renderer

state

update

• update(state?: WebGLGlobalParameters, force?: boolean, vaoLast?: boolean): void

  Sets the global WebGL state. Parameters are updated on the WebGLRenderingContext only if they are defined in the input state, and different from the current state.

  When force is true, and state is defined, parameters on state are always set, regardless of the current state.

  When force is true, and state is undefined, the current state is used to reset all the parameters.

  Parameters

  • Optionalstate: WebGLGlobalParameters

    The state to set. If undefined, the current state is used when force is true.
  • Optionalforce: boolean

    If true, the state will be set regardless of the current state. Default false.
  • OptionalvaoLast: boolean

    If true, the VAO will be set last. Otherwise, it will be set first. This is useful when performing state changes that will affect a VAO, such as bindings.elementArrayBuffer. Default false.

  Returns void
