OpenGL mode is slow in processing 2.0a4

in Core Library Questions • 1 year ago

I'm working with processing 1.5.1 and 2.0a4, but OpenGL is slow in 2.0a4.

For example, Esfera(OpenGL Example) in 2.0a4 runs slowly and its cpu usage is very high.

But when I reduced number of lines to 1000, it runs fast.

Mac OS X 10.7.2 / Macbook Pro 2.66 / NVidia GT330M

Thought I'd try, and same here...

Same machine (Processor and Graphics Card), but running 10.6.8 ...

1.5.1 = 50fps

2.0.4 = 21fps

EDIT: 20fps with P3D on 2.0.a4 - I notice that the example is set to OPENGL renderer on the OSX distro but P3D on Win...

I'll boot over to my Windows side and test there too...

Yeah, same issue on Win7

1.5.1 = 60fps (Yay Updateable Graphics Drivers!)

2.0.4 = 27fps on P3D (old OpenGL) and OpenGL (new ?)

I think this is probably a non issue by now current svn version of processing-2.0 I found esfera run v. well even with more lines (64 bit linux pretty average graphics card).

Cool... Yeah, I'm sure they know about this and are working it out. I noticed a few open issues around OpenGL already too...

What Revision is the current?

Actually with latest version 9063, I seem to get similar performance issues as stated. I'm pretty sure it was running great at one stage, problem is I'm running a couple of different setups. Esefera is included under subheading performance in the new examples and the no of lines has been doubled, so I am sure performance improvement is anticipated. There are lot of changes still happening, perhaps it was the different quality of the lines that had made the impression.

Hi guys, sorry for the late reply.

As monkstone noted, the OpenGL code in 2.0a4 is quite outdated already in comparison to the latest revisions in the svn :-)

The immediate rendering in P3D was entirely overhauled during the past weeks (see the diff between revisions 8863 and 9063 of PGraphicsOpenGL.java). Performance should be at least comparable with that of the older OPENGL renderer, and substantially faster in many cases.

Still debugging some specific scenarios, but I think that the new P3D will be generally faster. It's going to be available in the next alpha release, 2.0a5.
