Options used to create this GPURenderer
The render pass used to render our result to screen
Additional render pass used by ShaderPass for compositing / post processing. Does not handle depth
The Scene used
Whether we should render our GPURenderer or not. If set to false, the render hooks onBeforeCommandEncoderCreation, onBeforeRenderScene, onAfterRenderScene and onAfterCommandEncoderSubmission won't be called, the scene graph will not be updated and the scene will not be rendered, completely pausing the renderer. Default to true.
Whether we should explicitly update our Scene or not. If set to false, the scene graph will not be updated and the scene will not be rendered. Default to true.
An array containing all our created ComputePass
An array containing all our created PingPongPlane
An array containing all our created ShaderPass
An array containing all our created RenderTarget
An array containing all our created meshes
An array containing all our created Texture
Pixel ratio to use for rendering
An object defining the width, height, top and left position of the canvas. Mainly used internally. If you need to get the renderer dimensions, use boundingRect instead.
DOMElement that will track our canvas container size
Allow to add callbacks to be executed at each render before the GPUCommandEncoder is created
Allow to add callbacks to be executed at each render after the GPUCommandEncoder has been created but before the Scene is rendered
Allow to add callbacks to be executed at each render after the GPUCommandEncoder has been created and after the Scene has been rendered
Allow to add callbacks to be executed at each render after the Scene has been rendered and the GPUCommandEncoder has been submitted
function assigned to the resizeObjects callback
function assigned to the resizeObjects callback
function assigned to the onAfterResize callback
function assigned to the onAfterResize callback
Get our DOM Element bounding rectangle. If there's no DOM Element (like when using an offscreen canvas for example), the rectBBox values are used.
Get our device
Get whether our GPUDeviceManager is ready (i.e. its adapter and device are set) its context is set and its size is set
Get our GPUDeviceManager production flag
Get all the created GPU buffers
Get the pipeline manager
Get all the rendered objects (i.e. compute passes, meshes, ping pong planes and shader passes) created by the GPUDeviceManager
Get all created bind group tracked by our GPUDeviceManager
Get all created DOMTexture tracked by our GPUDeviceManager
Get all this GPURenderer rendered objects (i.e. compute passes, meshes, ping pong planes and shader passes)
function assigned to the onBeforeRender callback
function assigned to the onAfterRender callback
Set the renderer RectBBox and canvas sizes
Set the renderer pixel ratio and resize it
new pixel ratio to use
Resize our GPURenderer
Resize all tracked objects (textures, render passes, render targets, compute passes and meshes).
Resize the meshes.
Clamp to max WebGPU texture dimensions
width and height dimensions to clamp
Configure our context with the given options
Set our context if possible and set main render pass and scene
Called when the device is lost. Force all our scene objects to lose context.
Called when the device should be restored. Configure the context again, resize the render targets and textures, restore our rendered objects context.
Set our main render pass that will be used to render the result of our draw commands back to the screen and our postprocessing pass that will be used for any additional postprocessing render passes.
Set our scene

Check if a Sampler has already been created with the same parameters. Use it if found, else create a new one and add it to the samplers array.
Remove a Sampler from our samplers array
Set different tasks queue managers to execute callbacks at different phases of our render call:
Get all objects (rendered meshes or compute passes) using a given bind group. Useful (but slow) to know if a resource is used by multiple objects and if it is safe to destroy it or not.
bind group to check
Get all objects (rendered meshes or compute passes) using a given DOMTexture or Texture. Useful to know if a resource is used by multiple objects and if it is safe to destroy it or not.

Optional commandEncoder: GPUCommandEncoderAssign a callback function to _onAfterRenderCallback
callback to run just after the render method has been executed

Render an array of objects (either Meshes or ComputePass) once. This method won't call any of the renderer render hooks like onBeforeRender, onAfterRender

Destroy our GPURenderer and everything that needs to be destroyed as well
Base renderer class, that could technically be used to render compute passes and draw fullscreen quads, even tho it is strongly advised to use at least the GPUCameraRenderer class instead. A renderer is responsible for:
