Chapter 248: CubeRenderTarget

Core Idea

This class represents a cube render target. It is a special version of WebGLCubeRenderTarget which is compatible with WebGPURenderer.

Key Concepts

• isCubeRenderTarget : boolean (readonly): This flag can be used for type testing.
• texture : DataArrayTexture: Overwritten with a different texture type.

Reference Tables

Constructor

Signature
new CubeRenderTarget( size : number, options : RenderTarget~Options )

Properties

Property	Description
.isCubeRenderTarget : boolean (readonly)	This flag can be used for type testing.
.texture : DataArrayTexture	Overwritten with a different texture type.

Methods

Method	Description
.clear( renderer : Renderer, color : boolean, depth : boolean, stencil : boolean )	Clears this cube render target.
.fromEquirectangularTexture( renderer : Renderer, texture : Texture ) : CubeRenderTarget	Converts the given equirectangular texture to a cube map.

Key Takeaways

1. CubeRenderTarget extends: EventDispatcher → RenderTarget
2. Most relevant properties: isCubeRenderTarget, texture.
3. Key methods: clear, fromEquirectangularTexture.
