Ok so we have the points, lets make a mesh - a polygon model of the building. In MeshLab clean up some of the stray points. You can do that by selecting points and deleting them. The selection icon is the one with three dots and the cursor arrow. Click that and drag out a box over some points and they turn red to show they are selected. The delete is on the far right which is the three dots and a triangle with a big X through it.

Once you have the vertices for the building without ...

So you have run the app and got the model out and extracted the text file of points which should look like this...

So this Insight3D is a gem of an app. You can find it here:

As stated on the page "it hopes to be "Photosynth + Canoma". Or "boujou + Imagemodeler". But it's also free and opensource (GNU AGPL 3)" - ok thats me sold then... Its not quite up to the mentioned apps but its heading in the right direction and seemed very stable to me. At this point its not super user interface easy but once you have run it through ...

I thought I would start a blog about some tech stuff that I have mentioned in the past on various posts but I thought it would be better if I brought it all together. I don't expect that this will be relevant to many people but I am forever surprised by the few who do post in some amazing related links to the bizarre stuff that I post sometimes and these make it all the more worthwhile.
