Qt3D, Download data buffer
I'm using Qt3D to launch a compute shader. The input of the compute shader is a 2d texture and the output is a matrix with some information computed analizing the texels in the input texture. The output matrix is stored in a shader storage buffer. After that computation, I need the output matrix in cpu to continue with the execution, but I can't find anyway to download the buffer content.
It will also be useful to stop Qt3D execution after the compute shader has finished.
Any idea on how to do this?
