Unity

Pointcaster integration for the Unity game engine ships as a package you can include directly from Unity's package manager. This package supports Unity 2021.3 onwards and is compatible with both URP and the built-in render pipeline. Native libraries are included for Windows x64 and Android (armeabi-v7a and arm64-v8a).

Open the Package Manager window inside Unity and add a new package from the following git URL:

Pointreceiver Mesh Host

The quickest way to get a point cloud into a scene is to drag the Pointreceiver Mesh Host prefab from the package into your scene. It connects to Pointcaster and creates a child object with a mesh for each point cloud channel it receives. Points are drawn as camera-facing quads.

• Point Caster Address / Point Cloud Port: the Pointcaster instance to connect to. The port defaults to 9992.
• Subscription: receive all channels, or only the channel matching Address.
• Point Size: the width of each point, in world units or screen pixels depending on Size Mode.
• Point Scale Multiplier: scales per-point sizes sent by Pointcaster (e.g. from a PLY file's attributes). Only applies in world units.
• Shape: draw points as squares (cheapest) or disks.
• Tint: a colour multiplied with each point's colour.

To change hosts at runtime, call SetAddress(address, port), or call Reconnect() after changing the address fields directly.

VFX Graph

For use with the Visual Effect Graph, add a Pointreceiver Host to the scene, then add a PointCloudBinder to your Visual Effect (under VFX/Property Binders). Set its Channel Address to the channel to draw. The binder exposes the cloud to the graph as Positions and Colors textures and a PointCount integer.
