Frustum::PointInside

Syntax

float4 Frustum::PointInside(float x, float y, float z) const; [6 lines of code]
float4 Frustum::PointInside(const float4 &xyz) const; [1 lines of code]

Returns a point inside this frustum parameterized by three scalar coordinates.

Note
This function is slightly different than multiplying by inv(view*proj), since depth is handled linearly.

Parameters

floatxThe horizontal normalized viewport coordinate in the range [-1, 1]. floatyThe vertical normalized viewport coordinate in the range [-1, 1]. floatzThe linear depth coordinate in the range [0, 1].
