Enum webrender::spatial_tree::CoordinateSpaceMapping

pub enum CoordinateSpaceMapping<Src, Dst> {
    Local,
    ScaleOffset(ScaleOffset),
    Transform(Transform3D<f32, Src, Dst>),
}

Transformation between two nodes in the spatial tree that can sometimes be encoded more efficiently than with a full matrix.

Variants

Local

ScaleOffset(ScaleOffset)
