Detailed Description

A Mesh with reference counting and bounding box.

Member Function Documentation

◆ append_mesh()

void GEO::CSGMesh::append_mesh	(	const CSGMesh *	other,
		index_t	operand = `index_t(-1)`
	)

Appends a mesh to this mesh.

Parameters

[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

◆ bbox()

const Box3d & GEO::CSGMesh::bbox ( ) const

inline

Gets the bounding box.

Returns: a const reference to the bounding box, as a a Box3d. If it is a 2d mesh, then z bounds are set to 0

Definition at line 70 of file mesh_CSG.h.

◆ bbox_initialized()

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

Return values

true	if the bounding box was not changed since construction
false	otherwise

◆ may_have_intersections_with()

bool GEO::CSGMesh::may_have_intersections_with ( const CSGMesh * other ) const

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.

Parameters

[in] other a const pointer to the other mesh to be tested

Return values

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.

◆ update_bbox()

void GEO::CSGMesh::update_bbox ( )

Computes the bounding box.

This function needs to be called each time the mesh is modified
