Backface Culling Question

I'm trying to render a cup shape using sio2 , but only the frontmost mesh faces are being rendered and the "inside back face" of the cup is invisible?

I tried to enable double sided mesh face rendering in Blender, but I still cant get part of the cup to appear.

Also what is the easiest way to detect when object hits the cup?

Your help is greatly appreciated.

Cheers.

Try putting this in your GL code:

glDisable(GL_CULL_FACE);


-j

Bingo! That did the trick. Thanks a lot meteor.

No worries :-)

Actually you can also use the "twosided" mode, that will render both front & back polygon, this is ideal in the case that your geometry have some alpha....

sio2interactive , thanks for your help. You said "Actually you can also use the "twosided" mode "...

I was wondering how this can be achieved?

Thanks.

Check the tutorial04 video, Im using "twoside" on the leaf of the palm tree in addition with "translucency" (alpha level in GL) in order to adjust them and to get rid of the blending mode "Value".

Cool, thanks sio2interactive.
