resample_tri - alters the number of points in a triangle cloud


resample_tri [-f factor|--factor factor] [-l|--linear] [-p INT|--precision INT] [-?|-h|--help]


resample_tri is used to reduce or increase the number of triangles in a cloud. Option --factor is used to specify the relative size of the new cloud (in %). A factor of 20 indicates for instance that the cloud will be approximately 5 times smaller and a factor of 400 that it will be 4 times bigger. The program takes its input from the standard input and returns the result to the standard output.


-f DOUBLE, --factor DOUBLE

to decrease size of cloud: percentage of points to preserve (0-100). to increase size of cloud: 400, 900... 100 x n^2 (any other number is rounded to the smaller value)


linear interpolation: flat surfaces remain flat. Option only used when the cloud is expanded.

-p INTEGER, --precision INTEGER

number of decimals (default: 6)
