Updating buffer data frame by frame

  • I know i can generate custom geometry data in qt3d using QBufferDataGenerator. Is it feasible to do this on a frame-by-frame basis?

    Whenever i call do something like this:


    the data is only updated the first time it is called. Is there any way to invalidate the current vertex buffer data so it updates itself with the new data?

    I want to make a particle system (CPU) which would require the vertex buffer data be updated each frame. How would I implement something like that?
