Function createGraphicsDevice

Parameters

• canvas: HTMLCanvasElement

  The canvas element.

• options: {
      antialias?: boolean;
      depth?: boolean;
      deviceTypes?: string[];
      displayFormat?: string;
      glslangUrl?: string;
      powerPreference?: "default" | "high-performance" | "low-power";
      stencil?: boolean;
      twgslUrl?: string;
      xrCompatible?: boolean;
  } = {}

  Graphics device options.

  • Optionalantialias?: boolean

    Boolean that indicates whether or not to perform anti-aliasing if possible. Defaults to true.

  • Optionaldepth?: boolean

    Boolean that indicates that the drawing buffer is requested to have a depth buffer of at least 16 bits. Defaults to true.

  • OptionaldeviceTypes?: string[]

    An array of DEVICETYPE_*** constants, defining the order in which the devices are attempted to get created. Defaults to an empty array. If the specified array does not contain DEVICETYPE_WEBGL2, it is internally added to its end. Typically, you'd only specify DEVICETYPE_WEBGPU, or leave it empty.

  • OptionaldisplayFormat?: string

    The display format of the canvas. Defaults to DISPLAYFORMAT_LDR. Can be:

    • DISPLAYFORMAT_LDR
    • DISPLAYFORMAT_LDR_SRGB
    • DISPLAYFORMAT_HDR

  • OptionalglslangUrl?: string

    The URL to the glslang script. Required only if user-defined shaders or shader chunk overrides are specified in GLSL and need to be transpiled to WGSL for use with the DEVICETYPE_WEBGPU device type. This is not required if only the engine's built-in shaders are used, as those are provided directly in WGSL. Not used for DEVICETYPE_WEBGL2 device type creation.

  • OptionalpowerPreference?: "default" | "high-performance" | "low-power"

    A hint indicating what configuration of GPU would be selected. Possible values are:

    • 'default': Let the user agent decide which GPU configuration is most suitable. This is the default value.
    • 'high-performance': Prioritizes rendering performance over power consumption.
    • 'low-power': Prioritizes power saving over rendering performance.

    Defaults to 'default'.

  • Optionalstencil?: boolean

    Boolean that indicates that the drawing buffer is requested to have a stencil buffer of at least 8 bits. Defaults to true.

  • OptionaltwgslUrl?: string

    An url to twgsl script, required if glslangUrl was specified.

  • OptionalxrCompatible?: boolean

    Boolean that hints to the user agent to use a compatible graphics adapter for an immersive XR device.
