ray caster. It is software that is included in PD Artist and PD Howler (with animation).
The main purpose of Puppy Ray is to render landscapes from a combination of image resources:
- the elevation map, found in the Main image. It can be an animation.
- the colormap or texture map, found in the underlying Swap image. It can be animated too (stored animation used as animated Swap)
- the surrounding Sky map, from multiple presets or a custom sky from the image(s) loaded in a Custom brush. It can be animated,
All of these can be animations: The elevation map can be an animation, the color/texture map can be a stored animation made to act as animated Swap image sequence, and the custom brush can be an animate brush.
You may have seen a number of tutorials an examples of how to use PuppyRay to create fancy renderings of endless terrains. The patch of terrain that is defined by the elevation map is tiled repeatedly until it disappears in the distant fog.
