Vi3Dim innovative software enables a variety of objects filming techniques for 3D reconstructions.
For better experience and quality the number of rules should be followed:
VI3IDM V2 HOW TO SCAN
1.Good lighting is required (alternatively – light shine on the object). The chance for successful 3D reconstruction with insufficient lighting is low.
2. The objects made from glass or similar materials are unlikely to be reconstructed


3.The objects with reflection surfaces (mirrors etc) are unlikely to be reconstructed
4.Camera’s resolution requirements: HD or Full HD. The chances for successful 3D reconstruction for cameras with lower resolution are low.

When filming, the camera movement should be as smooth as possible. Back movements, vibrations, sudden stops and changes in speed of moving should be avoided.



vibrations and back movements
stops
speed changes

5.The camera (filming) angle should be between 0 and 90 as illustrated in Figure 4.

6.Changes in camera’s focus should be avoided during the filming

7.The filming format should be as illustrated in Figures 5 and 6

Filming Techniques:
1A: The camera is fixed. The person (desired object) is located in front of the camera. Walls A and B should not contain complex texture (simple mono-color wall is be the best option). The initial head position is 90 degrees left or right (see video “Vi3Dim V2 Face 3D Avatar First Try” from 00:11:22 to 33:44:55). Once the capture button is pressed one should slowly rotate his/her head from left to right or from right-to left (depends on the initial position) as illustrated in Figure 9. The optimal time for rotation is 40-70 seconds; remember the speed should be as constant as possible.

1B: The camera is fixed. The person should be located on rotating object (office chair would be a good idea) as illustrated in Figure 10. Rear wall should not contain complex texture (simple mono-color wall is be the best option). The optimal time for 360 degrees rotation is 40-70 seconds, remember the speed should be as constant as possible. Once the full circle is completed the filming should be stopped. See video “head 360 tutorial”.

2A: See video “Vi3Dim V2 Face 3D Avatar First Try” from 00:0:8 to 0:0:26. The person (desired object) should not move. The second person is moving with the camera on a level of desired object face as illustrated in Figure 12. Walls A and B should contain as many texture as possible (for example brick walls). The initial position of the camera is from the left or from the right of the desired object’s face. Once the capture button is pressed the second person should move with the camera from left to right or from right-to left (depends on the initial position) as illustrated in Figure 12. The optimal time for filming is 40-70 seconds. Once the full circle is completed the filming should be stopped. The camera movement could be elliptical (see figure 12) or straight line (see figure 11). Remember the speed should be as constant as possible and the movement should be as smooth as possible, no vibrations or sudden stops.



3: See video “rotation table tutorial. The camera is fixed. The object is located on rotation table as illustrated in Figure 14. Rear wall should not contain complex texture (simple mono-color wall is be the best option). The filming could be started from any location. The camera’s angle (see Figure 16) should be 35-50 degrees. The optimal time for 360 degrees rotation is 40-70 seconds, remember the speed should be as constant as possible. Once the full circle is completed the filming should be stopped.



4: See video “Vi3dim V2 inside scan” from 0:0:8 to 0:0:23. The indoors filming requires good lighting. Figures 17 and Figure 18 illustrate the possible camera’s movements. Remember the speed should be as constant as possible and the movement should be as smooth as possible, no vibrations or sudden stops. Once the full circle is completed the filming should be stopped.


5: See video “Vi3dim V2 outside scan” from 00:11:22 to 33:44:55. The outdoor filming requires lighting. Figures 19, 20 and 21 illustrate the possible camera’s movements. Remember the speed should be as constant as possible and the movement should be as smooth as possible, no vibrations or sudden stops. Once the full circle is completed the filming should be stopped. No changes in camera’s focus should be done during the filming. Another possible technique is illustrated in Figure 12.

VI3IDM V2 PROGRAM HOW TO USE
Important notice :
1)Vi3dim V2 Beta support 32bit and 64bit windows systems!
2)Video file name must not contain special characters like(-,_@#%^&*@!+=~)!
3)Please see tutorial "Vi3Dim V2 How To Scan "!
4)Please download and run reconstruction on simple movie from Vi3dim web site download section before you start trying to reconstruct their own movies.If reconstruction doesn't succeed you have to check your hardware compatibility with vi3dim V2 requirements!
Also please see at download section or online shop section minimal hardware requarements!

1) Download Vi3dim V2 to your computer.
2) Create new Folder and Unpack the package to desired folder
(for example “c:\vi3dim v2”).
3) Create movie “Any name” (From any camera that support HD or Full HD resolution) or use existing Movie that filmed with HD or Full HD camera.
4) Save and Copy the movie to Vi3dim folder (“c:\vi3dim v2\Movie.xxx).


5) Go to Windows Start button->All Programs->Accessories->Command Prompt.
6) In opened dos window navigate to Vi3dim package directory (cd\ enter -> cd vi3dim v2 enter-> dir enter).

7) Write this command to start reconstruction (rec.bat Movie.xxx) and press enter.
