3.8 Using ptc2brick

ptc2brick converts one or more point cloud files into a single brick map.

The general command line syntax is:

ptc2brick [options] <in.ptc> [more input files] <out.bkm>

The available options are:

` -maxdepth d'

Specifies a maximum depth `d' for the brick map tree. Smaller depths will give smaller files. The default maximum depth is 15.

` -maxerror e'

Specifies maximum tolerated error `e' in the brick map. This is a trade-off between accuracy and file size.

` -radiusscale s'

Specifies a scale `s' that will be applied to all points' radii. For `s' higher than 1, blurrier and smaller brick maps are created. Specifying a value smaller than 1 is not recommended and will create large and inefficient brick maps.

` -newer'

Only builds the brick map if one of the input files is newer than the output. This option has no effect if the output file doesn't exist.

` -h'

Prints a help screen.

A brick map is a 3D texture file format that is suitable for anti-aliased lookups. Please refer to Baking, bake3d shadeop and texture3d shadeop for further discussions.
