Private Methods
void __fastcall	PaintGL ()
	PaintGL is redrawing the precalculated view in the OpenGL-Window - if the window size changes, PrepareGLWindow has to be called first to calculate the new aspect ratio.
void __fastcall	PrepareGLWindow ()
	Aspect ratio and Position of the GLWindow within the client area of the window are recalculated in PrepareGLWindow, this is necessary whenever the window was resized.
void __fastcall	RayCast ()
	RayCast has to be called after one or more of the raycaster parameters have been changed.

Detailed Description

MDI-Child for the NPR-Raycaster.

The Non-Photorealistic Raycaster tries to emphasize object contours by viewing gradient values rather than data values. The gradient values are multiplied by view-dependent intensities that result from the viewing vector multiplied by the gradient vector.

Aspect ratio and Position of the GLWindow within the client area of the window are recalculated in PrepareGLWindow, this is necessary whenever the window was resized. An additional call to PaintGL is neccessary to redraw the changes. Definition at line 150 of file MDINPR.cpp. Referenced by PaintGL().

void __fastcall TNPRForm::RayCast (    )  [private]

RayCast has to be called after one or more of the raycaster parameters have been changed. The raycaster will reset all values and recalculate the whole viewing array again. An additional call to PaintGL is neccessary to redraw the changes. Definition at line 230 of file MDINPR.cpp. References rgb::b, rgb::g, rgb::r, vertex::x, vertex::y, and vertex::z.
