i''m playing around with a demo to learn OpenGL. one question: if I want to make a level with lots of individual rooms, I''m guessing I have to come up with all the vertices for the walls? right now, I just sketch the room on graphing paper and find all the vertices myself, but this is very time-consuming. My question is do I have to come up with all the vertices myself, or is there a shortcut? thank you in advance for your time I''m a newbie, please don''t hurt me!

I''ve cheated with this before myself... I made some geometry in milkshape3d($20-25)...save the file as a Milkshape ASCII (text)file...(if I remember correctly)...I then copied and pasted the vertices over to another text file that my program read and saved into a buffer (array)...which then acted as a vertex array!!!

Hope that helps
