Detailed Description

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.

Mesh* Nv::Blast::BooleanEvaluator::createNewMesh

(

)

Generates result polygon mesh after performing boolean operation.

Returns:

If not nullptr - result mesh geometry.

int32_t Nv::Blast::BooleanEvaluator::isPointContainedInMesh	(	const Mesh *	mesh,
		SpatialAccelerator *	spAccel,
		const NvcVec3 &	point
	)

Test whether point contained in mesh.

Parameters:

[in]	mesh	Mesh geometry
[in]	spAccel	Acceleration structure for mesh
[in]	point	Point which should be tested

Returns:

not 0 if point is inside of mesh

int32_t Nv::Blast::BooleanEvaluator::isPointContainedInMesh	(	const Mesh *	mesh,
		const NvcVec3 &	point
	)

Test whether point contained in mesh.

Parameters:

[in]	mesh	Mesh geometry
[in]	point	Point which should be tested

Returns:

not 0 if point is inside of mesh

void Nv::Blast::BooleanEvaluator::performBoolean	(	const Mesh *	meshA,
		const Mesh *	meshB,
		BooleanConf	mode
	)

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

Parameters:

[in]	meshA	Mesh A
[in]	meshB	Mesh B
[in]	mode	Boolean operation type

void Nv::Blast::BooleanEvaluator::performBoolean	(	const Mesh *	meshA,
		const Mesh *	meshB,
		SpatialAccelerator *	spAccelA,
		SpatialAccelerator *	spAccelB,
		BooleanConf	mode
	)

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

Parameters:

[in]	meshA	Mesh A
[in]	meshB	Mesh B
[in]	spAccelA	Acceleration structure for mesh A
[in]	spAccelB	Acceleration structure for mesh B
[in]	mode	Boolean operation type

void Nv::Blast::BooleanEvaluator::performFastCutting	(	const Mesh *	meshA,
		const Mesh *	meshB,
		BooleanConf	mode
	)

Perform cutting of mesh with some large box, which represents cutting plane. This method skips part of intersetion computations, so should be used ONLY with cutting box, received from getBigBox(...) method from NvBlastExtAuthoringMesh.h. For cutting use only BOOLEAN_INTERSECTION or BOOLEAN_DIFFERENCE mode.

Parameters:

[in]	meshA	Mesh A
[in]	meshB	Cutting box
[in]	mode	Boolean operation type

void Nv::Blast::BooleanEvaluator::performFastCutting	(	const Mesh *	meshA,
		const Mesh *	meshB,
		SpatialAccelerator *	spAccelA,
		SpatialAccelerator *	spAccelB,
		BooleanConf	mode
	)

Perform cutting of mesh with some large box, which represents cutting plane. This method skips part of intersetion computations, so should be used ONLY with cutting box, received from getBigBox(...) method from NvBlastExtAuthoringMesh.h. For cutting use only BOOLEAN_INTERSECTION or BOOLEAN_DIFFERENCE mode.

Parameters:

[in]	meshA	Mesh A
[in]	meshB	Cutting box
[in]	spAccelA	Acceleration structure for mesh A
[in]	spAccelB	Acceleration structure for cutting box
[in]	mode	Boolean operation type

void Nv::Blast::BooleanEvaluator::reset

(

)

Reset tool state.
