SippShaderPlanet Command

SippShaderPlanet ambient specular c3 [opacity]
This shader is a somewhat specialized shader that produces a texture that resembles a planet surface. The planet is of the Tellus type with a mixture of oceans and continents. Some of the surface is covered by semi-transparent clouds which enhances the effect greatly. On the other hand, no polar caps are provided and this decreases the realism.

The texture is 3-dimensional, so it is possible to create cube planets or even planets with cut-out parts that still have surfaces that resemble the earth surface. The texture is not scalable, and is designed to be used with texture coordinates in the range -1.0 to 1.0, e.g. a unit sphere. Of course the world coordinates need not have the same order of magnitude.

ambient is a value between 0.0 and 1.0 which determines how much of the base color of a surface that is visible when it is not illuminated by any light source.

specular is a value between 0.0 and 1.0 which is the fraction of color specularly reflected.

c3 is the shininess of the surface where 0.0 is the most dull and 1.0 is the most shiny.

opacity describes the opacity of a surface. 0.0 means totally transparent, 1.0 means totally opaque. May be a list of red, green and blue opacity values or a single value to be used for all color channels. Optional, default is 1.0.
