I’m trying to use Jawset PostShot to export a .ply
point cloud for use with the SOGS (Self-Organizing Gaussians) compression tools and the 3D Gaussian Splatting (3DGS) pipeline. Following a similar pipeline as presented here :
However, SOGS/3DGS requires extra attributes in the .ply
file (such as normals nx, ny, nz
, opacity, scale, rotation, and SH coefficients like f_dc_0
, etc.), but my PostShot .ply
export only contains position and color.
Is this normal for PostShot exports? Are those additional attributes just stored under other names, or are they simply not supported by PostShot at export time?
Is there a way to export these extra fields directly from PostShot, or a recommended workflow to generate a fully 3DGS-compatible .ply
?
If not, are there any tools or scripts that can help convert or add the missing fields for use with SOGS compression?
Thanks for any advice or tips from anyone who’s managed to go through this process!
