Detailed Description

Render for ray-tracing. It casts primary rays, one or more per pixel. Point of impact is then illuminated by shader.

Member Enumeration Documentation

enum FBWriteMode

Enumerator: PER_PIXEL  send colorized pixels to the frame buffer pixel by pixel PER_LINE  send colorized pixels to the frame buffer per line Definition at line 33 of file RTRender.h.

enum PixelRend

Enumerator: CENTROID  single ray casted through center of pixel area CORNERS  four rays casted through corners and interpolated CENTROID_AND_CORNERS  four rays in corners and one ray in the center of pixel area RANDOM  random rays casted through pixel area and then interp. STRATIFIED_SAMPLING  random rays through sub-pixels Definition at line 25 of file RTRender.h.
