How do you put several separated texture mappings on a single square? Waldoo Edited by - waldoo on January 29, 2002 2:00:52 AM

  glActiveTexture(GL_TEXTURE0); // activate first textuer unitglBindTexture(GL_TEXTURE_2D, tex0); // bind texture to first unitglActiveTexture(GL_TEXTURE1); // activate second texture unitglBindTexture(GL_TEXTURE_2D, tex1); // bind texture to second unit

Then you need to specify texture coordinates for both units.

  glBegin(GL_QUADS);glMultiTexCoord2f(GL_TEXTURE0, 0, 0); // coordinates for first textureglMultiTexCoord2f(GL_TEXTURE1, 0, 0); // coordinates for second textureglVertex2f(...); // first vertex... // and so on, for each vertexglEnd();

Is it really that simple? That''s all? No initialisation code? Nothing?

Cool

sorry to ruin your dream.. but there IS init code.. and quite ugly one.. Look at tutorial 22... it''s all there...

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

You should never let your fears become the boundaries of your dreams.

I didnt mean that. What I mean is several separated pictures on a square. A picture of anything on each corner (4 pictures).

Split your geometry in 4 sub-squares and bind a different texture for each sub-square.
