Comparison of fusion resolution

[NARMELLA]

Hi

Let's see what results will be achieved by increasing the resolution in fusion.

Scanning properties :
Resolution of camera : 1056 x 704
Resolution of projector : 800 x 600
Setup type : Vertical
Number of scans : 41

Hi Narmella
Write more hardware into the PC, so realistic.

Hi Tibor

You are right .

Resolution of fusion 3000

Hi

very Nice scan!

[NARMELLA]

Thank you Egon

Seems it is good to set resolution of fusion to 2000

Fusion resolution : 2000

Fusion resolution : 2000

At 2000 is your file size is around 60-70mb? What do you do to reduce you mesh density of vertices count? how much can you reduce you mesh size without too much loss of detail?

Thanks

Hi micr0,

Fusion resolution : 2000
Output file format : OBJ
Output file size : 337 MB
Number of vertices in scan file : 3,922,912
Number of triangles in scan file :7,839,611

Fusion resolution : 2000

And by using geomagic and selecting decimate command here are results :

1- the scan file has Imported in to geomagic ( David laser scanner Fusion resolution : 2000 )

2-
Decimate using percentage : 50%
Output file format : OBJ
Output file size : 200 MB
Number of vertices in scan file : 1,962,146
Number of triangles in scan file : 3,919,804

3-
Decimate using percentage : 25%
Output file format : OBJ
Output file size : 97 MB
Number of vertices in scan file : 981,665
Number of triangles in scan file : 1,959,901

4-
Decimate using percentage : 12%
Output file format : OBJ
Output file size : 48 MB
Number of vertices in scan file : 491,211
Number of triangles in scan file : 979,950

5-
Decimate using percentage : 3 %
Output file format : OBJ
Output file size : 11.5 MB
Number of vertices in scan file : 123,413
Number of triangles in scan file :244,986

Hi
4
Tibor

[micr0]

Yeah. Number 4 looks the best for the given file size. Which version of Geomagic are you using, XOR?

Thanks for posting this.

Hi,
I'm using geomagic studio 2013 .
I have not tested rapid form XOR.

Hi
Last picture shows results of decimate command in geomagic studio 2013.
All results are good , Not only number 4.
In reverse engineering , I prefer to choose number 5 .( Memory allocation will be very good to work on and it has enough data to extract details by surface modeling )
In other process like 3d printing or some others need to choose number 1 or 2 or 3 or 4 .
