What is the Matterpak?

The MatterPak Bundle is a set of 3D scan assets of interest to architects, civil engineers, property management and insurance companies. The Matterpak can be purchased in addition to the 3D Tour Scan. The data can be imported into various third-party programs.

The MatterPak contains the following four 3D-Scan-Assets:

  1. Colored 3D Point clouds (Pre-registered pointcloud im .XYZ Format)
  2. 3D MESH file (.OBJ) including the required texture map image files (.JPG)
  3. High definition reflected ceiling plan image to create a ceiling plan (as .JPG) in multiple files for multiple floors
  4. high res floor plan image. It is similar to the ceiling plan picture but flat from the floor.

Let's take a closer look at these 4 files first and then see what we can do with them.

1. The colored 3D point cloud in .xyz format

Most users only know point clouds in e57 or reCap format. However, XYZ is an open standard that can be imported into numerous programs.  

The quality of the point cloud depends on the quality of the recordings and the density of the scans made with the Matterport Pro2 camera. If you (additionally) work with the Leica BLK360, you get even better point clouds with deviations in the range of only 0.1 percent. This data is available just a few hours after recording and uploading.   

Matterport Pointcloud

If your CAD software supports point clouds directly, in most cases you can also import Matterport xyz point clouds directly. This works e.g. with most Autodesk products. After importing the xyz. point cloud into the ReCap software and you can attach the ReCap project to Autocad, Revit, Inventor, Navisworks etc. and continue working there.

2. The 3D file in .obj format

Analogous to XYZ point clouds the Matterpak offers a ready-to-use 3DOBJ files. The 3D OBJ file is a 3D model generated by the Matterport Cloud. Our customers use this for visualizations or as a basis for rough building geometries for planning in CAD applications. This OBJ file then looks something like this. 

Matterport MatterPak OBJ Datei

For most users, an OBJ file is not necessary. But some 3D developers and VR enthusiasts can use this OBJ file to instantly start their projects with a 3D model of a real place. But you have to know that the textures and polygonal composition of this OBJ file is problematic for most 3D applications.

The figure below shows you how this OBJ file is structured:

The OBJ files have a scale of 1 unit = 1 meter. You may need to update the scale in your 3D software or rescale the model after loading.

3. and 4. The ceiling plan image and the floor views - in *.jpg format

Here is the ceiling plan:

And here is the floor view:

Matterpak Fussboden-Ansicht

Both files are of interest to architecture, engineering, and construction (AEC) clients.

The high-resolution floor plans and also the ceiling mirror provide a quick vertical view of everything on the floor and ceiling. See all ventilation shafts, wiring, plumbing, insulation and more at a glance with the ceiling mirror image.

What is that good for? What can we and what can you do with it?
