Customer Impact
#110050. Customers using
Matrix4x4.CreateReflectionmay see incorrect results on some hardware.Regression
#103527. The code was updated to be accelerated and had an edge case where all components were scaled by
-2instead of just theX, Y, and Zcomponents.Testing
An explicit test covering the scenario where the
Wcomponent was non-zero was added.Risk
Low. This is in an API that is primarily used in specialized scenarios.
