Scene Runtime

These classes are exported because advanced integrations sometimes need them directly.

Main classes

• String3DScene creates and stores objects
• String3DRenderer owns frame output
• String3DSynchronizer maps DOM state to scene state
• String3DCamera manages projection and screen-to-world helpers
• String3DObject wraps a scene object plus geometry and material metadata

Use case

Most integrations do not instantiate these classes directly. They become useful when you are extending the runtime, testing a custom provider, or instrumenting advanced behavior.
