Chapter 225: ExternalTexture

Core Idea

Represents a texture created externally with the same renderer context.

This may be a texture from a protected media stream, device camera feed, or other data feeds like a depth sensor.

Key Concepts

• isExternalTexture : boolean (readonly): This flag can be used for type testing.
• sourceTexture : WebGLTexture | GPUTexture: The external source texture.
