Real Time Phong Shading
نویسنده
چکیده
Nowadays, hardware support for Gouraud shading is state-of-the-art. Most hardware implementations of the Phong shading algorithm lack flexibility, for example are restricted in the number of light sources. In this paper, we will present a concept of shading processors that has been developed in a rendering system called PROOF. Two types of processors have been designed, one performing the normalization of vectors. The other one is designed for faster and cheaper shading. The capabilities of the processors are demonstrated.

متن کاملHardware Supported Bump Mapping: A Step towards Ingber Quality Real-Time Rendering
Today's high-end Gouraud renderers produce nicely textured scenes by mapping two-dimensional images onto modeled objects in real· time. We present a renderer which textures surfaces in the normal sense of the word using bump textures to simulate wrinkled or dimpled color ful surfaces. Using a simplified bump mapping method we first suc ceeded in designing a real-time bump mapping renderer bas...

When an illumination equation has a specular reflection term, Phong shading produces more realistic results than does Gouraud shading. The specular highlights produced by Phong shading give visual information about surfac...

متن کاملEfficient Point-Based Rendering Using Image Reconstruction
Image-space reconstruction of continuous surfaces from scattered one-pixel projections of points is known to potentially offer an advantageous time complexity compared to surface splatting techniques. We propose a new algorithm for hardware-accelerated image-space reconstruction using pull-push interpolation and present an efficient GPU implementation. Compared to published image-space reconstr...
