Hi all. My doubt is how achieve shift operation in Shader. // CPU code. byte lsbValue; byte msbValue; short t = ( msbValue<<8) + lsbValue; // How to achieve this in shader. float fmsb; float flsb; float fShortValue = ( ( fmsb * MAXVALUE) *MAXVALUE + flsb*MAXVALUE ) / ( MAXVALUE*MAXVALUE ) where maxVALUE IS maximum value of a component ( say 256 ) is it correct.

I have these lines in an fx file #define MAX_LIGHTS 4 float4 lightDirections[MAX_LIGHTS] : LightDirections; float4 lightColors[MAX_LIGHTS] : LightColors; bool lightEnables[MAX_LIGHTS] : LightEnables; Can someone tell me what format the data passed to ID3XEffect::SetValue needs to be to match with each of these in my shader?

The March2008 SDK has a changed behavior: SM3 shaders using any global variables defined as type 'half' will no longer compile, unless you set the compile option flag D3DXSHADER_ENABLE_BACKWARDS_COMPATIBILITY. Only the error message when attempting to compile the shader says anything about this (grr). My question is this: Is this the only thing this flag does in...
