George Shramko and colleagues propose a representation that extends the points of 3DGS to curves (polylines). Points are included as zero-length curves, and the authors position the method as a superset of 3DGS.
Why it mattersIn practice in Japan, possible uses include handling character hair and vegetation in games and VFX, and capturing real-world cables and similar objects for robot simulation. However, the available material does not show whether an implementation has been released or how long processing takes, so practicality awaits further verification.

Yuxi Hu and colleagues have presented BudgetSplat, a general-purpose 3DGS method that lets users set a retention ratio to control the number of output Gaussians. The authors say a single model handles different numbers of input views and different budgets.
Why it mattersWhen 3DGS is used on the web or on mobile devices, data size and rendering load are constraints. If the size can be specified at generation time, it could be used to serve different outputs depending on the capability of the target device.

3D Gaussian SplattingのPLYファイルをファイル一覧のサムネイルで確認できるOSS「SplatThumb」が、v0.5.0からmacOS 13以降に対応しました。MITライセンスで、Windows版と同じ視点保存ファイルを共有できます。
Why it matters3DGSの学習結果は同じ`.ply`拡張子のファイルが大量に並ぶことが多く、名前だけでは中身を判別しにくい場面があります。サムネイルで内容を確認できれば、制作・検証時のデータ整理が楽になります。\n\nMacとWindowsの両方で作業するチームでは、視点ファイルを共有できる点が実務で役立つ可能性があります。ただし、MacではFinderのプレビューペインやQuick Lookは引き続きAppleの標準表示のままです。
