Struct MeshLayouts

pub struct MeshLayouts {
    pub model_only: BindGroupLayout,
    pub lightmapped: BindGroupLayout,
    pub skinned: BindGroupLayout,
    pub skinned_motion: BindGroupLayout,
    pub morphed: BindGroupLayout,
    pub morphed_motion: BindGroupLayout,
    pub morphed_skinned: BindGroupLayout,
    pub morphed_skinned_motion: BindGroupLayout,
}

All possible BindGroupLayouts in bevy’s default mesh shader (mesh.wgsl).

Fields

model_only: BindGroupLayout

The mesh model uniform (transform) and nothing else.

lightmapped: BindGroupLayout

Includes the lightmap texture and uniform.

skinned: BindGroupLayout

Also includes the uniform for skinning

skinned_motion: BindGroupLayout

Like MeshLayouts::skinned, but includes slots for the previous frame’s joint matrices, so that we can compute motion vectors.

morphed: BindGroupLayout

Also includes the uniform and MorphAttributes for morph targets.

morphed_motion: BindGroupLayout

Like MeshLayouts::morphed, but includes a slot for the previous frame’s morph weights, so that we can compute motion vectors.

morphed_skinned: BindGroupLayout

Also includes both uniforms for skinning and morph targets, also the morph target MorphAttributes binding.

morphed_skinned_motion: BindGroupLayout

Like MeshLayouts::morphed_skinned, but includes slots for the previous frame’s joint matrices and morph weights, so that we can compute motion vectors.

Implementations

impl MeshLayouts

pub fn new(render_device: &RenderDevice) -> MeshLayouts

Prepare the layouts used by the default bevy Mesh.

pub fn model_only( &self, render_device: &RenderDevice, model: &BindingResource<'_>, ) -> BindGroup

pub fn lightmapped( &self, render_device: &RenderDevice, model: &BindingResource<'_>, lightmap: &GpuImage, ) -> BindGroup

pub fn skinned( &self, render_device: &RenderDevice, model: &BindingResource<'_>, current_skin: &Buffer, ) -> BindGroup

Creates the bind group for skinned meshes with no morph targets.

pub fn skinned_motion( &self, render_device: &RenderDevice, model: &BindingResource<'_>, current_skin: &Buffer, prev_skin: &Buffer, ) -> BindGroup

Creates the bind group for skinned meshes with no morph targets, with the infrastructure to compute motion vectors.

current_skin is the buffer of joint matrices for this frame; prev_skin is the buffer for the previous frame. The latter is used for motion vector computation. If there is no such applicable buffer, current_skin and prev_skin will reference the same buffer.

pub fn morphed( &self, render_device: &RenderDevice, model: &BindingResource<'_>, current_weights: &Buffer, targets: &TextureView, ) -> BindGroup

Creates the bind group for meshes with no skins but morph targets.

pub fn morphed_motion( &self, render_device: &RenderDevice, model: &BindingResource<'_>, current_weights: &Buffer, targets: &TextureView, prev_weights: &Buffer, ) -> BindGroup

Creates the bind group for meshes with no skins but morph targets, in addition to the infrastructure to compute motion vectors.

current_weights is the buffer of morph weights for this frame; prev_weights is the buffer for the previous frame. The latter is used for motion vector computation. If there is no such applicable buffer, current_weights and prev_weights will reference the same buffer.

pub fn morphed_skinned( &self, render_device: &RenderDevice, model: &BindingResource<'_>, current_skin: &Buffer, current_weights: &Buffer, targets: &TextureView, ) -> BindGroup

Creates the bind group for meshes with skins and morph targets.

pub fn morphed_skinned_motion( &self, render_device: &RenderDevice, model: &BindingResource<'_>, current_skin: &Buffer, current_weights: &Buffer, targets: &TextureView, prev_skin: &Buffer, prev_weights: &Buffer, ) -> BindGroup

Creates the bind group for meshes with skins and morph targets, in addition to the infrastructure to compute motion vectors.

See the documentation for MeshLayouts::skinned_motion and MeshLayouts::morphed_motion above for more information about the current_skin, prev_skin, current_weights, and prev_weights buffers.

Trait Implementations

impl Clone for MeshLayouts

fn clone(&self) -> MeshLayouts

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.
