Hi folks,

I have a big problem understanding the decision of making the pos. y-axis pointing downwards. This makes the whole thing totally counterintuitive for me even if this is a correct right-hand system. I've never used a 3D-creating app that turns the Y-axis this way and I think this makes the jpct engine unnecessary complicated.

Nevertheless...

I used the "Box-Primitive" code snipped from the wiki and applied a texture to it. The texture is placed upside-down. A texture applied to the bottom-part of the Box appears on the top of the box. So the "lower"-points are the upper ones, or what? Okay, so I tried to rotate my cam around the direction-axis by setting the up-vector from (0.0f, -1.0f, 0.0f) to (0.0f, +1.0f, 0.0f), but nothing happend.

I'm really confused... Can someone please give me a hint, what I don't understand at this topic?

Ciao

Edit: Setting the Y-axis pointing downwards is like climbing a 2 miles high mountain by digging a 2 miles deep hole!
