ANTI-ALISING
Ray tracing allows for perfect sub-pixel anti-aliasing, by randomizing the ray origin for each pixel and averaging the results.
DEPTH OF FIELD
A camera lens can be simulated, offering photorealistic depth-of-field and focal point.
GLASS SIMULATION
Schlick’s approximation is used to determine the ratio between reflection and transmittance when colliding with translucent objects. Resulting in realistic zoomed and flipped images
