GPU Pro2 : advanced rendering techniques by WolfgangEngel

By WolfgangEngel

"This publication includes many chapters describing the newest advancements in special effects rendering at the GPU. Written through video game programming specialists, every one contribution covers complicated rendering ideas that run at the DirectX and OpenGL run-time with any shader language on hand. The book's sections disguise themes in arithmetic of special effects, rendering, international illumination, hand-held units, 3D engine layout, and GPGPU" -- learn more...

Lead-Free Soldering

The rush towards lead-free soldering in pcs, cellphones and different digital and electric units has taken on a better urgency as legislation were handed or are pending within the usa, the eu Union and Asia which ban lead-bearing solder. those new regulations on unsafe elements are altering the best way digital units are assembled, and in particular have an effect on strategy engineering, production and caliber coverage.

0 corresponds to no tree. 3. There are no strict rules on how to implement the shader. Anything that suits your needs is acceptable. When the tree density map is ready to go, we have to build a stream with world matrices for instancing. Because the tree-density map texel can enclose a huge range in world space, we cannot simply place one tree per texel because the ✐ ✐ ✐ ✐ ✐ ✐ ✐ ✐ 3. 0 f ; // C a l c u l a t e s l o p e . 0 − f slope range ; f l o a t 3 v n o r m a l = g Normalmap .

To simulate the subsurface scattering of the skin, we use the recently developed screen-space approach [Jimenez and Gutierrez 10,Jimenez et al. 10b], which transfers computations from texture space to screen space by modulating a convolution kernel according to depth information. This way, the simulation is reduced to a simple post-process, independent of the number of objects in the scene and easy to integrate in any existing pipeline. Facial-color animation is achieved using a recently proposed technique [Jimenez et al.

Our implementation follows the technique described in GPU Gems 2. We first calculate optical depth to use it as a lookup table for further generating Mie and Rayleigh textures. Mie and Rayleigh textures are updated in every frame (using rendering to multiple render targets (MRT)) and are then sampled during sky-dome rendering. This method is efficient, fast, and gives visually pleasing results. 4 we present what our rendering loop looks like. As described earlier, we perform only one full generation of procedural content whenever a collision of the camera with one of the bounding boxes is detected.
