You can calculate 2D coordinate transformations using matrix operations to apply, decompose, or invert transforms, alongside toGlobal and toLocal functions for converting coordinates across containers and scenes.
Hit-testing against shapes like polygons, circles, and rectangles is handled by applying shape primitives to define precise hit areas and calculate intersections for interactive containers.
Yes, PixiJS includes Point and ObservablePoint primitives, rectangle layout helpers, and math-extras utilities to perform extended vector operations and layout calculations.
Global to local coordinate conversions are performed using matrix transforms and inverse calculations to accurately map scene points to the local space of nested sprites and containers.
Matrix decomposition is needed when separating a composite 2D transform into its translation, rotation, and scale components to manipulate individual properties of sprites and shapes.
