Member Function Documentation

ComputeNbBoundaryEdges()

PxU32 AdjTriangle::ComputeNbBoundaryEdges

(

)

const

Computes the number of boundary edges in a triangle.

Returns

the number of boundary edges. (0 => 3)

ComputeNbNeighbors()

PxU32 AdjTriangle::ComputeNbNeighbors

(

)

const

Computes the number of valid neighbors.

Returns

the number of neighbors. (0 => 3)

Flip()

PX_IMPLEMENT_OUTPUT_ERROR void AdjTriangle::Flip

(

)

Flips the winding.

HasNeighbor()

bool AdjTriangle::HasNeighbor	(	PxU32	tref,
		PxU32 *	index = NULL
	)		const

Checks whether the triangle has a particular neighbor or not.

Parameters

tref	[in] the triangle reference to look for
index	[out] the corresponding index in the triangle (NULL if not needed)

Returns

true if the triangle has the given neighbor

Member Data Documentation

mATri

PxU32 physx::Gu::AdjTriangle::mATri[3]

Links/References of adjacent triangles. The 2 most significant bits contains the counterpart edge in the adjacent triangle. mATri[0] refers to edge 0-1 mATri[1] refers to edge 0-2 mATri[2] refers to edge 1-2
