If you check the “Auto. grab texture” option, DAVID will record a texture with each scan. If the texture is
too bright or too dark, you can adjust the texture settings in the Texturing menu (see below).
•
With your mouse, you can rotate, move and zoom the 3D view.
•
The scans need to overlap sufficiently so that they can be combined/aligned later on. Generally, 6-8
scans of different views around an object are required, plus possibly a few of the top and bottom sides.
Grabbing a texture with each scan can help with the automatic or manual alignment.
•
Save each successful scan as an OBJ file (“Save As“) and/or add it to the List of Scans.
After each click on “Add to list”, you can immediately align the new scan to the previous ones
(Shapefusion menu, see next chapter). Alternatively, you can first collect more scans in the Structured
Light menu, and align them all later.
Menu
“Texturing”
You can record a texture with each scan. It is coloured if you are using a colour camera, otherwise it is
greyscale.
The texture usually requires different illumination settings. When the Texturing menu is open, you can adjust
Projector Brightness, camera Exposure or other camera properties as you like, without influencing the scan
settings. A decent texture is like a good photo: uniform illumination, not too bright, not too dark. It may be
helpful not to use the projector as a light source (set Projector Brightness to 0), but instead use diffuse
environment light in the room.
•
The button “Grab Texture” records a new textures and applies it to the scan at hand.
•
All settings here are stored separately. For the following scans, you will not have to open the Texturing
menu each time. Instead you can use the “Auto. grab texture” option in the Structured Light menu.
