Index/Vertex Buffer Texturing Woes
Author
Can anyone explain to me why this is not working...?
sudo code...
int renderSize = 4, indexSize = 6;
Vector3 vertex[renderSize*3] = {
-300,300,0,
0,0,0,
0,0,1,
300,300,0,
1,0,0,
0,0,1,
-300,-300,0,
0,1,0,
0,0,1,
300,-300,0,
1,1,0,
0,0,1, };
Where it is a buffer of position, texcoord, and normals.
unsigned short index[indexSize] = {0,1,2,3,2,1};
LPDIRECT3DVERTEXBUFFER9 vBuffer;
LPDIRECT3DINDEXBUFFER9 iBuffer;
graphics->CreateVertexBuffer(renderSize*sizeof(Vector3)*3,0,0,D3DPOOL_MANAGED, &vBuffer,0);
void *pVoid = NULL;
vBuffer->Lock(0,0,&pVoid,0);
memcpy(pVoid,vertices,renderSize*sizeof(Vector3)*3);
vBuffer->Unlock();
graphics->CreateIndexBuffer(indexSize*sizeof(unsigned short),0,D3DFMT_INDEX16,D3DPOOL_MANAGED,&iBuffer,0);
unsigned short *ind = NULL;
iBuffer->Lock(0,0,(void**)&indices,0);
memcpy(ind,indices,indexSize*sizeof(unsigned short));
iBuffer->Unlock();
And then the render code...
graphics->SetStreamSource(0,vBuffer,0,sizeof(Vector3)*3);
graphics->SetIndices(iBuffer);
graphics->DrawIndexedPrimitive(D3DPT_TRIANGLELIST, 0,0, renderSize,0,6);
Right now when it textures it looks like a solid color from my texture image...
Thanks,
John
Do you have a 3D texture? You are providing 3 texture coordinates per vertex whereas two would do for 2D textures. What's your vertex declaration? Did the texture image load correctly?

I use three coordinates because I am lazy. Here is my shader:
//External Variablesuniform extern float4x4 wvp;uniform extern texture tex;uniform extern float4 diffuse = {1,1,1,1};sampler TexS = sampler_state{ Texture = <tex>; MinFilter = LINEAR; MagFilter = LINEAR; AddressU = WRAP; AddressV = WRAP;};struct InputVS{; float3 posL: POSITION0; float3 tex: TEXCOORD0; float3 norm: NORMAL0;};struct OutputVS{ float4 posH: POSITION0; float2 tex: TEXCOORD0;};OutputVS TransformVS(InputVS inVS){ OutputVS outVS = (OutputVS)0; outVS.posH = mul(float4(inVS.posL, 1.0f), wvp); outVS.tex = inVS.tex; return outVS;}float4 BasicPS(float2 tex0: TEXCOORD0):COLOR{ return tex2D(TexS, tex0) * diffuse;}technique BasicEffect{ pass P0 { vertexShader = compile vs_2_0 TransformVS(); pixelShader = compile ps_2_0 BasicPS(); }}

Ha...I just solved it... I had my vertex format set to pos, normal, texcoord instead of pos, texcoord, normal... I just wasted three days over that mistake...
