You could be more specific here. Do you need 3d soft for
VR/AR content creation? as ozey6 mentioned here you would go with blender, 3dmax, maya, cinema4d ..and so on.
VR/AR content creation in VR? then u d go with gravity sketch, adobe medium ... and so on.
VR/Ar final presentation? all major game engines again as stated above unity / unreal4 / etc.
Or you plan to learn more lo level stuff? then i guess open gl and so on.
