Draco is a format for efficient compression of 3D graphics data such as geometric meshes or point clouds.
draco_encoder is the compression tool.
The following options are available:
-iinput
input file name in .ply or .obj format
-ooutput
output file name
-qpvalue
quantization bits for the position (default: 11)
-qtvalue
quantization bits for the texture coordinates (default: 10)
-qnvalue
quantization bits for the normal vector (default: 8)
-qgvalue
quantization bits for any generic attribute (default: 8)
-clvalue
compression level from 0 to 10 (default: 7)
--skipattribute
skip a given attribute (NORMAL, TEX_COORD, GENERIC)
--metadata
use metadata to encode extra information in mesh files
-point_cloud
force the input to be encoded as a point cloud
Negative quantization values will skip the specified attribute
