I can't find any useful information on packing 4 values into a 32 bit float in HLSL.

Ideally, what I want to be able to do in HLSL is:

float4 values = ... // Some values where each component is between 0 and 1.
float packedValues = pack32R(values);
float4 values2 = unpack32R(packedValues);

I realize that there will be precision limitations, and performance tradeoffs between different precisions in different methods. I'm just wondering what ideas are out there.

Thanks for wanting to help! I'm trying to create a circular, repeating ring (that moves outward) on a texture. I've achieved this, to a degree, with the following code: float distance = length(inTex - in_ShipCenter); float time = in_Time; ///* Simple distance/time combination */ float2 colorIndex… >>> More

As far as I know, certain mathematical functions like FFTs and perlin noise, etc. can be much faster when done on the GPU as a pixel shader. My question is, if I wanted to exploit this to calculate results and stream to bitmaps, could I do it without needing to actually display it in Silverlight or… >>> More

I'm trying to implement a so-called ping-pong technique in XNA; you basically have two RenderTarget2D A and B and at each iteration you use one as texture and the other as target - and vice versa - for a quad rendered through an HLSL pixel shader. step1: A--PS--B step2: B--PS--A step3: A--PS--B … >>> More
