Variable transforms for three-dimensional engines

Abstract

Disclosed are various embodiments of variable transform systems for three-dimensional engines. In some aspects, a custom transform editor interface overrides a user interface included with a 3D engine to enable interactions according to a non-native coordinate system that is different from a native coordinate system of the 3D engine. An initial mesh that specifies a initial vertex positions is intercepted. The initial mesh is modified into a modified mesh with polygons that are aligned to the non-native coordinate system. The custom transform editor interface renders the modified mesh as polygons that are aligned to the non-native coordinate system rather than the native coordinate system of the 3D engine.
