Constructor

Parameters

inShape1	The sphere to collide against triangles
inScale1	Local space scale for the sphere (scales relative to its center of mass)
inScale2	Local space scale for the triangles
inCenterOfMassTransform1	Transform that takes the center of mass of 1 into world space
inCenterOfMassTransform2	Transform that takes the center of mass of 2 into world space
inSubShapeID1	Sub shape ID of the convex object
inCollideShapeSettings	Settings for the collide shape query
ioCollector	The collector that will receive the results

Member Function Documentation

Collide()

void CollideSphereVsTriangles::Collide	(	Vec3Arg	inV0,
		Vec3Arg	inV1,
		Vec3Arg	inV2,
		uint8	inActiveEdges,
		const SubShapeID &	inSubShapeID2
	)

Collide sphere with a single triangle

Parameters

inV0,inV1,inV2	CCW triangle vertices
inActiveEdges	bit 0 = edge v0..v1 is active, bit 1 = edge v1..v2 is active, bit 2 = edge v2..v0 is active An active edge is an edge that is not connected to another triangle in such a way that it is impossible to collide with the edge
inSubShapeID2	The sub shape ID for the triangle
