Thread: OpenGL Dual Textures

In the OpenGL tutorials on nehe.gamedev.net they don't tell you how to load multiple textures. I've been experimenting with the original code to do this but I just can't figure out how to do this yet. Anybody know?

Umm I'm assuiming you're doing lesson 4 or 5 or whatever the first texture example is. If that's the case they do tell you how to load multiple textures. I'm assuimg you have the same setup as nehe. create a global GLuint texture array, and call the LoadTexture function for each element of that array. When you go to draw, call glBindTexture(GL_TEXTURE_2D, texture[x]); before you draw the polygon and make sure it is outside of the glBegin/glEnd block;

Code:

GLuint texture[2];  //storage for 2 textures

...
//in your initialize function (InitGL() in nehe)
texture[0] = LoadTextures("crap.bmp"); //this function name may be different than nehe's but they are fundamentally the same
texture[1] = LoadTextures("bitmap.bmp");
...
//in your drawglscene function (DrawGLScene() in nehe)
int DrawGLScene(GLvoid)									// Here's Where We Do All The Drawing
{
	glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);	// Clear Screen And Depth Buffer
	glLoadIdentity();									// Reset The Current Modelview Matrix
	gluLookAt(0.0f, 0.0f, 0.0f, 0.0f, 0.0f, -150.0f, 0.0f, 1.0f, 0.0f);
	

	glPushMatrix();
	glTranslatef(-20.0f, 0.0f, 0.0f);
	glBindTexture(GL_TEXTURE_2D, texture[0]);	//MAKES THIS OUR CURRENT TEXTURE
	glBegin(GL_QUADS);
	glTexCoord2f(0.0f, 0.0f);	glVertex3f(-15.0f, -5, -75.0f);
	glTexCoord2f(1.0f, 0.0f);	glVertex3f(15.0, -5, -75.0f);
	glTexCoord2f(1.0f, 1.0f);	glVertex3f(15.0, 5, -75);
	glTexCoord2f(-1.0f, 1.0f);	glVertex3f(-15.0f, 5, -75);
	glEnd();
	glPopMatrix();

	glPushMatrix();
	glBindTexture(GL_TEXTURE_2D, texture[1]);
	glBegin(GL_QUADS);
	glTranslatef(20.0f, 0.0f, 0.0f);
	glTexCoord2f(0.0f, 0.0f);	glVertex3f(-15.0f, -5, -75.0f);
	glTexCoord2f(1.0f, 0.0f);	glVertex3f(15.0, -5, -75.0f);
	glTexCoord2f(1.0f, 1.0f);	glVertex3f(15.0, 5, -75);
	glTexCoord2f(-1.0f, 1.0f);	glVertex3f(-15.0f, 5, -75);
	glEnd();


	return TRUE;										// Everything Went OK
}

Thank you so much.

Didn't work, here's the source:

?

here is that example, sorry it took so long
