When you turn on your HoloLens and start the ”Space Catcher” App, simply place the home screen somewhere convenient in the room. The space ball will be the focal point of the screen, and as you move around the room, the main menu will rotate to face you.
The home screen has four menus: the quality of the scan (“triangles count select”), the start/stop function (“start stop scan”), the placement of the scan (“clone mesh”) and save(“save model”).
The “clone mesh” and “save model” menus are not active if a scan has not been made.BackNext step
Quality of scan
Choosing the right number of triangles depends on your needs – fewer triangles makes for a faster scan which uses less data and uploads quicker, while more triangles provide a higher-resolution and thus data-rich scan with longer upload time. Set your gaze on your chosen number and select via hand motion or using the word “select.”BackNext step
To start the scan, set your gaze on “start scan” and select via hand motion or using the word “select.”
After starting the scan, begin looking at the walls and surfaces around you. You will see the mesh start to appear. Especially for higher-resolution scans, keeping your gaze in one place or area will resolve more triangles in that spot until saturation. A fast-moving gaze will be lower resolution; however, an area can be covered multiple times to increase the clarity. Stop the scan when you are finished.BackNext step
Save mesh to OneDrive as OBJ
Before integrating the room with any external objects, it is necessary to save the room to OneDrive.
To do that, set your gaze on the save menu and select “from slot 1.” This selects the item in slot 1 and prepares it for upload to OneDrive. The OneDrive save screen will pop up above your home screen, and you can choose the location for it to be saved. *Note: A wireless connection is necessary to save to OneDriveBackNext step
Stop scan and show mesh
Stopping the scan enables the “clone mesh” menu. Selecting “slot 1” will shrink the mesh into a small model next to your home screen, at the same height as the space ball. If you want to move the room to eye level, move the space ball up. If you want to be able to look down into the room, move the space ball down.
The creation of the “clone mesh” permits the user to be able to look into the room and see how it looks from multiple angles, including its relative scale and the size of different elements within the room.BackNext step
Following upload, you can go back to the home screen and start scanning again – perhaps to scan a new room or new elements in the already-scanned rooms. This time, you will save to “to slot 2” and you will see that a second model appears next to the first one, in a different color, if you choose another slot. As before, you can save to OneDrive by selecting “from slot 2.” Saving to “slot 3” works in the same manner.BackNext step
How do I get the best scan results?
Move closer to the object but no closer than 80cm/2.5 feet away.. The sensors need a spacial spatial stereo perspective to an object. If you are too close closer, the perspective doesn’t allow the object to be seen in the proper way.
Which objects cause problems in scanning?
All highly reflective materials are a challenge for HoloLens sensors to scan. HoloLens works by taking a picture and is a snap of the time the light needs to go to an object an back. Therefore, a mirror is almost impossible to scan without errors. Similar problems will occur while scanning:
- High gloss surfaces (metals, mirror, leather)
- Wet surfaces
What does the number of triangles per square (TPSM) meter mean?
At the moment, this is not the exact number of triangles but the maximum number of triangles which can be used to represent the surface. At the moment, Microsoft HoloLens supports only three levels. The maximum level is 2000 TPSM.
If I’m scanning big area or another room, I don’t see the “space ball” anymore. How I can stop the scan or clone the mesh?
You can use the voice command: “come to me” to transfer the space ball to a place in front of you. Place the ball again with your head using the command “select”.
When I performed the ‘clone mesh’ action after the scan, one of the meshes appears to be inside the wall. What should I do?
If you select the space ball by gazing it and selecting it (by gesture or voice command), you can change the position of the ball and the scanned meshes that are connected to it.
If I try to save, a pop-up appears that says I need the OneDrive app. Why?
The app is using the integrated connection to OneDrive to save the object to the cloud. In order to make it work, you will need to install the OneDrive app. Because HoloLens needs a Microsoft Account to be configured, this account will be automatically used as your OneDrive.
We are not able to save to a root folder. Please select a subfolder in order to save the mesh to the OneDrive. You can choose any name for the filename.
How I scan a single object, like a person or another object?
Please clean the mesh before scanning the single object. Go to “Settings” -> Spaces and delete your current space. We are working on a direct way to remove the mesh.
