addAttribute

• addAttribute(id, buffer, size?, normalized?, type?, stride?, start?, instance?): this

• Adds an attribute to the geometry Note: stride and start should be undefined if you dont know them, not 0!

  Parameters

  • id: string

    the name of the attribute (matching up to a shader)
  • buffer: number[] | Float32Array | Uint32Array | Buffer

    the buffer that holds the data of the attribute . You can also provide an Array and a buffer will be created from it.
  • Optional size: number

    the size of the attribute. If you have 2 floats per vertex (eg position x and y) this would be 2
  • Optional normalized: boolean

    should the data be normalized.
  • Optional type: TYPES

    what type of number is the attribute. Check PIXI.TYPES to see the ones available
  • Optional stride: number

    How far apart, in bytes, the start of each value is. (used for interleaving data)
  • Optional start: number

    How far into the array to start reading values (used for interleaving data)
  • Optional instance: boolean

    Instancing flag

  Returns this

  • Returns self, useful for chaining.

addIndex

• addIndex(buffer?): Geometry

• Adds an index buffer to the geometry The index buffer contains integers, three for each triangle in the geometry, which reference the various attribute buffers (position, colour, UV coordinates, other UV coordinates, normal, …). There is only ONE index buffer.

  Parameters

  • Optional buffer: number[] | IArrayBuffer | Buffer

    The buffer that holds the data of the index buffer. You can also provide an Array and a buffer will be created from it.

  Returns Geometry

  • Returns self, useful for chaining.

clone

• clone(): Geometry

• Returns a clone of the geometry.

  Returns Geometry

  • A new clone of this geometry.

destroy

• destroy(): void

• Destroys the geometry.

  Returns void

dispose

• dispose(): void

• Disposes WebGL resources that are connected to this geometry.

  Returns void

getAttribute

• getAttribute(id): Attribute

• Returns the requested attribute.

  Parameters

  • id: string

    The name of the attribute required

  Returns Attribute

  • The attribute requested.

getBuffer

• getBuffer(id): Buffer

• Returns the requested buffer.

  Parameters

  • id: string

    The name of the buffer required.

  Returns Buffer

  • The buffer requested.

getIndex

• getIndex(): Buffer

• Returns the index buffer

  Returns Buffer

  • The index buffer.

getSize

• getSize(): number

• Get the size of the geometries, in vertices.

  Returns number

interleave

• interleave(): Geometry

• This function modifies the structure so that all current attributes become interleaved into a single buffer This can be useful if your model remains static as it offers a little performance boost

  Returns Geometry

  • Returns self, useful for chaining.

Static merge

• merge(geometries): Geometry

• Merges an array of geometries into a new single one.

  Geometry attribute styles must match for this operation to work.

  Parameters

  • geometries: Geometry[]

    array of geometries to merge

  Returns Geometry

  • Shiny new geometry!
