Abstract:
We present a system for the real-time rendering of scenes to produce images like watercolour paintings. Our system uses a hybrid of object space rendering techniques and image plane post processing to attain extremely good results very quickly. We achieve this through graphics processing unit (GPU) programming, hardware accelerated shadow volumes, and the use of noise for various different tasks. We manage to circumvent problems found in both previous image space and object space methods by combining the two.
