Member Function Documentation

void Nv::Blast::TriangleProcessor::buildConvexHull	(	std::vector< PxVec3 > &	points,
		std::vector< PxVec3 > &	convexHull,
		const PxVec3 &	normal
	)

Builds convex polygon for given set of points. Points should be coplanar.

Parameters:

[in]	points	Input array of points
[out]	convexHull	Output polygon
[in]	normal	Normal vector to polygon.

uint32_t Nv::Blast::TriangleProcessor::getSegmentIntersection	(	const PxVec2 &	s1,
		const PxVec2 &	e1,
		const PxVec2 &	s2,
		const PxVec2 &	e2,
		PxF32 &	t1
	)

Segment intersection point

Parameters:

[in]	s1	Segment-1 start point
[in]	e1	Segment-1 end point
[in]	s2	Segment-2 start point
[in]	e2	Segment-2 end point
[out]	t1	Intersection point parameter relatively to Segment-1, lies in [0.0, 1.0] range.

Returns:

0 if there is no intersections, 1 - if intersection is found.

uint32_t Nv::Blast::TriangleProcessor::getTriangleIntersection	(	TrPrcTriangle &	a,
		TrPrcTriangle2d &	aProjected,
		TrPrcTriangle &	b,
		PxVec3 &	centroid,
		std::vector< PxVec3 > &	intersectionBuffer,
		PxVec3	normal
	)

Build intersection between two triangles

Parameters:

[in]	a	First triangle (A)
[in]	aProjected	Projected triangle A
[in]	b	Second triangle (B)
[in]	centroid	Centroid of first triangle (A)
[out]	intersectionBuffer	Result intersection polygon
[in]	normal	Normal vector to triangle (Common for both A and B).

Returns:

1 - if if intersection is found.

uint32_t Nv::Blast::TriangleProcessor::isPointInside	(	const PxVec2 &	point,
		const TrPrcTriangle2d &	triangle
	)

Test whether point is inside of triangle.

Parameters:

[in]	point	Point coordinates in 2d space.
[in]	triangle	Triangle in 2d space.

Returns:

1 - if inside, 2 if on edge, 0 if neither inside nor edge.

void Nv::Blast::TriangleProcessor::sortToCCW	(	std::vector< PxVec3 > &	points,
		PxVec3 &	normal
	)

Sort vertices of polygon in CCW-order

bool Nv::Blast::TriangleProcessor::triangleBoundingBoxIntersection	(	TrPrcTriangle2d &	a,
		TrPrcTriangle2d &	b
	)

Test whether BB of triangles intersect.

Parameters:

[in]	a	First triangle (A)
[in]	b	Second triangle (B)

Returns:

true - if intersect
