pub fn bounding_sphere(
&self,
pos: &Isometry<f32, Unit<Quaternion<f32>>, 3_usize>
) -> BoundingSphere
pub fn bounding_sphere(
&self,
pos: &Isometry<f32, Unit<Quaternion<f32>>, 3_usize>
) -> BoundingSphere
Computes the world-space bounding sphere of this triangle mesh, transformed by pos
.
Computes the local-space bounding sphere of this triangle mesh.
Creates a new triangle mesh from a vertex buffer and an index buffer.
Compute the axis-aligned bounding box of this triangle mesh.
Gets the local axis-aligned bounding box of this triangle mesh.
The number of triangles forming this mesh.
Does the given feature ID identify a backface of this trimesh?
An iterator through all the triangles of this mesh.
A flat view of the index buffer of this mesh.
Remove all duplicate vertices and adjust the index buffer accordingly.
This is typically used to recover a vertex buffer from which we can deduce adjacency information. between triangles by observing how the vertices are shared by triangles based on the index buffer.
Computes the pseudo-normals used for solid point-projection.
This computes the pseudo-normals needed by the point containment test described in “Signed distance computation using the angle weighted pseudonormal”, Baerentzen, et al. DOI: 10.1109/TVCG.2005.49
For the point-containment test to properly detect the inside of the trimesh (i.e. to return
proj.is_inside = true
), the trimesh must:
- Be manifold (closed, no t-junctions, etc.)
- Be oriented with outward normals.
If the the trimesh is correctly oriented, but is manifold everywhere except at its boundaries, then the computed pseudo-normals will provide correct point-containment test results except for points closest to the boundary of the mesh.
It may be useful to call self.recover_topology()
before this method, in order to fix the
index buffer if some of the vertices of this trimesh are duplicated.
