Problem when texturing triangles using glVertexPointer()
- by tigrou
I'm having a problem for displaying a single quad, here is how i do :
float tex_coord[] =
{
0.0, 0.0,
0.0, 1.0,
1.0, 1.0,
1.0, 1.0,
1.0, 0.0,
0.0, 0.0
}; //how many coords should i give ?
int indexes[] =
{
3, 2, 0, 0, 1, 3
}
float vertexes[] =
{
-37, 0, 30,
-38, 0, 29,
-41, 0, 32,
-42, 0, 31
}
glEnableClientState(GL_TEXTURE_COORD_ARRAY);
glEnableClientState(GL_VERTEX_ARRAY);
glVertexPointer(3, GL_FLOAT, 0, vertexes);
glTexCoordPointer(2, GL_FLOAT, 0, tex_coord);
glDrawElements(GL_TRIANGLES, 2, GL_UNSIGNED_INT, indices);
glDisableClientState(GL_VERTEX_ARRAY);
glDisableClientState(GL_TEXTURE_COORD_ARRAY);
The result :
(with 2 triangles)
(with 4 triangles)
