1.Vi3Dim software

To create 3d object from a simple web-cam you need: 1.Vi3Dim software. 2.Web-camera. 3.Check-Board printed on A4 page. 4.Light. 5.Source object. Algorithm: 1)Place the check-board on the flat empty space (table) check that there is enough free space to rotate the check-board 360°. 2) Check that there is enough light in the room, if not then use some additional lighting. 3)Open Vi3Dim software.

7.Rotater(hand).

To create 3d object from a simple web-cam with Vi3Dim software you need:

Algorithm: 5)Put your hand on the edge of the check- board (try to not cover many of the black squares with the hand). 6) Press start capture button and begin to rotate the check-board slightly such way that the desired object will spin around his center and will move by axis X/Y as less as possible. If everything is ok you will see the yellow squares (indicators) on the black squares edges intersection and they moving with the check-board on the Vi3dim software screen.

Desired object spin center

If the yellow squares indicators loses there right spot that mean: 1.You spin the check-board to fast 2.The camera is not in the right spot 3.You already have all views from this angle.

Solutions: 1. Try to spin the check-board slowly. 2. Try to find other spot for the camera. 3. Continue rotate the check-board. *maybe more/less light required.

Make new cube data:

To create new cube data with other (Vertex set cube size) parameter left click mouse button on yellow circle and drag mouse (left/right) to change the value . Then click on with left mouse on the (Make new cube data). Maximum cube size for A4 page is 8 For a better results choose cube size that equal or little bit bigger then desired object. To check the desired object size just put object on the check-board and count how many squares it cover.
