jit.gl.render problem

May 24, 2006 | 1:45 pm

Dear all, I have a problem with jit.gl.render.
I’m using MaxMSP 4.5.5. and Jitter 1.5.2. (demo mode) on Windows XP.

If I link a jit.noise (or something else) to a jit.pwindow everything is ok, but if I link jit.noise to a "jit.gl.render name" and I create a pwindow "name", it doesn’t work.

That’s the patch that explain the problem:

Where I am mistaking?

Your patch works here, on OS X 10.4.6. Check the jitter list archives
for Joshua Kit Claytons recommendation for PC drivers. I believe he
recommends the latest ATI Catalyst drivers.

Thank you Vade.
But I can’t find anything about ATI drivers. I try to install ATI Catalyst from here:

http://download.freenet.de/archiv_a/ati_catalyst_treibe r_w2k-xp_5566.html
without success.

I’m using a Dell Latitude laptop with a Mobility Radeon X300… is this of aid?

Thx :)

I have noticed that the example patch "jitter-examples/render/jit.gl.render-over-movie.pat" also doesn’t work.
I can view the rendering (from jit.slide) and I can heard the audio from the .avi that I imported. But I can see it.

No error in the Max Window.

Is it maybe a Windows Jitter bug?
Or is it just a problem of my video card maybe?

Bruno

Honestly, I dont know – I dont own a PC so I dont deal with
conflicting/odd driver issues. Maybe *search* the forums, or email
support@cycling74.com for help.

Andrew B. from Cycling74 told me this is a bug, and that he will try to fix it on the next version of Jitter.

Yes, thanks for the report. I believe it arises from a similar
problem as Peter Nyboer’s recent glreadpixels problem. A workaround
for this problem would be to render a videoplane instead of using the
draw_pixels method.
