Struct parry3d::transformation::voxelization::VoxelSet
source · pub struct VoxelSet {
pub origin: Point<Real>,
pub scale: Real,
/* private fields */
}
Expand description
A sparse set of voxels.
It only contains voxels that are considered as “full” after a voxelization.
Fields§
§origin: Point<Real>
The 3D origin of this voxel-set.
scale: Real
The scale factor between the voxel integer coordinates and their actual float world-space coordinates.
Implementations§
source§impl VoxelSet
impl VoxelSet
sourcepub fn voxel_volume(&self) -> Real
pub fn voxel_volume(&self) -> Real
The volume of a single voxel of this voxel set.
sourcepub fn voxelize(
points: &[Point<Real>],
indices: &[[u32; 3]],
resolution: u32,
fill_mode: FillMode,
keep_voxel_to_primitives_map: bool
) -> Self
pub fn voxelize( points: &[Point<Real>], indices: &[[u32; 3]], resolution: u32, fill_mode: FillMode, keep_voxel_to_primitives_map: bool ) -> Self
Voxelizes the given shape described by its boundary: a triangle mesh (in 3D) or polyline (in 2D).
§Parameters
points
- The vertex buffer of the boundary of the shape to voxelize.indices
- The index buffer of the boundary of the shape to voxelize.resolution
- Controls the number of subdivision done along each axis. This number is the number of subdivisions along the axis where the input shape has the largest extent. The other dimensions will have a different automatically-determined resolution (in order to keep the voxels cubic).fill_mode
- Controls what is being voxelized.keep_voxel_to_primitives_map
- If set totrue
a map between the voxels and the primitives (3D triangles or 2D segments) it intersects will be computed.
sourcepub fn min_bb_voxels(&self) -> Point<u32>
pub fn min_bb_voxels(&self) -> Point<u32>
The minimal coordinates of the integer bounding-box of the voxels in this set.
sourcepub fn max_bb_voxels(&self) -> Point<u32>
pub fn max_bb_voxels(&self) -> Point<u32>
The maximal coordinates of the integer bounding-box of the voxels in this set.
sourcepub fn compute_volume(&self) -> Real
pub fn compute_volume(&self) -> Real
Computes the total volume of the voxels contained by this set.
sourcepub fn compute_bb(&mut self)
pub fn compute_bb(&mut self)
Update the bounding box of this voxel set.
sourcepub fn compute_exact_convex_hull(
&self,
points: &[Point<Real>],
indices: &[[u32; 3]]
) -> (Vec<Point<Real>>, Vec<[u32; 3]>)
pub fn compute_exact_convex_hull( &self, points: &[Point<Real>], indices: &[[u32; 3]] ) -> (Vec<Point<Real>>, Vec<[u32; 3]>)
Compute the convex-hull of this voxel set after cutting each voxel by the primitives (3D triangle or 2D segments) it intersects.
This will panic if this VoxelSet
was created with keep_voxel_to_primitives_map = false
.
sourcepub fn compute_primitive_intersections(
&self,
points: &[Point<Real>],
indices: &[[u32; 3]]
) -> Vec<Point<Real>>
pub fn compute_primitive_intersections( &self, points: &[Point<Real>], indices: &[[u32; 3]] ) -> Vec<Point<Real>>
Computes the intersections between all the voxels of this voxel set, and all the primitives (triangle or segments) it intersected (as per the voxel-to-primitives-map computed during voxelization).
Panics if the voxelization was performed without setting the parameter
voxel_to_primitives_map = true
.
sourcepub fn compute_convex_hull(
&self,
sampling: u32
) -> (Vec<Point<Real>>, Vec<[u32; 3]>)
pub fn compute_convex_hull( &self, sampling: u32 ) -> (Vec<Point<Real>>, Vec<[u32; 3]>)
Compute the convex-hull of the voxels in this set.
§Parameters
sampling
- The convex-hull computation will ignoresampling
voxels at regular intervals. Useful to save some computation times if an exact result isn’t need. Use0
to make sure no voxel is being ignored.
