Trait transvoxel::voxel_source::VoxelSource

pub trait VoxelSource<D: Density> {
    fn get_density(&mut self, voxel_index: &RegularVoxelIndex) -> D;
    fn get_transition_density(&mut self, index: &HighResolutionVoxelIndex) -> D;
}

Wrapper used to retrieve density values for a Block (typically from an underlying ScalarField) This source is accessed through voxel_coordinates structs

Required methods

fn get_density(&mut self, voxel_index: &RegularVoxelIndex) -> D

This method will be called by the extraction algorithm, for regular voxels

It should return the density, at the “base” (lowest corner) of the cell identified by the given voxel index

Note that, when computing gradients, this may be queried for cells outside of the extracted block:

• an index of 0 indicates the base of the block
• an index of subdivisions indicates the end of the block
• the function can be called for index values between -1 and subdivisions + 1 (both included)

fn get_transition_density(&mut self, index: &HighResolutionVoxelIndex) -> D

If the extraction needs to handle some transition faces, this method will be called to get density for non regular voxels It will only get called for non-regular voxels (ie odd u/v and/or non-zero w): For example for U=2,V=0,W=0 the algorithm will try to call get_density instead
