Class TrackGeometry

constructor

• new TrackGeometry(contextManager): TrackGeometry

• Parameters

  • contextManager: ContextManager

  Returns TrackGeometry

scaling

addPoint

• addPoint(x, y, z): void

• Parameters

  • x: number
  • y: number
  • z: number

  Returns void

addRef

• addRef(): number

• Increments the reference count of an Shareable instance.

  Returns number

  The new reference count. This value is intended to be used only for testing purposes.

bind

• bind(material): TrackGeometry

• Binds the attributes of the material to the buffers in this Geometry.

  Parameters

  • material: Material

  Returns TrackGeometry

contextFree

• contextFree(): void

• Called to request the consumer to free any WebGL resources acquired and owned. The consumer may assume that its cached context is still valid in order to properly dispose of any cached resources. In the case of shared objects, this method may be called multiple times for what is logically the same context. In such cases the consumer must be idempotent and respond only to the first request.

  Returns void

contextGain

• contextGain(): void

• Called to inform the dependent of a new WebGL rendering context. The implementation should ignore the notification if it has already received the same context.

  Returns void

contextLost

• contextLost(): void

• Called to inform the dependent of a loss of WebGL rendering context. The dependent must assume that any cached context is invalid. The dependent must not try to use and cached context to free resources. The dependent should reset its state to that for which there is no context.

  Returns void

draw

• draw(): TrackGeometry

• A call to drawArrays or drawElements.

  Returns TrackGeometry

erase

• erase(): void

• Returns void

release

• release(): number

• Decrements the reference count of an Shareable instance.

  Returns number

  The new reference count. This value is intended to be used only for testing purposes.

unbind

• unbind(material): TrackGeometry

• Unbinds the attributes of the material from the buffers in this Geometry.

  Parameters

  • material: Material

  Returns TrackGeometry
