Class UniformBufferFormat

constructor

• new UniformBufferFormat(
      graphicsDevice: GraphicsDevice,
      uniforms: UniformFormat[],
      options?: { pack?: boolean },
  ): UniformBufferFormat

  Create a new UniformBufferFormat instance.

  Parameters

  • graphicsDevice: GraphicsDevice

    The graphics device.

  • uniforms: UniformFormat[]

    An array of uniforms to be stored in the buffer.

  • Optionaloptions: { pack?: boolean } = {}

    Options.

    • Optionalpack?: boolean

      Reorder the uniforms to minimize the padding of the std140 layout: uniforms occupying whole 16-byte rows first (vec4, matrices and arrays), then each vec3 followed by a scalar, then vec2s and the remaining scalars. The uniforms of the format are then in layout order rather than in the order of the array. Only use it when the shader declaration of the buffer is generated from this format, and never against a hand-written declaration, whose member order has to match the array. Defaults to false.

  Returns UniformBufferFormat

uniforms

get

• get(name: string): UniformFormat | undefined

  Returns format of a uniform with specified name. Returns undefined if the uniform is not found.

  Parameters

  • name: string

    The name of the uniform.

  Returns UniformFormat | undefined

  • The format of the uniform.
