Material constructor
Renderer class object or GPUCurtains class object used to create this Material.
parameters used to create our Material.
The type of the Material.
ReadonlyuuidThe universal unique id of the Material.
The Renderer used.
Options used to create this Material.
Pipeline entry used by this Material.
Array of bind groups used by this Material. This array respects a specific order:
Array of texture bind groups used by this Material.
Array of bind groups created using the uniforms and storages parameters when instancing this Material.
Array of cloned bind groups created by this Material.
Object containing all uniforms inputs handled by this Material.
Object containing all read only or read/write storages inputs handled by this Material.
Array of Texture or MediaTexture handled by this Material.
Get whether the renderer is ready, our pipeline entry and pipeline have been created and successfully compiled.
Get the main texture bind group created by this Material to manage all textures related struct.
Set or reset this Material renderer. Also reset the bindGroups renderer.
New Renderer or GPUCurtains instance to use.
Set the pipelineEntry.
Check if all bind groups are ready, and create them if needed.
Called when the device has been restored to recreate our samplers, textures and bind groups.
Get the complete code of a given shader including all the WGSL fragment code snippets added by the pipeline. Can wait for the pipelineEntry to be compiled if that's not already the case.
OptionalshaderType: FullShadersType = 'full'
Shader to get the code from.
Get the added code of a given shader, i.e. all the WGSL fragment code snippets added by the pipeline. Can wait for the pipelineEntry to be compiled if that's not already the case.
OptionalshaderType: FullShadersType = 'vertex'
Shader to get the code from.
Prepare and set our bind groups based on inputs and bindGroups Material parameters.
Create the bind groups if they need to be created.
Clones a BindGroup from a list of buffers. Useful to create a newBindGroup with already created buffers, but swapped.
parameters used to clone the BindGroup.
OptionalbindGroup?: AllowedBindGroupsthe BindGroup to clone.
Optionalbindings?: BindGroupBindingElement[]our input binding buffers.
OptionalkeepLayout?: booleanwhether we should keep original bind group layout or not.
Get a corresponding BindGroup or TextureBindGroup from one of its binding name/key
the binding name/key to look for.
Destroy a BindGroup, only if it is not used by another object.
BindGroup to eventually destroy.
Destroy all BindGroup.
Update all BindGroup.
Look for a binding by name in all input bindings
the binding name or key.
Look for a buffer binding by name in all input bindings.
The binding name or key.
Force setting a given buffer binding shouldUpdate flag to true to update it at next render.
OptionalbufferBindingName: string
The buffer binding name.
OptionalbindingName: string
The binding name.
Prepare our textures array and set the TextureBindGroup.
Add a MediaTexture or Texture to our textures array, and add it to the textures bind group only if used in the shaders (avoid binding useless data).
MediaTexture or Texture to add.
Destroy a MediaTexture or Texture, only if it is not used by another object or cached.
MediaTexture or Texture to eventually destroy.
Destroy all the Material textures.
Map a Buffer's GPU buffer and put a copy of the data into a Float32Array
Map the content of a BufferBinding GPU buffer and put a copy of the data into a Float32Array.
The name of the input bindings from which to map the GPU buffer.
Map the content of a specific buffer element belonging to a BufferBinding GPU buffer and put a copy of the data into a Float32Array.
Parameters used to get the result.
The name of the input bindings from which to map the GPU buffer.
The name of the buffer element from which to extract the data afterwards.
Called before rendering the Material. First, check if we need to create our bind groups or pipeline. Finally, updates all the bind groups.
Use the renderer pipelineManager to only set the bind groups that are not already set.
Current pass encoder.
Render the material if it is ready: Set the current pipeline and set the bind groups.
Current pass encoder.
Destroy the Material.
Used as a base to create a Material.
The purpose of Material is to create and update the bind groups and their bindings (GPU buffers, textures and samplers), create a PipelineEntry and use them to render.
Bind groups
A Material automatically creates a TextureBindGroup, but it is actually added to the active bind groups array only if necessary, which means if your shaders use a GPUSampler, a GPUTexture or a GPUExternalTexture.
Another BindGroup will be created if you pass any uniforms or storages parameters.
Finally, you can also pass already created BindGroup to a Material via the bindGroups parameter.
Note that this class is not intended to be used as is, but as a base for ComputeMaterial and RenderMaterial classes.
