Once I have my projection matrix setup, and I start my render loop, what are teh minimal steps for inserting objects independently of each other into the scene? Do I need to reset the model-view matrix each time by calling glLoadIdentity()?

Is this correct?

glLoadIdentity();
glTranslatef(x, y, z);
glRotatef(pitch, 1.0, 0.0, 0.0);
glRotatef(yaw, 1.0, 0.0, 0.0);
glRotatef(roll, 0.0, 0.0, 1.0);
glBegin();
.
.
.
glEnd();

thanks,

if i understand right

theres many methods for what u want, one easy method

glMatrixMode( GL_MODELVIEW );
gluLookAt(…)

  • for each object
    glPushMatrix();
    glMultMatrix( objs_orientation );
    draw model { eg glBegin()…glEnd() }
    glPopMatrix();
