◆ add_array()
| void BulletTriangleMesh::add_array | ( | const PTA_LVecBase3 & | points, |
| const PTA_int & | indices, | ||
| bool | remove_duplicate_vertices = false |
||
| ) |
Adds triangle information from an array of points and indices referring to these points.
This is more efficient than adding triangles one at a time.
If remove_duplicate_vertices is true, it will make sure that it does not add duplicate vertices if they already exist in the triangle mesh, within the tolerance specified by set_welding_distance(). This comes at a significant performance cost, especially for large meshes.
Definition at line 319 of file bulletTriangleMesh.cxx.
◆ add_geom()
| void BulletTriangleMesh::add_geom | ( | const Geom * | geom, |
| bool | remove_duplicate_vertices = false, |
||
| const TransformState * | ts = TransformState::make_identity() |
||
| ) |
Adds the geometry from the indicated Geom from the triangle mesh.
This is a one-time copy operation, and future updates to the Geom will not be reflected.
If remove_duplicate_vertices is true, it will make sure that it does not add duplicate vertices if they already exist in the triangle mesh, within the tolerance specified by set_welding_distance(). This comes at a significant performance cost, especially for large meshes.
Definition at line 205 of file bulletTriangleMesh.cxx.
◆ add_triangle()
| void BulletTriangleMesh::add_triangle | ( | const LPoint3 & | p0, |
| const LPoint3 & | p1, | ||
| const LPoint3 & | p2, | ||
| bool | remove_duplicate_vertices = false |
||
| ) |
Adds a triangle with the indicated coordinates.
If remove_duplicate_vertices is true, it will make sure that it does not add duplicate vertices if they already exist in the triangle mesh, within the tolerance specified by set_welding_distance(). This comes at a significant performance cost, especially for large meshes.

| const LPoint3 & | p1, | ||
| const LPoint3 & | p2, | ||
| bool | remove_duplicate_vertices = false |
||
| ) |
Adds a triangle with the indicated coordinates.
If remove_duplicate_vertices is true, it will make sure that it does not add duplicate vertices if they already exist in the triangle mesh, within the tolerance specified by set_welding_distance(). This comes at a significant performance cost, especially for large meshes. Assumes the lock(bullet global lock) is held by the caller

◆ do_get_num_triangles()

Returns the number of triangles in this triangle mesh.

◆ preallocate()
| void BulletTriangleMesh::preallocate | ( | int | num_verts, |
| int | num_indices | ||
| ) |
Used to reserve memory in anticipation of the given amount of vertices and indices being added to the triangle mesh.
This is useful if you are about to call add_triangle() many times, to prevent unnecessary reallocations.

◆ set_welding_distance
| void BulletTriangleMesh::set_welding_distance |
Sets the square of the distance at which vertices will be merged together when adding geometry with remove_duplicate_vertices set to true.
The default is 0, meaning vertices will only be merged if they have the exact same position.
