P3D elaboration
Apr 2nd, 2008, 1:03am  
I've recently started learning OpenGL to get into 3D graphics a bit, and I want to try out some of the stuff I've learned in  Processing. However, I notice there is both an OpenGL renderer and P3D. What is P3D? I couldn't find ANY information on it in the website, or even Google. I thought it might stand for PGraphics 3D or Points3D, but again, neither of these turned up very good results.

Can someone explain to me what P3D is and why I should / shouldn't use it over OpenGL for 3D graphics?

No, you got it right: PGraphics3D.

Processing 3D rendering options (You can, of course, use them for 2D, but they just CAN go 3D):

PGraphics: It's 100% java, no platform-specific code. Very light, so people in a webpage won't even notice they downloaded it. However, the graphics card doesn't do the integrated acceleration, but its still amazingly fast. The developers say it's "innacurate, but fast".

OpengL: can do hardware acceleration, and can therefore get some really pretty results (smoothing is pretty great), but some people's graphics cards can't handle it (especially if they have a broken driver). Also, it requires ~ 300 kb of extra plugin to get it to work, so users in a browser will have to wait just a little bit longer for it to start up.

2D rendering options:

P2D: Doesn't exist yet. Ignore it.

Java2D: The current default renderer, really high quality rendering but really slow Sad

Interesting. Thanks for the quick, succinct reply. Is P3D something that was made specifically for/with Processing? I can't seem to find any information on PGraphics for Java outside of its context within the Processing community.

P3D was written specifically for Processing as part of the development.
