PlaneOptimalShadowCameraSetup (MovablePlane *plane) | |
Constructor -- requires a plane of interest. | |
virtual | ~PlaneOptimalShadowCameraSetup () |
Destructor. | |
virtual void | getShadowCamera (const SceneManager *sm, const Camera *cam, const Viewport *vp, const Light *light, Camera *texCam) const |
Returns shadow camera configured to get 1-1 homography between screen and shadow map when restricted to plane. | |
Private Member Functions | |
PlaneOptimalShadowCameraSetup () | |
Default constructor is private. | |
Matrix4 | computeConstrainedProjection (const Vector4 &pinhole, const std::vector< Vector4 > &fpoint, const std::vector< Vector2 > &constraint) const |
helper function computing projection matrix given constraints | |
Private Attributes | |
MovablePlane * | m_plane |
pointer to plane of interest |
Second important note: this projection also only works for lights with a finite position. Therefore you cannot use it for directional lights at this time.
