Struct GeometryPixel 

#[repr(C)]
pub struct GeometryPixel {
    pub normal: [f32; 3],
    pub depth: u32,
}

Pixel type for a voxel::Image

This type can be passed directly in a buffer to the GPU. However, it is unwise to load it as a GPU texture: because it mixes f32 and u32, there’s not a reasonable interpolation mode. Putting the whole thing into an f32x4 texture is especially unwise: bitcasting a small u32 depth to a f32 produces a denormalized float, which some GPUs will flush to 0.0 (surprise!).

Fields

normal: [f32; 3]

Function gradients at this pixel

depth: u32

Z position of this pixel, in voxel units

The fractional component is always zero. Empty pixels always have a depth of 0.
