BillboardClouds Runtime Package

Back to package index

BillboardClouds provides utilities for converting detailed geometry into billboard cloud representations. It is useful for level-of-detail and vegetation-style rendering workflows.

Build Status

  • Registered from EvoEngine_Packages/CMakeLists.txt by default.
  • Builds as the shared library target BillboardCloudsPackage.
  • Registers BillboardCloudsConverter through PackageRegistrar.

Main Responsibilities

  • Collect triangles from target meshes.
  • Cluster triangles into billboard planes.
  • Project and rasterize geometry into billboard textures.
  • Transfer material channels such as albedo, normal, roughness, metallic, and AO.
  • Dilate generated textures to fill invalid pixels.

Main Entry Points

Source Role
BillboardCloud Core data structures and algorithms for clustering, projection, rasterization, and dilation.
BillboardCloudsConverter Private component exposing conversion through the editor.

SDK Integration

The package works with SDK Mesh, Material, private components, editor inspection, and generated geometry/texture outputs. It can be loaded from the app runtime Packages folder.

Future Work Notes

Keep billboard generation logic in this package. If a feature becomes a general mesh simplification, material transfer, or texture baking primitive, consider whether it belongs in the SDK or TextureBaking instead.
