Slicer

The slicer is a tool within the Virtual Anatomy that is designed to reveal cross-sections of 3D anatomical models by cutting through them visually. It helps explore internal structures by adjusting the slicing plane’s position and orientation. The slicing effect is achieved through a material setup that uses real-time parameters such as the plane’s location, direction, and activation state.

To support this functionality, the class ACPP_Slicer provides the logic that drives the slicer. It handles updates to the slicing plane’s transform, communicates with the material system through a Material Parameter Collection (MPC), and saves or restores slicer settings like position, rotation, and enabled state via UCPP_GameInstance.

This code logic is applied through the Blueprint BP_Slicer, which is placed in explorer levels where slicing functionality is required. BP_Slicer already includes the necessary Plane and SpringArm components preconfigured for use and those are not created inside the code.

Warning

If BP_Slicer is not present in one of the Explorer levels or ACPP_Slicer throws any error, the slicer functionality will be disabled and unavailable. This means slicing-related controls in the UI will disappear, and materials relying on slicer parameters will not display any slicing behavior.
