A color source shader is used to define the color of a surface at any point in space. It may be as simple as a plain color (which specifies all parts of the surface to have a uniform color), or it may define complex surface patterns such as marble or wood.
Every surface must have a color source shader associated with it, and for a given surface its color source shader will only be called for those pixels (if any) at which the surface is known to be visible.
We provide herewith names and descriptions of color source shaders:
"absolute curvature"
False color shader to show the absolute curvature of a surface.
"base"
Base color derived from color values supplied at vertices of polygonal geometry.
"blue marble"
A blue marble pattern.
"chrome"
Chrome-like reflections.
"cubes"
A three-dimensional lattice of cubes with alternating colors.
"decal"
Color shader to support decals.
"decal uv"
A color shader specific for labelling.
"gaussian curvature"
False color shader to show the gaussian curvature of a surface.
"geometric curvature"
General purpose false color shader which can show either absolute, gaussian, or mean curvature.
"marble"
A marble pattern.
"mean curvature"
False color shader to show the mean curvature of a surface.
"plain"
A plain, uniform color.
"solid clouds"
A cloudy appearance.
"solid polka"
A solid polka dot pattern.
"surface evaluation"
Color shader which simulates reflection of a cylinder with longitudinal bands surrounding the surface being considered. Gives good visual clues to the surfaces curvature.
"wood"
A simple wood pattern with concentric rings of light and dark wood.
"wrapped brick"
A wrapped brick pattern.
"wrapped checker"
A wrapped checker board pattern.
"wrapped diagonal"
A pattern giving a line across the leading diagonal of the texture space.
"wrapped filtered image"
A wrapped texture to provide image color mapping with additional color filtering.
"wrapped grid"
A grid color pattern.
"wrapped image"
A wrapped texture to provide image color mapping.
"wrapped polka"
A wrapped polka dot pattern.
"wrapped s stripe"
A pattern giving a line along the s-axis of the texture space.
"wrapped t stripe"
A pattern giving a line along the t-axis of the texture space.
"wrapped textured brick"
A wrapped textured brick pattern.
