[osg-users] Read back data from a storage buffer object

[Luca Bianconi]

Hi all,
for an university project I'm trying to set up a compute shader to execute some computation writing results to a shader storage buffer object.
I tried to run a trivial shader code where the data passed to the shader is a float array of 10 elements initialiazed at 1. At execution time one element, for example position 0, is changed to another value.
I don't know to read back data from ssbo into my application code where I need the data computed by the shader.
I'm pretty sure the shader is correctly executed and the ssbo correctly passed to it.
... 

Thank you!

Cheers,
Luca
