Thanks for the quick reply! The machine I am using now
apparently supports only openGL 1.4 (says OpenGL Extensions Viewer) after
updating to the latest driver. Probably this is a crappy Intel thing:-).
Starting the Mandelbrot example leads to the
MessageNotUnderstood: GPGPU>>handleError:
where handleError: is send from
GPGPU>>checkForFBO
checkForFBO
"(adapted from David Fraught's
code) Check for FBO support"
"this is a pretty minimal
check"
| status |
status := ogl extensions includes:
#'GL_EXT_framebuffer_object'.
status ifFalse: [ self handleError:
'FBO is not supported\Try running:\GPUInfo new chkGLSLSupport' withCRs.
]
Clearly, 'GL_EXT_framebuffer_object' is not available
on my system. (handleError: is not implemented in GPGPU, nor is the class
GPUInfo available; maybe these were part of David's code?)

Do you have any information on the versions/settings for
OpenGL and graphics drivers that are required to run this?
It uses features from OpenGL 1.5 so any card
from the last couple of years should run it. Windows shouldn't be an issue, nor
drivers (just make sure they're the latest I guess). It could be that your
machines have crappy integrated graphics - try it on a machine with a recent
discrete card & it should run.
Are you getting any errors BTW
?
