Class GeometrySystem

constructor

• new GeometrySystem(renderer): GeometrySystem

• Parameters

  • renderer: Renderer

    The renderer this System works for.

  Returns GeometrySystem

Readonly canUseUInt32ElementIndex

Readonly hasInstance

Readonly hasVao

Readonly managedGeometries

bind

• bind(geometry?, shader?): void

• Binds geometry so that is can be drawn. Creating a Vao if required

  Parameters

  • Optional geometry: Geometry

    Instance of geometry to bind.
  • Optional shader: Shader

    Instance of shader to use vao for.

  Returns void

destroy

• destroy(): void

• Generic destroy methods to be overridden by the subclass

  Returns void

disposeAll

• disposeAll(contextLost?): void

• Dispose all WebGL resources of all managed geometries.

  Parameters

  • Optional contextLost: boolean

    If context was lost, we suppress gl.delete calls

  Returns void

disposeGeometry

• disposeGeometry(geometry, contextLost?): void

• Disposes geometry.

  Parameters

  • geometry: Geometry

    Geometry with buffers. Only VAO will be disposed
  • Optional contextLost: boolean

    If context was lost, we suppress deleteVertexArray

  Returns void

draw

• draw(type, size?, start?, instanceCount?): this

• Draws the currently bound geometry.

  Parameters

  • type: DRAW_MODES

    The type primitive to render.
  • Optional size: number

    The number of elements to be rendered. If not specified, all vertices after the starting vertex will be drawn.
  • Optional start: number

    The starting vertex in the geometry to start drawing from. If not specified, drawing will start from the first vertex.
  • Optional instanceCount: number

    The number of instances of the set of elements to execute. If not specified, all instances will be drawn.

  Returns this

reset

• reset(): void

• Reset and unbind any active VAO and geometry.

  Returns void

updateBuffers

• updateBuffers(): void

• Update buffers of the currently bound geometry.

  Returns void
