Code Snippet: Clipping Planes in Shader [HLSL]

In the XNA 4.0 we dont have anymore the Fixed function that let us specify a clipping plane. Now we have to do this in shaders =P. In this post i will show how to do this !

The following code shows how to implement ONE clipping plane in Projection Space. (same as the fixed pipeline)

If you want more than one plane, just use the Y,Z,W coordinates from the clipping variable to put the others values. If you want to use the plane in World or View space, just make the “dot” with the position in the right space.

The theory for this is simple. The dot operation evaluates the plane equation and the result give us in what side of the plane the position is. For more info check this.

float4x4 WVP;
float4 clippingPlane;
bool isClip;

Texture diffuse;
sampler DiffuseSampler = sampler_state
texture =  ;
magfilter = ANISOTROPIC;
minfilter = ANISOTROPIC;
mipfilter = LINEAR;
AddressU = wrap;
AddressV = wrap;

struct VertexShaderInput
float3 Position : POSITION0;
float4 texturecoord :  TEXCOORD0;

struct VertexShaderOutput
float4 Position : POSITION0;
float4 texturecoord :  TEXCOORD0;
float4 clipping :  TEXCOORD1;

VertexShaderOutput VertexShaderFunction(VertexShaderInput input)
VertexShaderOutput output;
output.Position = mul(float4(input.Position,1), WVP);
output.texturecoord = input.texturecoord;
output.clipping = 0;
float4 clp = output.Position;
output.clipping.x = dot(clp,clippingPlane) ;
return output;

float4 PixelShaderFunction(VertexShaderOutput input) : COLOR0

return tex2D(DiffuseSampler, input.texturecoord);

technique Technique1
pass Pass1
VertexShader = compile vs_2_0 VertexShaderFunction();
PixelShader = compile ps_2_0 PixelShaderFunction();

    Yesterday, while I was at work, my cousin stole my apple ipad and tested to see if it can survive a twenty five foot drop, just so she can be a youtube sensation. My iPad is now destroyed and she has 83 views. I know this is totally off topic but I had to share it with someone!

    Your headset ended up being because breathtaking like inside picture. That it arrived quickly. I’d suggest using a towel above each and every coating while you press they off w / any steam iron. It doesn’t vapor out among only a steamer. Their iron is important. It is very fragile, so if you don’t trust your self with the towel and/or steam iron, then need that to a certified. Awesome appear.

    Your headset ended up being just as breathtaking just as in photo. They arrived promptly. I’d recommend utilizing a towel during every layer while you push that out w / your steam iron. It does not steam outside using merely a steamer. On iron is appropriate. It is very fragile, so if you do not trust your self aided by the towel and steam iron, well choose they up to a certified. Stunning seem.

    Sorts of write-up Think carefully about the sort of ship you usually get. In the event you tend to get hold of mainly regular bigger envelopes throughout the post then you don’t need to to decide on a huge and often dearer style. In the event you frequently receive opportunities throughout the place it can be a decent investment for you to opt for a safe and sound mailbox with a strong container on the other hand.
