[Interest] [Qt3D] Use already available OpenGL buffer for geometry

[Nicolás Ulrich]

Hi,

I was wondering if there's a way to use a buffer I already have in the
GPU memory for my geometry? I want to avoid copying it to the CPU and
then having Qt3D uploading it again (it's for  viewing data being
computed/updated constantly with CUDA).

I have it working with "raw" OpenGL but I miss all the nice things
already available in Qt3D (thanks!!).
