We seem to have yielded our most interesting and detailed textured meshes from images of spaces with high contrast lighting.

We began by feeding images into Grasshopper, a visual scripting plug-in for Rhino, and generating printable 3D models.

Photogrammetry opened up the possibility to generate models from a variety of sources, from things directly in front of you to videos found online.

There are a number of exciting practical and creative applications for photogrammetry.

While we played around with a variety of proprietary and open source programs, it seemed important to develop an accessible workflow of all open or shared source software for anyone to explore the multitude of possibilities.

While the software we used was amazing in many ways, they definitely have their flaws and limitations when compared to their proprietary competitors.

You can upload a series of jpg.,ppm.

VisualSFM to create a dense point cloud that can be turned into a textured mesh using Meshlab.

Just know that the types of images, and the variety amongst the images you select have a big influence on the resulting point cloud.

I would recommend using images that were taken at relatively similar distances from your subject, close-ups or zoomed out images have a tendency to dilute the quality of the point cloud.

Their are installation guides for Windows, Linux, and Mac on the VisualSFM website which is listed above.

To install for Windows, all we had to do was download VisualSFM from the installation guide ( ), then install Yasutaka Furukawas CMVS software (for dense reconstruction), we used Pierre Moulons binaries, You must put the CMVSPMVS binaries into your VisualSFM folder that was created when you downloaded the program, otherwise it will not work properly.

The only issue we werent able to resolve, was that we never got our command line running, although a friend downloaded VisualSFM for Linux, and had no issue with the command line.

Next you will create the sparse reconstruction, using the compute 3D construction icon.

Then you can create the dense point cloud using the CMVS icon, this step will take the longest to compute.

You can switch your view between the sparse reconstruction and the dense point cloud by using your tab key.

Here you will see all the camera positions that have been detected.

Once this step is finished you are ready to bring your dense point cloud into Meshlab to create your textured mesh.

We will be using Meshlab to transform our point clouds into meshes as well as to quickly generate the UV textures for our meshes from the collection of photos used to make the point clouds.

Meshlab is pretty intuitive, and the texture mapping works great.

However, we were having some problems with Meshlab crashing at various points in the process even with our smaller point clouds, so its a good idea to frequently export your current version of the file, especially since there is no undo option in Meshlab.

The second issue we had was trying to generate the poisson mesh using a point cloud file we had already edited.

You can download Meshlab here for Mac OS X, Linux, and Windows.

Mr. P Meshlab Tutorials is a great resource for learning how to use Meshlab.

In here you should find the bundle.rd.out file.
