GPU "hello world"

jamesbowman

Hi,

I'm trying to write a benchmark for GPU performance on a VOXL 2 (voxl-suite 1.3.5)

So far I've not been able to get a hardware-accelerated OpenGL context.

Is there a "hello world" example that draws something on the GPU and reads the resulting image?

This package

looked promising, but when I run it I only get a software-rendering context.

Or a similar OpenCL tiny app? (I tried "hellocl.zip" mentioned in another thread, and it doesn't find any hardware, as does "clinfo").

Thanks,
James.
