FunUTD

Fun Universal Texture Definitions

FunUTD is a 3-D procedural texture library running on the CPU. This is an alpha version undergoing rapid development and may contain rough edges.

Features

• Different tiling modes, including tiling of all 3 dimensions
• An endless supply of procedurally generated, self-describing volumetric textures
• Isotropic value noise, isotropic gradient noise and Voronoi bases
• Palette generation with Okhsv and Okhsl color spaces

Basics

The type returned by texture generators is Box<dyn Texture>. Texture is the trait implemented by procedural textures.

Data for procedural generation is contained in Dna objects. Generator functions draw whatever data they need from the supplied Dna object. Dna objects can be constructed full of random data from a seed value.

Textures can describe themself, that is, print the code that generates them. This is done using the get_code method. Obtained codes can be copied and pasted around and subjected to further scrutiny.

Future

Dna objects can be mutated or crossed over to create variations of genotypes or to optimize a texture for a purpose.
