Best 3D method

I have been successful doing geomaps with MME. I'd like to test the 3D feature. How should I plan my flight, a little confused about taking angled below roof lines shots. Must all shots be at the same height?

Getting the horizontal shots needed to make a full 3D model of a structure come out properly requires some manual flying.

Image uploaded to Maps Made Easy do not have to all be from the same elevation but it helps keep the overlap organized.

When taking oblique images of the sides of structures it is important to include 45 degree shots of the sides as well  and get plenty of overlap between them all.

As always, don't include shots that have any sky above the horizon in them.

Do I upload normally as a geo map or do I check the 3D options?

If you are going to go through the effort to take oblique images make sure you select the "Full 3D" processing checkbox in the Point Use tab if you want overhung areas to be rendered. Regardless, the detailed texturing of the vertical areas will use those images.

That's a nice looking picture! You should probably change your default zoom level to 21 since you have it set to show the elevation layer by default. The max elevation zoom level is the max zoom level of the photo layer minus 2.

Thanks Ryan. I flew 3 missions; two MME app at 90 degrees to each other's path and a POI manual with plenty of overlap. All 3 at 150 feet.

The creation of the 3D models and viewing them is two pretty different topics. The models created by Maps Made Easy are usually pretty big. 

We create a simplified (10,000) face version of the model that is easy to handle and usually loads pretty quickly in a web interface. This file is around 1 MB. 

The OBJ file sets that are created can range from 10s of MB to 10s of GB. That is far too big to be useful in any sort of web interface since it would take forever to load. 

We usually recommend using MeshLab for viewing the full detail 3D files since it is better handled on a real computer after being downloaded. 

The hybrid option here is to use a service like SketchFab which will take our OBJ files (or a decimated version of it made with MeshLab) and put them in an easy to share web widget than is optimized for showing higher resolution 3D models on the web. More detail, less bandwidth.

Nice pic indeed Luis.  thanks Zane for the answer.  Im going to try one of my 3D maps on Meshlab (couldn't get it to work last time) and see what it looks like as opposed to the low res version that I was able to view by putting it on my website http://www.kestrelvideo.com/3d-mapping-and-surveys

So is it the case that there is no way of sending a detailed 3D model to clients.  they either have to embed the low res one on thier website and view it that way or go through the whole Meshlab procedure?
