Texture Problem.

OpenGL OpenGL: Basic Coding
1

I have made a textured cube, and a colored (gradient) triangle. when I run my program, It shows the texture as the incorrect color, and makes the triangle a very dark color…

I tried to split the two into two different ints, and then added them like so:

int Display(GLvoid)
{
DisplayCube();
DisplayTri();
}

Anyone help please.

you will need to provide more information, are you using lighting? fog?

Ok, sorry, No no fog. Just a simple Textured 3D Cube using

glTexCoord2f(0.0f, 0.0f);
glVertex3f(-1.0f, -1.0f, -1.0f);

and a simple 3D triangle with gradient colors using:

glColor3f(1.0f,0.0f,0.0f);
glVertex3f( 0.0f, 1.0f, 0.0f);
glColor3f(0.0f,1.0f,0.0f);
glVertex3f(-1.0f,-1.0f, 1.0f);
glColor3f(0.0f,0.0f,1.0f);

You get the general Idea :slight_smile: I switched around the Bind Texture and that didn’t help. here is the full display code:

int Draw(GLvoid)
{
glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);
glLoadIdentity();
glTranslatef(-1.5f,0.0f,-6.0f);
glBindTexture(GL_TEXTURE_2D, texture[filter]);
glBegin(GL_QUADS);
glNormal3f( 0.0f, 0.0f, 1.0f);
glTexCoord2f(0.0f, 0.0f);
glVertex3f(-1.0f, -1.0f, 1.0f);
glTexCoord2f(1.0f, 0.0f);
glVertex3f( 1.0f, -1.0f, 1.0f);
glTexCoord2f(1.0f, 1.0f);
glVertex3f( 1.0f, 1.0f, 1.0f);
glTexCoord2f(0.0f, 1.0f);
glVertex3f(-1.0f, 1.0f, 1.0f);
glNormal3f( 0.0f, 0.0f,-1.0f);
glTexCoord2f(1.0f, 0.0f);
glVertex3f(-1.0f, -1.0f, -1.0f);
glTexCoord2f(1.0f, 1.0f);
glVertex3f(-1.0f, 1.0f, -1.0f);
glTexCoord2f(0.0f, 1.0f);
glVertex3f( 1.0f, 1.0f, -1.0f);
glTexCoord2f(0.0f, 0.0f);
glVertex3f( 1.0f, -1.0f, -1.0f);

disable texturing before rendering the triangle: glDisable(GL_TEXTURE_2D)

Thanks dude, I was wondering if there was a function of such type ^^ I don’t have the GL library printed out yet, I’m murdering both my ink and my deskjet. ^^
But thanks * 1000^6/2.5

I still need to purchase some of them thar good books. :slight_smile:
