A strategy for merging cube faces into quads.

type Voxel

Required Methods

unsafe fn find_quad(
    min_index: u32,
    max_width: u32,
    max_height: u32,
    face_strides: &FaceStrides,
    voxels: &[Self::Voxel],
    visited: &[bool]
) -> (u32, u32) where
    Self::Voxel: Voxel, 

Return the width and height of the quad that should be constructed.

min_index: The linear index for the minimum voxel in this quad.

max_width: The maximum possible width for the quad to be constructed.

max_height: The maximum possible height for the quad to be constructed.

face_strides: Strides to help with indexing in the necessary directions for this cube face.

voxels: The entire array of voxel data.

visited: The bitmask of which voxels have already been meshed. A quad’s extent will be marked as visited (true) after find_quad returns.

Safety

Some implementations may use unchecked indexing of voxels for performance. If this trait is not invoked with correct arguments, access out of bounds may cause undefined behavior.
