Hey guys.I am not really strong with 3d cartesian geometry et al.I've been trying to get an out put like this
th.d60c149108.jpg

but i end up with this instead
th.c7c7f9385f.jpg

I am not very good with setting them vertex normals too.

these are my texture co-ordinates

CUSTOMVERTEX v[]=
{
{-20.0f, -2.5f, -20.0f, 0.0f, 1.0f, 0.0f, 0.0f, 1.0f, },
{-20.0f, -2.5f, 20.0f, 0.0f, 1.0f, 0.0f, 0.0f, 0.0f,},
{ 20.0f, -2.5f, 20.0f, 0.0f, 1.0f, 0.0f, 1.0f, 0.0f,},
{-20.0f, -2.5f, -20.0f, 0.0f, 1.0f, 0.0f, 0.0f, 1.0f,},
{ 20.0f, -2.5f, 20.0f, 0.0f, 1.0f, 0.0f, 1.0f, 0.0f,},
{ 20.0f, -2.5f, -20.0f, 0.0f, 1.0f, 0.0f, 1.0f, 1.0f,},

};





my CUSTOMVERTEX format is (x, y, z, nx, ny, nz, texel u, texel v)


EDIT:sorry if this question is too dumb.i am a noob..

From the pictures, it appears that you're drawing the quads with the light colored texture in a vertical plane, rather than a horizontal plane. That doesn't have anything to do with your texture coordinates.

You need to either rotate the quads mesh or change the coordinates.

What vertex format you set? The one in second screenshot looks like D3DFVF_XYZRHW.


struct CUSTOMVERTEX{
float x, y, z; // vertex coords
float tx, yx; // texture coords
};

CUSTOMVERTEX v[] = {
{-20, -2.5f, -20, 0, 0}
{ 20, -2.5f, -20, 1, 0}
{-20, -2.5f, 20, 0, 1}
{ 20, -2.5f, 20, 1, 1}};

device->SetFVF(D3DFVF_XYZ | D3DFVF_TEX1); // D3DFVF_XYZ means it's vertex in 3D world, D3DFVF_TEX1 tells you have texture coords
//set texture here
device->DrawPrimitiveUP(D3DPT_TRIANGLESTRIP, 2, v, sizeof(CUSTOMVERTEX));
