PlayCanvas Adds a Three Point Grid Alignment Tool to SuperSplat 2.32
Michael Rubloff
PlayCanvas has released SuperSplat 2.32, which adds an Orient tool that aligns a splat to the grid from three picked points. Straightening a Z-up import or a tilted capture in the browser based gaussian splatting editor previously meant setting the rotation by hand on the transform gizmo.
The tool reads its target from a Grid Plane setting added in the same release, which sits under Show Grid and renders the infinite grid on XZ, XY, or YZ in perspective mode. The orthographic axis views, which arrived in SuperSplat 1.8, keep their automatic plane selection, and the setting persists in the document view settings.
Point placement runs entirely on the CPU, using the same full scan approach as point select. A clicked point lands on the click ray at the median visible depth of the gaussians whose centers project near the cursor, composited front to back by opacity and remaining transmittance. Opaque surfaces win over denser geometry behind them, and near transparent floaters defer to the surface below.
Align to Grid rotates and translates the splat along the shortest arc about the centroid of the three points, so the clicked region stays put laterally and settles onto the grid with heading preserved. The plane normal snaps to a splat local axis within 3 degrees, so a Z-up import produces an exact quarter turn instead of 89.7 degrees. The move applies to the whole entity as one undoable operation, and the side of the plane facing the camera becomes up.
A follow up extended the Orient tool with persistent, undoable local frames derived from the picked points and world space edge lengths under Show Dimensions.
SuperSplat 2.30 had added LCC2 import with a format agnostic level of detail dialog. SuperSplat 2.32.1 added a capability aware video export preflight that probes each visible resolution against VideoEncoder.isConfigSupported. SuperSplat 2.32.2 adds 8K render presets, 7680x4320 for standard video and 7680x3840 and 8192x4096 for equirectangular output, and disables any preset above the device maxTextureSize.
