Plane::Intersects
Syntax
bool Plane::Intersects(const Plane &plane, const Plane &plane2, Line *outLine=0, float4 *outPoint=0) const; [45 lines of code]Computes the intersection of three planes.
This function computes the intersection of this plane, and the given two planes.
Parameters
Line *outLine [out]If the three planes are configured in such a manner that intersection is a line, this parameter receives the line of intersection. This pointer may be null.float4 *outPoint [out]If the three planes are configured in such a manner that the interesction is a point, this parameter receives the point of intersection. This pointer may be null.
Return Value
True if the intersection was a point, in which case outPoint is written to.

Tests whether this plane and the given object intersect.
The Plane-AABB intersection is implemented according to Christer Ericson's Real-Time Collision Detection, p.164.
Parameters
Line *outLine [out]The intersection of two planes forms a line. If an intersection occurs, this parameter will receive the line of intersection. This pointer may be null.float *d [out]If specified, this parameter will receive the parametric distance of the intersection point along the line object. Use the GetPoint(d) function of the line class to get the actual point of intersection. This pointer may be null.
Return Value
True if the given object intersects with this plane.
Work in progress:
Todo: in bool Plane::Intersects(const AABB &aabb) const:
Use the above form when Plane is SSE'ized.
Todo: in bool Plane::Intersects(const Triangle &triangle) const:
Add a version of Plane-Triangle intersection which returns the line segment of intersection.
Syntax
int Plane::Intersects(const Circle &circle, float4 *pt1, float4 *pt2) const; [21 lines of code]int Plane::Intersects(const Circle &circle) const; [4 lines of code]
Tests if this plane intersects with the given circle.
Parameters
float4 *pt1 [out]If specified, receives the first point of intersection. This pointer may be null.float4 *pt2 [out]If specified, receives the second point of intersection. This pointer may be null.
Return Value
The number of intersections that occurred: 0, 1 or 2.
