zbuffer problems?
Author
I'm running slimdx and I have a shader that runs. And for some reason the zbuffer is not appearing to work. I have set zenable to true. Is there some inherint problem in slimdx that stops it from performing standard zbuffer testing? So do I need to perform zbuffer testing in my hlsl program?
Firstly make sure zwriteenable and zfunc are also set appropriately.
You don't need to do anything special in the hlsl.

I think I found the problem. Its in the shader. It calcs on a float4 which is causing trouble with the w coordinate in the vertex. Can anyone help me figure out how to work on only a float3 instead of a float4, I just get errors.
float4x4 wvp;float4x4 w;float4x4 v;float3 eyedir;float3 lightdir;float4 ambient;float4 linecolor;texture tex;sampler samp = sampler_state { texture = (tex); };struct vmI{ float4 p : POSITION0; float3 n : NORMAL0; float4 c : COLOR0; float2 t : TEXCOORD0;};struct vmO{ float4 p : POSITION0; float3 n : TEXCOORD1; float4 c : COLOR0; float2 t : TEXCOORD0;};struct pmI{ float3 n : TEXCOORD1; float4 c : COLOR0; float2 t : TEXCOORD0;};vmO VShader(vmI i){ vmO o; o.p = mul(i.p, wvp);//position o.n = mul(i.n, w);//mul(i.n0, view);//normal o.c = i.c;//material diffuse o.t = i.t;//texture coordinate return o;}float4 PShader(pmI i) : COLOR{ //normalize input float3 ld = normalize(lightdir); float3 nd = normalize(i.n); float3 ed = normalize(eyedir); //calc diffuse component //float3 ref = ld - nd + nd; //float4 litpow = dot(ref, ed); float4 litpow = dot(nd, ld); float4 spec = litpow;// * i.c;// spec += ambient; //return the color composition float4 o = spec; o.a = 1; //float4 s = tex2D(samp, i.t); //o *= s; return o;}technique Shader{ pass p0{ //BlendOp=Subtract; //SrcBlend=ONE; //DestBlend=DESTCOLOR; //CullMode = CCW; //ZEnable = true; //ZWriteEnable = true; //Lighting = true; VertexShader = compile vs_2_0 VShader(); PixelShader = compile ps_2_0 PShader(); } }This topic is closed to new replies.
