Hi, i rendered my shadow map with that shaders.
void main( in float4 position : POSITION,
out float4 positionOUT : POSITION,
out float3 lightVector : TEXCOORD0,
uniform float4 lightPosition,
const uniform float4x4 model_view_projection_matrix)
{
positionOUT = mul(model_view_projection_matrix, position);
lightVector = lightPosition.xyz - (position.xyz);
}
void main(
in float4 positionOUT : POSITION,
in float4 lightVector : TEXCOORD0,
out float4 color : COLOR
)
{
float fDepth = dot(lightVector, lightVector);
color = float4(floor(fDepth) / 256.0, frac(fDepth), frac(fDepth), frac(fDepth));
}
