OpenGL Multitexture Quick Tutorial
- Configuring up a given texture unit: glActiveTextureARB(GL_TEXTURE1_ARB); glBindTexture(GL_TEXTURE_2D, texObject); glTexImage2D(GL_TEXTURE_2D, …); glTexParameterfv(GL_TEXTURE_2D, …); glTexEnvfv(GL_TEXTURE_ENV, …); glTexGenfv(GL_S, …); glMatrixMode(GL_TEXTURE); glLoadIdentity();
- Setting texture coordinates for a vertex: glMultiTexCoord4f(GL_TEXTURE0_ARB, s0, t0, r0 ,q0); glMultiTexCoord2f(GL_TEXTURE1_ARB, s1, t1); glMultiTexCoord3f(GL_TEXTURE2_ARB, s2, t2, r2); glVertex3f(x, y, z);
