Unit

type TCastlePerspective = class(TCastleComponent)

Subcomponent used in TCastleCamera.Perspective to set perspective projection parameters.

Do not create instances of this class yourself, these are automatically created by TCastleCamera.

	`property EffectiveFieldOfView: TVector2 read FEffectiveFieldOfView;`
Effective field of view, horizontal and vertical, in radians. Calculated looking at FieldOfView and FieldOfViewAxis, taking into account sizes of the viewport using this camera.

	`property FieldOfView: Single read FFieldOfView write SetFieldOfView stored IsStoredFieldOfView default DefaultFieldOfView;`
Perspective field of view angle, in radians. The FieldOfViewAxis determines whether this is horizontal or vertical angle.

property FieldOfViewAxis: TFieldOfViewAxis read FFieldOfViewAxis write SetFieldOfViewAxis default DefaultFieldOfViewAxis;

Which axis is determined explicitly by FieldOfView.
