now from what i understand of vertex shaders the main runs for every vertex. I am just not understanding what is happening here for some reason its like a snake i cant see that is sitting on my face. could some one explain what is happening here just a little bit perhaps?
[source lang="cpp"]cbuffer c_buffer{ float4x4 World; float4x4 WorldViewProj; float4x4 FinalTransforms[32];}struct VS_OUT{ float4 position : SV_POSITION;};VS_OUT VShader(float4 position : POSITION, float4 weights : BLENDWEIGHT, int4 boneIndices : BLENDINDICES){ VS_OUT output; float4 p = float4(0.0f, 0.0f, 0.0f, 1.0f); float lastWeight = 0.0f; int n = 3; for(int i = n; i > 0; i--) { lastWeight += weights[i]; p += weights[i] * mul(FinalTransforms[boneIndices[i]], position); } lastWeight = 1.0f - lastWeight; p += lastWeight * mul(FinalTransforms[boneIndices[0]], position); p.w = 1.0f; output.position = mul(WorldViewProj, p); return output;}[/source]


I should also add that i am using opengl and am used to using GLSL when it comes to shader so i am also a little puzzled by the way your reading in uniform variables. I assume that this "float4 position : POSITION, float4 weights : BLENDWEIGHT, int4 boneIndices : BLENDINDICES" is HLSL's way of reading in those variables?
