Improved ray casting algorithm based on GPU programming

Year: 2012

Type: article

Abstract: For the low sampling efficiency and poor sampling efficiency in the traditional ray casting algorithm,a volume rendering algorithm with a new sample synthesis function is proposed.This algorithm applies Blinn-Phong illumination model and uses early opacity termination.It's implemented by vertex programs and fragment programs in Cg language.The results of experiment show that this algorithm can not only enhance the effect of traditional ray-casting algorithm,but also accelerate the speed of the algorithm.
