Spherical Harmonics added to three.js library, GaussianSplats3D

Mark Kellogg, developer of the 3D Gaussian Splatting three.js library, GaussianSplats3D has released an update to Version .4.0. Previously Kellogg had added Web XR support to the library.

The big excitement for this release is the added support for 1st and 2nd degree spherical harmonics into the viewer. Previously spherical harmonics, which give Gaussian Splatting their view dependent effects were not supported. This means going forwards, all captures displayed through GaussianSplats3D that use the toggle will be more lifelike.

In order to display them, you must set the sphericalHarmonicsDegree to the requested degree of 1 or 2. Currently the default value is 0, but Kellogg has made it really easy to toggle on and off the settings through the website.

Additionally, the ksplat file type which Kellogg created, now is also able to export Spherical Harmonics. As a reminder, .ksplats are compressed versions of .plys.
