Shader Model 5.0

With Shader Model 5, Microsoft applies certain concepts of object-oriented programming to its shader language, HLSL. Unlike preceding versions, which introduced new capabilities (Dynamic Branching, integer support, etc.)

Increase in maximum texture size from 4K x 4K to 16K x 16K and the possibility of limiting the number of mipmaps loaded in VRAM. There’s also the possibility of changing the depth value of a pixel without disabling functionality like early Z checking, support for double-precision floating-point types, scatter memory writes, etc.

tex2D vs. tex2Dproj

texCoord(  texX, texY, texZ , texW ) means texture coordinate after transforming from the texture matrix [ position goes through world, view, projection, and texture ] . We can use texCoord to fetch texture: 1.  float4 color = tex2D( sampler,  float2( texX / texW, texY/texW ); 2.  float4 color = tex2Dporj( sampler, float4( texX, texY, texZ, texW ) ); The top-two methods will have the same result. Because tex2Dproj operator supports divide w in its interface. http://www.gamedev.net/community/forums/topic.asp?topic_id=408894 http://bbs.gameres.com/showthread.asp?threadid=104316

Fast subsurface scattering

Fig.1 - Fast Subsurface scattering of Stanford Bunny Based on the implementation of three.js . It provides a cheap, fast, and convincing approach to do ray-tracing in translucent surfaces. It refers the sharing in GDC 2011  [1], and the approach is used by Frostbite 2 and Unity engines [1][2][3]. Traditionally, when a ray intersects with surfaces, it needs to calculate the bouncing result after intersections. Materials can be divided into three types roughly.  Opaque , lights can't go through its geometry and the ray will be bounced back.  Transparency , the ray passes and allow it through the surface totally, it probably would loose a little energy after leaving.  Translucency , the ray after entering the surface will be bounced internally like below Fig. 2. Fig.2 - BSSRDF [1] In the case of translucency, we have several subsurface scattering approaches to solve our problem. When a light is traveling inside the shape, that needs to consider the diffuse value influe
