Rework animation to be done in two phases.

18

# Objective Bevy's animation system currently does tree traversals based on `Name` that aren't necessary. Not only do they require in unsafe code because tree traversals are awkward with parallelism,...

Allow extended materials to exclude `StandardMaterial` inputs that they don't want.

1

This makes it possible to use only portions of `pbr_input_from_standard_material`, which improves ergonomics of common use cases. A simple example is provided that applies a decal to a texture. Possible...

Fix noncomformant behavior by not requiring the `source` field to be present in textures.

1

It's perfectly legal for `source` to not be present. Typically, this will happen when an extension such as `KHR_texture_basisu` provides the actual source. The glTF spec § 5.29 states unambiguously...

Implement clearcoat per the Filament and the `KHR_materials_clearcoat` specifications.

12

Clearcoat is a separate material layer that represents a thin translucent layer of a material. Examples include (from the [Filament spec]) car paint, soda cans, and lacquered wood. This commit...

Implement filmic color grading.

1

This commit expands Bevy's existing tonemapping feature to a complete set of filmic color grading tools, matching those of engines like Unity, Unreal, and Godot. The following features are supported:...

Implement fast depth of field as a postprocessing effect.

5

This commit implements the [depth of field] effect, simulating the blur of objects out of focus of the virtual lens. Either the [hexagonal bokeh] effect or a faster Gaussian blur...

Add `EncasedBufferVec`, an higher-performance alternative to `StorageBuffer`, and make `GpuArrayBuffer` use it.

7

`EncasedBufferVec` is like `BufferVec`, but it doesn't require that the type be `Pod`. Alternately, it's like `StorageBuffer`, except it doesn't allow CPU access to the data after it's been pushed....

Implement opt-in sharp screen-space reflections for the deferred renderer.

7

This commit implements *screen-space reflections* (SSR), which approximate real-time reflections based on raymarching through the depth buffer and copying samples from the final rendered frame. Numerous variations and refinements to...

Implement visibility ranges, also known as hierarchical levels of detail (HLODs).

6

Implement visibility ranges, also known as hierarchical levels of detail (HLODs). This commit introduces a new component, `VisibilityRange`, which allows developers to specify camera distances in which meshes are to...

Implement volumetric fog and volumetric lighting, also known as light shafts or god rays.

6

This commit implements a more physically-accurate, but slower, form of fog than the `bevy_pbr::fog` module does. Notably, this *volumetric fog* allows for light beams from directional lights to shine through,...
