Copy brick data into the atlas at the given position.

pub fn sample_atlas(&self, world_pos: Vec3, lod: f32) -> Vec4

Sample the atlas at a world position using trilinear interpolation with LOD.

pub fn stats(&self) -> AtlasStats

pub fn defragment(&mut self)

Defragment the atlas by repacking all bricks contiguously.

pub fn remove_brick(&mut self, index: usize)

Remove a brick by index.
