Ive drawn a dinner table and coffee table using commands glTranslate glRotate gluCylinder gluDisk etc.... and they look ok, but if i want to alter the first drawing i.e. the dinner table, it alters all the co-ordinates of everything ive drawn afterward... This is due to the glTranslate''s being linked to each other... What command can i use to prevent this from happening? Thanks for any help Lee

code for the above question......

int GlassFurniture (GLvoid)
{
///////////////DRAW DINING TABLE//////////////
glEnable(GL_TEXTURE_GEN_S);
glEnable(GL_TEXTURE_GEN_T);


glBindTexture(GL_TEXTURE_2D, texture[13]);

glRotatef(90.0f,1.0f,0.0f,0.0f);
gluCylinder(quadratic,0.03f,0.03f,1.5f,3,1);
glEnable(GL_BLEND);
glBindTexture(GL_TEXTURE_2D, texture[3]);
gluDisk(quadratic,0.0f,1.0f,32,1);

Use glPushMatrix()/glPopMatrix(). To be more specific, call glPushMatrix(), draw the dining table, call glPopMatrix, then glPushMatrix again, draw the coffee table, then glPopMatrix.

Thanks Myopic...ill give it a go.

YEP...works perfectly..thanks a lot.
