Detailed Description

Style to control the look of slabs. The slab renderer uses texture arrays for rendering. A texture index can be specified for each slab, which is used to access the texture array. Ech slab texture must therefore have the same resolution. For animated slabs store the timesteps for each slab in a non-interleaved fashion in the texture array. Set the tex_idx_stride to the number of animation frames. The tex_idx_offset can be used to select the rendered time step.
