Mixing textures and flat shading

Recommended Posts

Hi guys, sorry for the dumb question - i must be missing something simple but I just don't know what. I've managed to get a texture mapped quad on the screen. However, if I then try to draw another shape without a texture nothing gets displayed. If I take the texture out everything is fine. I'm working in orthogonal mode as it's a 2D project i'm gearing up for. My init code contains:
	glEnable(GL_TEXTURE_2D);						glShadeModel(GL_SMOOTH);						glClearColor(0.0f, 0.0f, 0.0f, 0.0f);					glHint(GL_PERSPECTIVE_CORRECTION_HINT, GL_NICEST);			glEnable(GL_BLEND);
	glDisable(GL_DEPTH_TEST);						glBlendFunc(GL_SRC_ALPHA, GL_ONE_MINUS_SRC_ALPHA);

	glTexEnvi(GL_TEXTURE_ENV, GL_TEXTURE_ENV_MODE, GL_REPLACE);

and my drawing code contains:
	glBindTexture(GL_TEXTURE_2D, textures[0]);
	glLoadIdentity();
	glTranslatef(320.0f, 240.0f, 0.0f);
	glRotatef(rtri,0.0f,0.0f,1.0f);
	glColor4f(1, 1, 1, 1);
	glBegin(GL_QUADS);
		glTexCoord2f(1, 1);
		glVertex2f( 100, 100);
		glTexCoord2f(1, 0);
		glVertex2f(100, 0.0f);
		glTexCoord2f(0, 0);
		glVertex2f(0.0f,0.0f);
		glTexCoord2f(0, 1);
		glVertex2f( 0.0f, 100);
	glEnd();

	glBindTexture(GL_TEXTURE_2D, 0);
	glLoadIdentity();
	glTranslatef(320.0f, 240.0f, 0.0f);
	glBegin(GL_TRIANGLES);
		glColor4f(1.0f, 0.0f, 0.0f, 1.0f);
		glVertex3f(0.0f, 100.0f, 0.0f);
		glColor4f(0.0f, 1.0f, 0.0f, 0.5f);
		glVertex3f(-100.0f,-100.0f, 0.0f);
		glColor4f(0.0f, 0.0f, 1.0f, 0.0f);
		glVertex3f( 100.0f,-100.0f, 0.0f);
	glEnd();

Could anyone give me some pointers as to where i'm going wrong please? TIA [Edited by - phantom on November 4, 2005 8:15:25 AM]

I don't see anything wrong with it. Instead of binding a NULL texture have you tried to disable 2d texturing and drawing and the enabling the 2d texture after drawing the quad with no texture ?

Does that work for you ?

Yes! That fixed it, thank you. I didn't realise that I had to disable texturing in order to draw a solid shape - especially if i've selected no texture and specified the colours of the vertices.

Thanks CRACK.
