PLY

Meshes, point clouds, and line drawings

Solidly displays surface meshes with smooth or flat shading, per-face or per-vertex colours, surface normals, and textures. Line elements render as crisp wire geometry alongside surfaces.

Point clouds open directly in the viewport, displaying in full colour or as greyscale intensity scans. In the Info tab, interactive density controls adjust how many points are drawn across the scene.

Large scan meshes and point clouds

Solidly opens dense scan meshes and point clouds containing millions of points, keeping viewport navigation smooth while orbiting, panning, and zooming.

To keep large models within system limits, Solidly sets an import memory ceiling scaled to your Mac's unified memory. This ceiling can be tuned in Settings ▸ Advanced ▸ Model Importing. In the Render tab, the Statistics section reports the active frame rate, primitive count, and GPU memory usage.

3D Gaussian splatting

Solidly renders 3D Gaussian splat scenes stored in PLY format, drawing each splat with its position, orientation, scale, opacity, and colour.

Scenes containing millions of splats navigate smoothly at full frame rates, maintaining crisp detail when moving in close.

Document inspection and visualizers

Solidly's Info tab summarises core file details, including vertex counts, element totals, ASCII or binary encoding, and header comments.

In the Resources tab, Solidly details the structure of the model, including element types, properties, and bounding box dimensions.

The Render tab provides real-time diagnostic visualizers to inspect vertex colours, surface normals, wireframes, and face orientation.
