Hi All,
I think the TextRenderer is broken in the rc-4 and rc-5 webstart versions of the jogl library.
If my applet uses http://download.java.net/media/jogl/builds/archive/jsr-231-webstart-current/jogl.jar no text appears, but if I drop back to using rc-3 my text appears fine.
I’ve also noticed that all of the TextRenderer demos on the jogl home page are broken (probably for the same reason)
Hope this helps someone
Stu.
BTW is there somewhere other than this forum where I can post bug reports?
What’s the output of demos.printext.PrintExt?
The new TextRenderer introduced in 1.1.1-rc4 currently assumes VBOs are available. This might not be a good assumption for older graphics cards.
Hi, I’m bumping into this topic but talking about VBO, we may have spotted an error in TextRender code…
Well not an error but it seems that a state is not properly reverted…
We had to call
glBindBuffer(GL.GL_ARRAY_BUFFER_ARB, 0);
just after the end3DRendering.
I don’t have the code right here, but I should I put a bug if I can confirm it?
Thanks
what happens on graphics cards, where VBOs are not available? does it fallback to the old textrenderer?
Yes, please file it if you can confirm it. I actually had that workaround in place but took it out as at least on some graphics cards it seems it isn’t needed. However this is an area where the OpenGL spec seems to be ambiguous. If you can file the bug soon I’ll refer to it in the checkin message fixing it.
Right now it will either silently fail or throw a GLException. It needs to be changed to use normal vertex arrays in this case.
It looks like its a problem with VBO’s not being available. I get javax.media.opengl.GLException: Method “glBindBuffer” not available
This is not an old gfx card but an Mobile Intel® 945 Express Chipset Family which is in the current version of the MacBook.
Stu.
What OS are you running on your MacBook? Could you please download the jogl demos jar files, put jogl-demos.jar on your CLASSPATH and run demos.printext.PrintExt, posting the output?
I can fix the bug without this information, but it would be helpful to know how many configurations out there are affected.
Hi,
Same behaviour on this laptop - I’m running XP SP2, with an Intel 945 as well

A coworker confirmed the “little bug” about VBO state, so I filled the bug ID 323 (quite in a hurry).
Thanks.

Sorry forgot to mention the last output was from a MacBook running WinXP under bootcamp.
This next output is from the macbook running OSX 10.4 where the fonts appear correctly

Will be fixed in tomorrow’s promoted build, 1.1.1-rc6. Also a fallback code path has been added for machines without VBO support.
this might be a very stupid question, but since i cant stop thinking about it, i dare to ask it:
what does the textrenderer use VERTEX buffer objects for?
since it is based mostly on glyphs which are rendered on a texture, shouldnt it use FRAME buffer objects?
The trick is to render each glyph as a textured quad isn’t? So the VBO are welcom to do this.
