gpgpu - OpenGL 4.0 GPU Draw Feature? -


in wikipedia , other sources' description of opengl 4.0 read feature:

drawing of data generated opengl or external apis such opencl, without cpu intervention.

what referring to?

edit:

seems must referring draw_indirect believe somehow extends draw phase include feedback shader programs or programs interop (opencl/cuda basically) looks if there few caveats , tricks getting calls keep staying on gpu extended amount of time past second run should possible.

if can provide more info on using draw commands without cpu or can describe draw indirect better, please feel free so. appreciated.

i believe may refering gl_arb_draw_indirect functionality allows opengl source drawarrays or drawelements parameters gpu buffer object, can filled opengl or opencl.

if i'm not mistaken, it's included in core opengl 4.
