Gah! Texture problem

For some reason, the texture in this code does not properly show. It gets mapped out in a radial pattern, like spokes in a wheel almost. Any ideas? It''s driving me insane.

GLvoid BuildMapList()
{
 int xloop, yloop;
 glLoadIdentity();
 GLfloat floatx, floaty, floatxB, floatyB;
 MapList=glGenLists(1);
 glBindTexture(GL_TEXTURE_2D, texture[0]);
 glNewList(MapList,GL_COMPILE);			// New Compiled box Display List
  //glBegin(GL_QUADS);
  glBegin(GL_LINES);
   for (xloop=1;xloop

Hi !

Not sure, but you''re trying to apply a 2d texture on a terrain, right ?
I guess you should be using glTexCoord2f(floatx, floaty) once per vertex (before each glVertex3f statement).

BTW, you should consider using triangle strips instead of quads.

Reading the code, textures, quads and colars are in commentary so they won't be compiled. I think the right code should be like:


glVertex3f(float(xloop/xyScale),float((yloop+Detail)/xyScale),float(hmap(xloop,yloop+Detail)/zScale));  

glVertex3f(float(xloop/xyScale),float(yloop/xyScale),float(hmap(xloop,yloop)/zScale));          

glVertex3f(float((xloop+Detail)/xyScale),float((yloop+Detail)/xyScale),float(hmap(xloop+Detail,yloop+Detail)/zScale));

glVertex3f(float((xloop+Detail)/xyScale),float(yloop/xyScale),float(hmap(xloop+Detail,yloop)/zScale));

Note that I only use LINES just for wireframe so I may mistake as I don't know to texture them yet.

thanks rod.

I''m not concerned about the performance issues of using quads, This project wont be used for anything off this system.
