Nv::Blast::BooleanTool

Defined in extensions/authoring/NvBlastExtAuthoringBooleanTool.h

Enumerations

  • Op: Operation to perform.

Functions

class BooleanTool

Tool for performing boolean operations on polygonal meshes.

Tool supports only closed meshes. Performing boolean on meshes with holes can lead to unexpected behavior, e.g. holes in result geometry.

Public Types

enum Op

Operation to perform.

Values:

enumerator Intersection
enumerator Union
enumerator Difference

Public Functions

inline virtual ~BooleanTool()
virtual void release() = 0

Release BooleanTool memory.

virtual Mesh *performBoolean(const Mesh *meshA, SpatialAccelerator *accelA, const Mesh *meshB, SpatialAccelerator *accelB, Op op) = 0

Perform boolean operation on two polygonal meshes (A and B).

Parameters

  • meshA – [in] Mesh A

  • accelA – [in] Spatial accelerator for meshA. Can be nullptr.

  • meshB – [in] Mesh B

  • accelB – [in] Spatial accelerator for meshB. Can be nullptr.

  • op – [in] Boolean operation type (see BooleanTool::Op)

Returns

new mesh result of the boolean operation. If nullptr, result is the empty set.

virtual bool pointInMesh(const Mesh *mesh, SpatialAccelerator *accel, const NvcVec3 &point) = 0

Test whether point contained in mesh.

Parameters

  • mesh – [in] Mesh geometry

  • accel – [in] Spatial accelerator for mesh. Can be nullptr.

  • point – [in] Point which should be tested

Returns

true iff point is inside of mesh
