The Matterport E57 file contains a high-density point cloud for all scan locations in the Matterport space. It contains point cloud, pano images, and metadata from each scan location. The file format, .E57, is a compact, vendor-neutral point cloud format that’s defined by the ASTM E2807 standard. This format is widely adopted by most 3D design applications, so you can use your Matterport digital twin in a wide range of applications, including but not limited to:
- Autodesk Recap Pro
- Leica Register 360
- Leica Cyclone
- Faro Scene
- Autodesk Revit
- Autodesk Navisworks
- Trimble Sketchup
- Trimble Business Center
- TopCon Magnet
For a comprehensive list of supported applications, refer to this website.
With the E57 file:
- Architects and designers can conceptualize designs with a detailed understanding of the space.
- Project stakeholders and construction teams can collaborate more efficiently.
- Building operators can maintain inventories of equipment and assets across a portfolio.
The E57 file is for architects, MEP engineers, general contractors, mechanical engineers, electrical engineers, BIM managers, VDC managers, and other construction professionals who need a higher density point cloud than the Matterpak .XYZ point cloud file provides to complete complex workflows.
What Is a Point Cloud?
A point cloud is a 3D description of spatial data consisting of geometric points in space, as measured by capture devices. These points typically represent the 3D shape of a physical object. Each point position has its set of Cartesian coordinates (X, Y, Z). Point clouds are most commonly used to capture the existing (as-built) conditions of a structure. Point cloud data is commonly used to extract analysis from these structures, and to import into 3D design and BIM software workflows.
How is E57 different from a Matterpak?
E57 is a single file containing a colorized point cloud, as opposed to the Matterpak bundle which has several components (colorized point cloud, reflected ceiling plan, high-resolution floor plan, and 2D mesh file). The Matterpak is designed to provide decimated point cloud information from the capture device to create a light-weight solution that can be accessible from anywhere, including a phone or tablet.
E57 is a higher-density point cloud that processes a much larger dataset coming from the capture device which results in more than 10x the detail derived from a Matterpak. Compare the following examples:
