Unfolding overview+context example difficulties

Unfolding overview+context example difficulties

in Contributed Library Questions • 1 year ago

Hi,

can anyone pinpoint why this example isn't working in Processing ( i have added unfolding library and openGl) but no joy.. I'm getting this error:

frame buffer is incomplete (gl_framebuffer_unsupported_ext)

is it my machine?

Just tested again with latest GLGraphics 1.0 and works for me.

This seems to be some incompabilities of your JRE and GLGraphics. Might be related to the native libraries we provide with the Unfolding dist. What system are you using? Which Java version? Which Processing?

That's Windows Vista or 7, I suppose? Unfortunately I don't have access to a Windows machine, at the moment. But you might need to try some of the suggestions made here:

http://forum.processing.org/topic/processing-opengl-and-windows-x64

Also check, if the OpenGL and GLGraphics examples work. This might not be an Unfolding problem.

yup, windows 7. just tried loading up the space-junk from opengl examples folder -works fine...

however still getting:

frame buffer is incomplete (gl_framebuffer_unsupported_ext)

when i try running overview+context example.

Are you trying it on a mac?

Its working now: took out 'GLConstants.GLGRAPHICS' from size parameters in setup .However, console reads:'no rotation possible (without openGL)' though it all seems to work fine!

Incidentally, anyone know how i would add my own sketch to this code, how would i link it in so i can use it as in this example?

Glad to hear you have it working. Removing that parameter swtiches the rendering to Processing's 2D mode. It might be a bit slower, as you are not using OpenGL/GLGraphics, now.
(So, for others reading this thread: We suggest keeping that parameter.)
