Class IndirectBuffer

Utility to handle indirect drawing.

Create a buffer, fill it with all the added geometries attributes and tell all the geometries to start using this buffer for indirect drawing.

Example

const geometry = new Geometry()

// assuming 'renderer' is a valid renderer or curtains instance
const indirectBuffer = new IndirectBuffer(renderer, {
  label: 'Custom indirect buffer',
  geometries: [geometry]
})

// if every geometries have been added, create the buffer.
indirectBuffer.create()

// from now on, any Mesh using 'geometry' as geometry will be rendered using indirect drawing.
