Overview

Methods

	`procedure LoadFromElement(const E: TDOMElement); override;`
	`procedure SaveToStream(const Stream: TStream); override;`
	`function Point(const t: Float): TVector3; override;`
	`function BoundingBox: TBox3D; override;`

Properties

	`property XFunction: TCasScriptExpression index 0 read GetFunction write SetFunction;`
	`property YFunction: TCasScriptExpression index 1 read GetFunction write SetFunction;`
	`property ZFunction: TCasScriptExpression index 2 read GetFunction write SetFunction;`

Description

Methods

	`procedure LoadFromElement(const E: TDOMElement); override;`

	`procedure SaveToStream(const Stream: TStream); override;`

	`function Point(const t: Float): TVector3; override;`

	`function BoundingBox: TBox3D; override;`
Simple bounding box. It is simply a `BoundingBox` of Point(i, SegmentsForBoundingBox) for i in [0 .. SegmentsForBoundingBox]. Subclasses may override this to calculate something more accurate.

	`constructor Create;`

	`destructor Destroy; override;`

Properties

	`property XFunction: TCasScriptExpression index 0 read GetFunction write SetFunction;`
`XFunction`, YFunction, ZFunction are functions based on variable 't'. Once set, these instances become owned by this class, do not free them yourself!

	`property YFunction: TCasScriptExpression index 1 read GetFunction write SetFunction;`

	`property ZFunction: TCasScriptExpression index 2 read GetFunction write SetFunction;`

	`property TVariable: TCasScriptFloat read FTVariable write SetTVariable;`
This is the variable controlling 't' value, embedded also in XFunction, YFunction, ZFunction. This is NOT owned by this class, make sure to free it yourself!

	`property SegmentsForBoundingBox: Cardinal read FSegmentsForBoundingBox write SetSegmentsForBoundingBox default 100;`
