The document: http://msdn.microsoft.com/en-us/library/dd607349(v=vs.85).aspx states that #include \"foobar.fx\" will look for that file in the same directory as the current effect file.
I don\'t wish to bombard this post with code. I\'ve got a main file, fragment shader and a vertex shader file.
I am a beginner to game development and as I am used to programming in C# I decided to go for XNA. I\'ve been playing around with it for a while and now I am learning the basics of HLSL shaders, I hav
I\'m trying to write a very simple shader that adds random sparkle to applicable objects. The way I\'d like to do this is by adding a random shade of white (R = G = B) to the pixel value within the pi
Do you know how can I write simple shader (hlsl) to compare two images ? I want to get on result percent of similarity ? Is it posible to use shaders in this case ? Can I for example count red pixels
I am attempting to do some processing in the pixel shader on a texture. The data for the texture is coming from a memory chunk of 8 bit data. The problem I am facing is how to read the data in the sha
I\'m using the DirectX 9 effect framework. I\'d like to create a struct which contains a sampler like so:
