Triangle::ProjectToAxis

Syntax

void Triangle::ProjectToAxis(const float4 &axis, float &dMin, float &dMax) const; [10 lines of code]

Projects this Triangle onto the given axis.

This function is used in SAT tests (separate axis theorem) to check the interval this triangle lies in on an 1D line.

Parameters

const float4 &axisThe axis to project onto. This vector can be unnormalized. float &dMin [out]Returns the minimum extent of this triangle on the given axis.float &dMax [out]Returns the maximum extent of this triangle on the given axis.
