Detailed Description

USED FOR DISPATCHING threadsd of execution.

Thread specific copies of important internal buffers.

Definition at line 200 of file RENDER.H.

Data Fields
UCHAR *	ram
	Pointer to the base memory from which all other variable are offset.
long *	Zbuffer
	Array holding identity of face visible in each pixel on the scanline.
long *	Xbuffer
	Arry identifying face on previous line rendering. This is used in the anti-aliasing algorithm so that the same value does not have to be rendered twice - to save time.
long *	Zobject
	Array holding identity of object visible in each pixel on the scanline.
long *	Xobject
	Arry identifying face on previous line rendering (see Xbuffer description).
long *	Zglass [NGLASS]
	Identity of face in glass layer in each scanline pixel. Un to NGLASS glass layers.
long *	ZglassO [NGLASS]
	Identity of object in, up to NGLASS, glass layers.
double *	Zdepth
	Depth buffer value in pixels on scanline.
double *	Zposn
	fractional pixel offset in pixels on scanline
double *	Zglassd [NGLASS]
	Depth buffer for glass faces in pixels on scanline.
double *	Zground
	Fractional ratio for pixels with ground visible. Used to accelerate calculations.
UCHAR *	Red
UCHAR *	Green
UCHAR *	Blue
UCHAR *	Alfa
UCHAR *	L_Red
UCHAR *	L_Green
UCHAR *	L_Blue
UCHAR *	L_Alfa
UCHAR *	LL_Red
