Syntax

public static class TriangleTest

Methods

ContainedBy(XMVector, XMVector, XMVector, XMVector, XMVector, XMVector, XMVector, XMVector, XMVector)

XMVector	v1	The second vector defining the triangle.
XMVector	v2	The third vector defining the triangle.
XMVector	plane0	A vector defining the first plane.
XMVector	plane1	A vector defining the second plane.
XMVector	plane2	A vector defining the third plane.
XMVector	plane3	A vector defining the fourth plane.
XMVector	plane4	A vector defining the fifth plane.
XMVector	plane5	A vector defining the sixth plane.

Returns

Type	Description
ContainmentType	A ContainmentType value indicating whether the triangle is contained within the planes.

Intersects(XMVector, XMVector, XMVector, XMVector)

Tests whether a triangle and a plane intersect.

Declaration
