I have xyz surface data of an object which I'd like to display on the screen in a similar way as I would be able to in e.g. CloudCompare or MeshLab. My thought was to generate a bitmap using some pre-defined viewpoint. I've loaded my xyz/pcd into a 3 channel 32 bit float Mat. Does anyone know of a straightforward way to do this with opencv. I do not have viz.

2017-10-31 10:03:46 -0600	commented question	bitmap representation of a point cloud. Thank you @berak. Not quite what I had in mind but maybe useful nonetheless. I guess what I want is closer to PCL land.

2016-10-05 09:21:36 -0600	commented answer	Multiple opencv 3 & IPP build issues Any new developments here? I'm having very similar issues. I got past the issue with the built-in IPP by moving to a fresh VM with no previous IPP installation. However, I'm also interested in using my own IPP since it may (or may not - can't find any information) improve performance even further. I'm running into linker errors which look like the same as Dan's but since the whole process is a part of a debian packaging script I'm not sure if I can use his solution.

2014-11-25 05:34:51 -0600	asked a question	Optimization level for gcc linux 32 Found this announcement SPECIAL NOTE for Ubuntu x86 12.04 users: By default OpenCV is now built with "-O2" optimization flag >instead of "-O3" on 32-bit Linux. The compiler in the 32-bit version of Ubuntu 12.04 produces incorrect >code with "-O3", so it's strongly recommended not to use this flag. You are welcome to try out the latest and greatest OpenCV! Best regards, OpenCV development team. I notice that -O2 is still used as default in the CMake files for v3.0 beta Is the issue with using -O3 not resolved for newer versions of gcc than what is supported by Ubuntu 12.04? Is there a significant performance penalty associated with having to use -O2 ?
