enum | MeshElementsFlags |
Indicates the mesh elements (vertices, facets or cells) present in a mesh. More... | |
A Mesh with reference counting and bounding box.
Definition at line 61 of file mesh_CSG.h.
Appends a mesh to this mesh.
[in] | other | a const pointer to the mesh to be appended |
[in] | operand | an optional operand id, or index_t(-1) if not setting operand_bit attribute |
Copies all the vertices and the facets of other
|
inline |
Gets the bounding box.
Definition at line 70 of file mesh_CSG.h.
bool GEO::CSGMesh::bbox_initialized | ( | ) | const |
Tests whether the bounding box was initialized.
Used for debugging purposes, for instance, to detect that the bounding box of a mesh was not properly updated
true | if the bounding box was not changed since construction |
false | otherwise |
|
inline |
Tests whether this mesh may have an intersection with another mesh.
Tests the bounding boxes for intersection. To be used as a filter before calling the (costly) intersection algorithm.
[in] | other | a const pointer to the other mesh to be tested |
false | if there is no intersection with other |
true | if there is possibly an intersection, but there may be false positives |
Definition at line 110 of file mesh_CSG.h.
void GEO::CSGMesh::update_bbox | ( | ) |
Computes the bounding box.
This function needs to be called each time the mesh is modified
