RT

Ray marching based ray tracer. Currently only OSX supported.

How to build

for multithreaded build make -j <num threads>.
typically, make -j 4.

Usage

./RT <scene>
example scenes are given in ./scenes directory

Keys

Camera movements and rotations

w a s d q e j k h l to move and rotate camera?
space to reset camera position

Post processing toggling

1 for antialiasing
2 for carton-filter
3 for sepia

Screenshot key

P to take screenshot

Screenshots

Physically based rendering and global illumination...

Many objects...

Mandelbulb...

normal/texture mapping...

And constructive solid geometry!

Including smoothed versions!
