[NOT A BUG] Modal timing / watching inside Blender while running in VR about source

[PyrApple]

Dear ptarbiz,

The issue section is usually reserved to issues / bugs noticed while using the code or potential side-devs that may interest the community and be integrated in the main code later.

For individual questions, please use the mailing list [email protected].

Meanwhile, your code is bpy / addon oriented (blender animation, mesh edit, etc.) while BlenderVR is bge (blender game engine), hence it'll not run as is in BlenderVR. That being said, would you mind giving us some details about what you're trying to achieve, if somehow we may be of any help there?

Thank you very much for the instructions.
I am trying to update a blender file using modal timer function. The blender file is constantly watching a particular folder for new pointcloud files to import . As soon the new shape is imported , the existing one gets deleted and all the objects would get aligned to the new geometry. In this way as soon as we manupulate any landscape's sand model (by hand ), the kinect collects the new info, and writes the .ply to the folder and blender updates the terrain info.
Currently everything works perfectly when i submit run script button in blender. My ultimate goal is to project all these in DK2 thats why i am trying to find a way to translate this code for VR.

To project that in DK2, you'll have two solutions:

1. stick to your .ply write / blender-bpy-based framework and use Dalai's Virtual Reality Viewport implementation, or
2. send kinect data to Python for real-time mesh modification in the Blender Game Engine (I'm working on such thing, based on libfreenect2.

Thank you,

I have tried the first option but it did not work in Win 64 as indicated in
their descriptions.
The second is not an applicable one for us since the point files and
rasters are generated by GRASS GIS. We need that connection because GRASS
is in charge of all the geospatial analysis.
Alternatively, Is it possible to :

1. Save the .blend file for each update and re-initiate the blender VR
   within blender game engine.
2. Or write the VR porcessor file as such that replaces the .blend file as
   soon as a change is observed (ex. modification time), then If the blender
   engine overwrite the .blend after each update , the VR reinitiate based on
   the new .blend.

Thank you,
