Pcx - Point Cloud Importer/Renderer for Unity


Pcx is a custom importer and renderer that allows for handling point cloud data in Unity.

System Requirements

  • Unity 2019.4

Supported Formats

Currently Pcx only supports PLY binary little-endian format.

How To Install

The Pcx package uses the scoped registry feature to import dependent packages. Please add the following sections to the package manifest file (Packages/manifest.json).

To the scopedRegistries section:

  "name": "Keijiro",
  "url": "",
  "scopes": [ "jp.keijiro" ]

To the dependencies section:

"jp.keijiro.pcx": "1.0.1"

After changes, the manifest file should look like below:

  "scopedRegistries": [
      "name": "Keijiro",
      "url": "",
      "scopes": [ "jp.keijiro" ]
  "dependencies": {
    "jp.keijiro.pcx": "1.0.1",

Container Types


There are three types of container for point clouds.


Points are to be contained in a Mesh object. They can be rendered with the standard MeshRenderer component. It's recommended to use the custom shaders included in Pcx (Point Cloud/Point and Point Cloud/Disk).


Points are to be contained in a PointCloudData object, which uses ComputeBuffer to store point data. It can be rendered with using the PointCloudRenderer component.


Points are baked into Texture2D objects that can be used as attribute maps in Visual Effect Graph.

Rendering Methods

There are two types of rendering methods in Pcx.

Point (point primitives)

Points are rendered as point primitives when using the Point Cloud/Point shader.

Points Points

The size of points can be adjusted by changing the material properties.


These size properties are only supported on some platforms; It may work with OpenGLCore and Metal, but never work with D3D11/12.

This method is also used when the point size is set to zero in PointCloudRenderer.

Disk (geometry shader)

Points are rendered as small disks when using the Point Cloud/Disk shader or PointCloudRenderer.


This method requires geometry shader support.
