Recursive Ray Tracing Basic ray tracing results in basic Phong illumination plus hidden surfaces.
{"Image DocumentName": "Recursive Ray TracingBasic ray tracing results in basic Phong illumination plus hidden surfaces.", "Image ImageDescription": "Shadows require only one extra ray per light source. Shadow rays do not reflect or refract. No need to find the closest object, only need to hit once before reaching the light. Reflection and refraction rays add a lot to the images. Reflection and refraction can spawn many new rays since light can keep bouncing.", "Image XResolution": "37", "Image YResolution": "37", "Image ResolutionUnit": "Pixels/Centimeter", "Image Software": "SlidePlayer", "Image YCbCrPositioning": "Centered"}
