accurately placing 3D objects.
Feb 18th, 2008, 2:38pm  
I'm fairly new to processing so there's a fair chance I'm missing a few things here.

What I'm trying to do is lay out a grid of boxes with pixel accuracy. From what I can follow the only way to decide exactly where a box() goes is to translate() to the centre of the box's desired location. Ok, cumbersome but I can live with that however if the width/height of the box is uneven, how the hell am I meant to specify the exact centre? Can I use floating numbers? Won't they just be rounded?

In 3D you can place them using floats, and no rounding occurs. However unless you use smooth(); the on-screen image will be limited to a whole pixel result.

Even with smooth() you may not be able to have even looking spacing.

I might just multiply everything by 10 and zoom the camera out, going to make for some crazy numbers but at least everything will be round.

So the translate/box method is the 'approved' box placement method?

The numbers might be round, but it'll still look exactly the same.

There is no "approved" method, it's just the easiest was of doing it.
