Couldn't create OpenCL image (-40)

RecFusion

Hi, I’m trying to run the ConsoleReconstruction example with a custom sensor that i’m integrating the SDK with.

When it comes to the part that the reconstruction is instanciated, i get the following error:

Has anyone had the same problem? Thanks

I fixed the problem. The point was that my sensor was returning the image dimensions of 0 x 0.

This is an important issue in RecFusion 2.2.0. If sensor is closed, then its getters like colorWidth() or depthWidth() return 0 (also methods returning intrinsics matrices). These functions work correctly only after opening the sensor with open(), which is not the case in RecFusion 1.3.6, which, if I am not mistaken, returns the correct color/depth image sizes at all time.

I think it is something worth mentioning in the documentation.
