scale

Protected _translation

_translation: vec3

Protected _vertexArray

_vertexArray: VertexArray

Vertex array used for binding the rectangle's buffer(s).

Protected _vertexLocation

_vertexLocation: GLuint = 0

Static Protected INDICES

INDICES: Uint8Array = new Uint8Array([0, 1, 2, 3])

Static Protected VERTICES

VERTICES: Float32Array = new Float32Array([-1.0, 0.0, -1.0,-1.0, 0.0, +1.0,+1.0, 0.0, -1.0,+1.0, 0.0, +1.0,])

Accessors

buffers

  • get buffers(): Array<Buffer>

context

initialized

  • get initialized(): boolean

rotation

  • set rotation(q: quat): void

scale

  • set scale(s: vec2): void

transformation

  • get transformation(): mat4
  • Get the transformation matrix to transform the unit plane to the specified translation, scale and rotation.

    Returns mat4

translation

  • set translation(t: vec3): void

vertexArray

Methods

Protected assertInitialized

  • assertInitialized(): void
  • Asserts the objects initialization status to be true. Note that the implementation is cached and forwarded to either an empty function when initialized and to an acutal assert(false) otherwise.

    Returns void

Protected assertUninitialized

  • assertUninitialized(): undefined
  • Asserts the objects initialization status to be false. Note that the implementation is cached and forwarded to either an empty function when uninitialized and to an acutal assert(false) otherwise.

    Returns undefined

bind

  • bind(): void

Protected bindBuffers

  • bindBuffers(): void

draw

  • draw(): void

initialize

  • initialize(aVertex?: GLuint): boolean
  • Creates the vertex buffer object (VBO) and creates and initializes the buffer's data store.

    Parameters

    • Default value aVertex: GLuint = 0

      Attribute binding point for vertices.

    Returns boolean

unbind

  • unbind(): void

Protected unbindBuffers

  • unbindBuffers(indices: Array<GLuint>): void

uninitialize

  • uninitialize(): void

Static Protected assertInitializedFalse

Static Protected assertUninitializedFalse

Static assert_initialized

Static assert_uninitialized

Static initialize

  • Method decorator for initialization of Initializable inheritors. This decorator asserts the initialization status of the instance that is to be initialized, invokes its initialization with arbitrary number of parameters, and sets the initialization status to the initialization success (either false or true). In order to encourage the use of assertInitialized and assertUninitialized they are dynamically bound to either a static, always-failing assert or an empty/undefined function.

    Returns MethodDecorator

Static uninitialize

  • Method decorator for uninitialization of Initializable inheritors. This decorator asserts the initialization status of the instance that is to be uninitialized, invokes its uninitialization, and falsifies the initialization status. In order to encourage the use of assertInitialized and assertUninitialized they are dynamically bound to a static, always-failing assert and an empty/undefined function respectively.

    Returns MethodDecorator
