[−]Struct gdnative::common::euclid::TypedTransform2D
A 2d transform stored as a 3 by 2 matrix in row-major order in memory.
Transforms can be parametrized over the source and destination units, to describe a
transformation from a space to another.
For example, TypedTransform2D<f32, WorldSpace, ScreenSpace>::transform_point4d
takes a TypedPoint2D<f32, WorldSpace>
and returns a TypedPoint2D<f32, ScreenSpace>
.
Transforms expose a set of convenience methods for pre- and post-transformations. A pre-transformation corresponds to adding an operation that is applied before the rest of the transformation, while a post-transformation adds an operation that is applied after.
