What problem does it solve?

Provides concise, targeted guidance for understanding, configuring, and troubleshooting Orkid's scene graph rendering system so developers can assemble 3D scenes, cameras, lights, and drawables without digging through scattered source files.

Core Features & Use Cases

• Scene composition: Explains Scene/Layer/Node hierarchy and how to create and manage layers and drawable/light/probe nodes.
• Drawable and instancing guidance: Describes ModelDrawableData, InstancedModelDrawableData, CallbackDrawable and text/billboard drawables and how to add them to layers.
• Camera & viewport setup: Shows CameraData, CameraDataLut, EzUiCam usage, event handling, and embedding SceneGraphViewport for interactive rendering.
• Lighting and probes: Covers point/directional/spot/ambient light types, shadowing flags, light properties, and probe usage.
• Thread-safety and runtime: Notes LockedResource access patterns, scene.updateScene and scene.renderOnContext integration points, and Python binding references.

Quick Start

Ask how to set up an Orkid Scene with a main CameraData and EzUiCam, add a ModelDrawable node and a directional light, and render it using scene.updateScene and scene.renderOnContext.
