problem with jit.gl.render on IMac G5


    Apr 26 2006 | 2:47 pm
    Hello, Jitter-folk,
    I am writing with regard to a problem I'm having on a recently purchased IMac G5 (PPC, NOT intel) 2.1GHz 21" machine.
    I'm running a previously created patch that worked fine on a Powerbook G4 1GHz / 1.5GB RAM.
    Now I'm trying to work on it on a new IMac G5 2.1GHz / 1.5 GB RAM, ATI Radeon x600 XT
    Both machines have Jitter 1.5.2 installed. With the Powerbook test-run, all works fine, > jit.gl.render: building GL on window "Sonic_Subway_Map"... ... commences and the project is OK.
    With the new IMac test-run, I get: > jit.gl.render: building GL on window "Sonic_Subway_Map"...
    then >jit.gl.texture: setting texture target.: GL Error: Invalid value jit.gl.texture: setting subteximage during submission.: GL Error: Invalid operation
    Since nothing has changed besides my machine here, I'm confused. I've sent this "isolated problem" patch to others and it works on their powerbooks:
    I can send the image as a personal e-mail attachment to anybody who is able to help since I'm not sure how the list feels about attachments. Perhaps someone knows the answer to this mystery? Time is of the essence as this is going to be part of an installation that begins in a week and a half! Cheers, Jim Briggs

      I had this problem recently, and I solved it by changing the dimensions of my texture images. I don't know what exactly is the problem, but I guess it has something to do with proportions or multiples of 2 pixels width/high... So not exactly sure, but that 'did' solve it for me. If someone can shed more light on this, i'd be happy to know this as well...
      regards, brecht

      Hey,
      could you send me the file you use in this patch ? Interested to check what the problem can be...
      grtz, Brecht.

      I just located my problem and it was with quicktime, actually. I did a re-install up to the latest version and it solved everything.
      I noticed when going back to the help that the movies either weren't playing or were acting funny when I loaded them up in help.
      Nice to know it wasn't my new machine or max inabilities. ;)
      I can still send the image if you'd like, though.
      Cheers, Jim

      Well... I guess that wont be necessary :) Good to hear you managed to solve it. I did have the problem with the jit.gl.texture objects when loading in certain files of certain dimensions which seems to be related to the hardware.
