FConeData

Overview

FConeData is a struct that encapsulates the properties of a cone. It provides methods to calculate various geometric properties such as the base center point, hypotenuse length, volume, and radius at a given height. The class uses lazy evaluation for these properties to ensure they are only computed when necessary.

Properties

Type	Name	Access	Description
FVector	Apex	Public	The apex point of the cone.
FQuat	Orientation	Public	The orientation of the cone.
float	Angle	Public	The full angle of the cone in degrees.
float	Height	Public	The height of the cone.
FVector	BaseCenterPoint	Private	Lazy-evaluated base center point of the cone.
float	HypotenuseLength	Private	Lazy-evaluated length of the cone's hypotenuse.
float	Volume	Private	Lazy-evaluated volume of the cone.
float	BaseRadius	Private	Lazy-evaluated radius of the cone at its base.

Functions

Return Type	Signature	Description
FConeData	FromAngle(const FVector& InApex, const FQuat& InOrientation, const float InAngle, const float InHeight)	Creates a new `FConeData` instance from the given apex, orientation, angle, and height.
bool	IsPossible() const	Checks if the cone data is valid (non-zero apex or non-zero angle/height).
FVector	GetApex() const	Returns the apex point of the cone.
FQuat	GetOrientation() const	Returns the orientation of the cone.
float	GetAngle() const	Returns the full angle of the cone in degrees.
float	GetHeight() const	Returns the height of the cone.
FVector	GetBaseCenterPoint() const	Returns the base center point of the cone, lazily evaluated.
FVector	GetSafeBaseCenterPoint() const	Returns a safe base center point of the cone.
float	GetHypotenuseLength() const	Returns the length of the cone's hypotenuse, lazily evaluated.
float	GetVolume() const	Returns the volume of the cone, lazily evaluated.
float	GetBaseRadius() const	Returns the radius of the cone at its base, lazily evaluated.
float	GetRadiusAtHeight(const float TestHeight) const	Returns the radius of the cone at a given height.

Usage & Implementation Notes

The FConeData struct uses lazy evaluation for properties like BaseCenterPoint, HypotenuseLength, Volume, and BaseRadius to optimize performance by avoiding unnecessary calculations.
The GetBaseCenterPoint function includes a safety check to ensure the base center point is only computed once.
