* This class object manages a single asynchronous request to animate vertices
|
|
* on a GeomVertexData object. 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.
