Type Alias GpuMeshRefitPlacement

Type Declaration

• Optionalgeneration?: number

• OptionalpositionLayout?: "vec4" | "packed"

  Indexed trees: the positions buffer's layout. Default 'vec4'.

• OptionaltriangleWordOffset?: number

• OptionalvertexBase?: number

  Indexed trees, required: the mesh's first vertex in the target's positions buffer (0 for a tree in its own buffers; meshRefitPlacement for a scene mesh).

• OptionalvertexCount?: number

  Indexed trees: the mesh's vertices there; encode then refuses a posed buffer of another size.

• { nodeFormat?: "f32" | "quantized"; nodeWordOffset?: undefined }

  • OptionalnodeFormat?: "f32" | "quantized"

    The target's node format. Required with nodeWordOffset (a tree inside other buffers, such as a scene's: the target's format is not the layout's; meshRefitPlacement gives it). Without nodeWordOffset (the tree in its own buffers) it defaults to the layout's. With 'quantized', nodeWordOffset is the root's (its frame slot is the 8 words before; default 8), and the refit runs on an f32 copy then packs it into the target.

  • OptionalnodeWordOffset?: undefined

    The tree in its own buffers (word 0; with quantized nodes, its root after the frame slot).

• { nodeFormat: "f32" | "quantized"; nodeWordOffset: number }

  • nodeFormat: "f32" | "quantized"

    The target's node format, required here.

  • nodeWordOffset: number

    Where the mesh's root sits in the target node buffer, in words.
