Struct fast_surface_nets::SurfaceNetsBuffer

pub struct SurfaceNetsBuffer {
    pub positions: Vec<[f32; 3]>,
    pub normals: Vec<[f32; 3]>,
    pub indices: Vec<u32>,
    pub surface_points: Vec<[u32; 3]>,
    pub surface_strides: Vec<u32>,
    pub stride_to_index: Vec<u32>,
}

The output buffers used by surface_nets. These buffers can be reused to avoid reallocating memory.

Fields

positions: Vec<[f32; 3]>

The triangle mesh positions.

These are in array-local coordinates, i.e. at array position (x, y, z), the vertex position would be (x, y, z) + centroid if the isosurface intersects that voxel.

normals: Vec<[f32; 3]>

The triangle mesh normals.

The normals are not normalized, since that is done most efficiently on the GPU.

indices: Vec<u32>

The triangle mesh indices.

surface_points: Vec<[u32; 3]>

Local 3D array coordinates of every voxel that intersects the isosurface.

surface_strides: Vec<u32>

Stride of every voxel that intersects the isosurface. Can be used for efficient post-processing.

stride_to_index: Vec<u32>

Used to map back from voxel stride to vertex index.

Trait Implementations
