ShowRangeImage only displays a black image

ericwang0701
Hi everyone,

I am trying to visualize a range image by following the official tutorial (range_image_visualization.cpp). But I have troubles. The range image image is shown as a black image despite range values are correct.

only black screen in range_image

I have tried on both Mac OS X and Windows 7 with no success. Any hints why the range_image_widget.showRangeImage(range_image) displays a black image? Cloud of points is displayed correctly ?

Sincerely,
Eric Wang
