All I did was load two textures and then modify this:

// Process Each Trianglefor (int loop_m = 0; loop_m < numtriangles; loop_m++){glBegin(GL_TRIANGLES);x_m = sector1.triangle[loop_m].vertex[0].x;y_m = sector1.triangle[loop_m].vertex[0].y;z_m = sector1.triangle[loop_m].vertex[0].z;u_m = sector1.triangle[loop_m].vertex[0].u;v_m = sector1.triangle[loop_m].vertex[0].v;glTexCoord2f(u_m,v_m); glVertex3f(x_m,y_m,z_m);x_m = sector1.triangle[loop_m].vertex[1].x;y_m = sector1.triangle[loop_m].vertex[1].y;z_m = sector1.triangle[loop_m].vertex[1].z;u_m = sector1.triangle[loop_m].vertex[1].u;v_m = sector1.triangle[loop_m].vertex[1].v;glTexCoord2f(u_m,v_m); glVertex3f(x_m,y_m,z_m);x_m = sector1.triangle[loop_m].vertex[2].x;y_m = sector1.triangle[loop_m].vertex[2].y;z_m = sector1.triangle[loop_m].vertex[2].z;u_m = sector1.triangle[loop_m].vertex[2].u;v_m = sector1.triangle[loop_m].vertex[2].v;glTexCoord2f(u_m,v_m); glVertex3f(x_m,y_m,z_m);glEnd();}  

To:

// Process Each Triangle
for (int loop_m = 0; loop_m < numtriangles; loop_m++)
{
glBegin(GL_TRIANGLES);
x_m = sector1.triangle[loop_m].vertex[0].x;
y_m = sector1.triangle[loop_m].vertex[0].y;
z_m = sector1.triangle[loop_m].vertex[0].z;
u_m = sector1.triangle[loop_m].vertex[0].u;
v_m = sector1.triangle[loop_m].vertex[0].v;
glTexCoord2f(u_m,v_m); glVertex3f(x_m,y_m,z_m);
glEnd();

glBegin(GL_TRIANGLES);
x_m = sector1.triangle[loop_m].vertex[1].x;
y_m = sector1.triangle[loop_m].vertex[1].y;
z_m = sector1.triangle[loop_m].vertex[1].z;
u_m = sector1.triangle[loop_m].vertex[1].u;
v_m = sector1.triangle[loop_m].vertex[1].v;
glTexCoord2f(u_m,v_m); glVertex3f(x_m,y_m,z_m);
glEnd();

glBegin(GL_TRIANGLES);
x_m = sector1.triangle[loop_m].vertex[2].x;
y_m = sector1.triangle[loop_m].vertex[2].y;
z_m = sector1.triangle[loop_m].vertex[2].z;
u_m = sector1.triangle[loop_m].vertex[2].u;
v_m = sector1.triangle[loop_m].vertex[2].v;
glTexCoord2f(u_m,v_m); glVertex3f(x_m,y_m,z_m);
glEnd();

}




Mr Bugg

you''ve got your problem right there...

glBegin( GL_TRIANGLES );
...
glTexCoorf( u,v );
glVertex( x, y, z );
glEnd();

you send only one vertex per triangle.

there should be 3 * N vertices where N is number of triangles to draw.

about your ogirinal question.

If you''re using original dataformat from NeHe''s code just add another info to file:
to every triangle add texture no:

so you have :
...
u, v
x, y, z
tex_id
...

then have your drawing code change like this:


for ( int i=0; i glBindTexture( triangle.tex_id );
glBegin( GL_TRIANGLES );
// draw ALL 3 vertices of this triangle ( 3x glTexCoord() + 3x glVertex() )
glEnd();
}

befire you start drawing your stuff make shure you load textures in right tex_id''s and you enable texturing


hope this helps....


PS : this code is just a sample (it won''t compile )
PS2 : This is probably the lowest way to draw your level

There are more worlds than the one that you hold in your hand...
