Expand description

A basic texture implementation. There is no UV mapping or anything like that. The method Texture::color_at should just map a point in 3D space to a color. Textures can be transformed, so color_at_shape should return the color as if the texture were not transformed. Texture::color_at_shape will perform the transformation, so it should not be overwritten. Texture::transform should return the texture transform matrix, Texture::transform_inverse should return it’s inverse. Texture::set_transform should set the texture transform to be transform.
