ApplyPosition

  • ApplyPosition(a_transform: [number, number, number, number, number, number, number, number, number, number, number, number, number, number, number, number] | Float32Array, a_position: [number, number, number] | Float32Array): [number, number, number, number, number, number, number, number, number, number, number, number, number, number, number, number]

  • Moves a transform by a given position, and returns the new transform. The transform is assumed to be a view transform (world->camera space).

    Parameters

    • a_transform: [number, number, number, number, number, number, number, number, number, number, number, number, number, number, number, number] | Float32Array

      The transform.

    • a_position: [number, number, number] | Float32Array

      Offset to move the transform by.

    Returns [number, number, number, number, number, number, number, number, number, number, number, number, number, number, number, number]

    The modified transform.

ApplyPositionLocal

  • ApplyPositionLocal(a_transform: [number, number, number, number, number, number, number, number, number, number, number, number, number, number, number, number] | Float32Array, a_position: [number, number, number] | Float32Array): [number, number, number, number, number, number, number, number, number, number, number, number, number, number, number, number]

  • Moves a transform by a given position, and returns the new transform. The move is in the local space of the transform (e.g. moving along the z-axis will perform the move relative to the transform's local z-axis, not the world z-axis). The transform is assumed to be a view transform (world->camera space).
