Struct RenderMesh

pub struct RenderMesh {
    pub vertex_count: u32,
    pub morph_targets: Option<TextureView>,
    pub buffer_info: RenderMeshBufferInfo,
    pub key_bits: BaseMeshPipelineKey,
    pub layout: MeshVertexBufferLayoutRef,
}

The render world representation of a Mesh.

Fields

vertex_count: u32

The number of vertices in the mesh.

morph_targets: Option<TextureView>

Morph targets for the mesh, if present.

buffer_info: RenderMeshBufferInfo

Information about the mesh data buffers, including whether the mesh uses indices or not.

key_bits: BaseMeshPipelineKey

Precomputed pipeline key bits for this mesh.

layout: MeshVertexBufferLayoutRef

A reference to the vertex buffer layout.

Combined with RenderMesh::buffer_info, this specifies the complete layout of the buffers associated with this mesh.

Implementations

impl RenderMesh

pub fn primitive_topology(&self) -> PrimitiveTopology

Returns the primitive topology of this mesh (triangles, triangle strips, etc.)

Trait Implementations

impl Clone for RenderMesh

fn clone(&self) -> RenderMesh

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for RenderMesh

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl RenderAsset for RenderMesh

fn prepare_asset( mesh: Self::SourceAsset, (images, mesh_vertex_buffer_layouts): &mut SystemParamItem<'_, '_, Self::Param>, ) -> Result<Self, PrepareAssetError<Self::SourceAsset>>

Converts the extracted mesh into a RenderMesh.

type SourceAsset = Mesh

The representation of the asset in the “main world”.

type Param = (Res<'static, RenderAssets<GpuImage>>, ResMut<'static, MeshVertexBufferLayouts>)

Specifies all ECS data required by RenderAsset::prepare_asset.

fn asset_usage(mesh: &Self::SourceAsset) -> RenderAssetUsages

Whether or not to unload the asset after extracting it to the render world.

fn byte_len(mesh: &Self::SourceAsset) -> Option<usize>

Size of the data the asset will upload to the gpu. Specifying a return value will allow the asset to be throttled via RenderAssetBytesPerFrame.
