Hi,

We've got a few Mac options..

Our Arena4D desktop software runs on OSX natively. It's available as a free viewer or the paid for full feature set tool. The data format used by Arena4D can be streamed to web browsers and mobile devices via our Server software in collaboration with PoTree..

More details here

Cloudcompare is free, easy to use and provides nice visualisation of point clouds. It is available for Mac although I've never tried it personally so can't comment on how well it works.

Cloudcompare can struggle with really big point clouds, so it'd be in your interest to cut your scans down to the areas of interest and probably do some sub-sampling.

Daniel,

How many point are in a "really big point cloud"?

How much memory/cpu would you consider as adequate for a point cloud (pointcloud?) that size?

I've been working on a 27" Mac for Scene registration since I began scanning four years ago. With a fast i7 chip, plenty of RAM (32gb) it works quite well using Parallels VM to run Win7 -except for Trimble RealWorks and ReCap, that require OpenGL 3.3+. Parallels only supports OpenGL 2.2.

I later installed Bootcamp to maximize all of the RAM on the Mac and OpenGL 3.3+ on the Mac system. Both work smoothly, giving me flexibility for whatever I need to do. The latest 27" iMacs come with 5K monitors...very nice!
Good luck!

Did you tried PointCloudViz? ( www.pointcloudviz.com ) It is a free viewer with some intuitive tools (annotations, measurement, image overlay, etc..) and it works in windows, linux and mac. There is also a pointcloud server and web client.

Cheers.

If they don't need to be inside any specific application, just work with point clouds, then TruView Global is surely an option.

@Steve: I'm not the one who said "really big point cloud" ( :? ) but here's what I can say: with the 64 bits version you can load several hundreds of millions of points without too much problem. Generally you can load between 50 and 100M points with 1 Gb of memory (it depends on whether the points are colored or associated to normals, etc.). Some users even reported having loaded more than a billion points with the standard version and 3 billion in command line mode (you may have to tweak the virtual memory settings of Windows). Anyway displaying more than 200M points would be veryyyy slow (even with a high end graphic card).

Since version 2.6.2 we use a LOD structure to get a more reactive display with very big clouds. It takes some time to prepare - computations are done in the background - but once ready the interactivity is much better.

Regarding the current topic, the only issue would be that the 2.6.2 version is not available on Mac yet :oops:

That was me!

I guess what I was getting at is that if you work in Scene, for example, and you create a project with say 20 scans, and you then export that data as a .pts file or something similar, you can end up with 100's of millions of points (depending on your scan resolution of course). Expecting clients to view this on a mac (or anything for that matter) without specialized software is unrealistic. Cloudcompare will help the OP in getting the data to his client, but it won't solve the problem of viewing "really big point clouds" - as in more that about 100M points.

By specialized software I mean Recap, Scene, Scene LT etc. - Suites designed specifically for handling multiple long range laser scans

That's definitely not to say that cloudcompare isn't useful, in fact I think it's miles ahead of some very expensive pieces of software out there.
