from panda3d.core import AnimateVerticesRequest
This class object manages a single asynchronous request to animate vertices on a
GeomVertexDataobject. animate_vertices will be called with force=true (i.e. blocking) in a sub-thread (if threading is available). No result is stored or returned from this object. It is expected that the result will be cached and available for immediate use later during rendering. Thus it is important that the main thread block while these requests are being run (presumably on multiple CPUs/cores), to ensure that the data has been computed by the time it’s needed.
