The fast development of the Graphics Processing Unit's programmability and parallel computing power provides new solutions for visualization technology.Using ray-casting,a CUDA based interactive volume rendering tool is realized.Several rendering effects have been implemented,including alpha blending,iso-surface rendering,maximum intensity projection and X-ray projection.In order to improve alpha blending and iso-surface rendering effect,a per-pixel based Phong Lighting Model is added in.The experimental results show that the tool can make use of GPU's parallel computing capability and render high quality image.It's interactive and extensible.
