virtual FVec3 FindGeometryOpposingNormal

const FVec3 & DenormDir,
int32 FaceIndex,
const FVec3 & OriginalNormal
&41; const
Remarks
Given a normal and a face index, compute the most opposing normal associated with the underlying geometry features. For example a sphere swept against a box may not give a normal associated with one of the box faces. This function will return a normal associated with one of the faces. The most opposing normal associated with the underlying geometry's feature (like a face)
Parameters
| Name | Description |
|---|---|
| DenormDir | the direction we want to oppose |
| FaceIndex | the face index associated with the geometry (for example if we hit a specific face of a convex hull) |
| OriginalNormal | the original normal given by something like a sphere sweep |
