Procedural Equirectangular Textures

Planet

This texture generates the surface colors of a planet. There are seven types of terrains groups into three clusters: water (deep and shallow), land (beach, low land and high land) and mountains (rocky and snowy parts). The generated texture is for color maps. Click on a snapshot to open it online.

• texture( {params} ) – generator for a texture with given parameters
• defaults – object with default parameters
