Struct RenderMeshInstanceGpuBuilder

pub struct RenderMeshInstanceGpuBuilder {
    pub shared: RenderMeshInstanceShared,
    pub world_from_local: Affine3,
    pub lightmap_uv_rect: UVec2,
    pub previous_input_index: Option<NonMaxU32>,
    pub mesh_flags: MeshFlags,
}

Information that is gathered during the parallel portion of mesh extraction when GPU mesh uniform building is enabled.

From this, the MeshInputUniform and RenderMeshInstanceGpu are prepared.

Fields

shared: RenderMeshInstanceShared

Data that will be placed on the RenderMeshInstanceGpu.

world_from_local: Affine3

The current transform.

lightmap_uv_rect: UVec2

Four 16-bit unsigned normalized UV values packed into a UVec2:

                        <--- MSB                   LSB --->
                        +---- min v ----+ +---- min u ----+
    lightmap_uv_rect.x: vvvvvvvv vvvvvvvv uuuuuuuu uuuuuuuu,
                        +---- max v ----+ +---- max u ----+
    lightmap_uv_rect.y: VVVVVVVV VVVVVVVV UUUUUUUU UUUUUUUU,

(MSB: most significant bit; LSB: least significant bit.)

previous_input_index: Option<NonMaxU32>

The index of the previous mesh input.

mesh_flags: MeshFlags

Various flags.
