Pixel Shader Issues :
- by Morphex
I have issues with a pixel shader, my issue is mostly that I get nothing draw on the screen.
float4x4 MVP;
// TODO: add effect parameters here.
struct VertexShaderInput
{
float4 Position : POSITION;
float4 normal : NORMAL;
float2 TEXCOORD : TEXCOORD;
};
struct VertexShaderOutput
{
float4 Position : POSITION;
};
VertexShaderOutput VertexShaderFunction(VertexShaderInput input)
{
input.Position.w = 0;
VertexShaderOutput output;
output.Position = mul(input.Position, MVP);
// TODO: add your vertex shader code here.
return output;
}
float4 PixelShaderFunction(VertexShaderOutput input) : SV_TARGET
{
return float4(1, 0, 0, 1);
}
technique
{
pass
{
Profile = 11.0;
VertexShader = VertexShaderFunction;
PixelShader = PixelShaderFunction;
}
}
My matrix is calculated like this :
Matrix MVP = Matrix.Multiply(Matrix.Multiply(Matrix.Identity, Matrix.LookAtLH(new Vector3(-10, 10, -10), new Vector3(0), new Vector3(0, 1, -0))), Camera.Projection);
VoxelEffect.Parameters["MVP"].SetValue(MVP);
Visual Studio Graphics Debug shows me that my vertex shader is actually working, but not the PixelShader. I striped the Shader to the bare minimums so that I was sure the shader was correct.
But why is my screen still black?
