Detailed Description

This class implements a constraint object in Clarisse.
A constaint is an embedded object that modifies the matrix of an item.

Member Function Documentation

bool ModuleConstraint::apply_constraint	(	const ModuleSceneItemInfo &	item,
		GMathMatrix4x4d &	global_xform
	)		const

Applies the constraint: computes the global matrix of the item.

Parameters

[in]	item	Scene item information.
[out]	global_xform	Output matrix.

bool ModuleConstraint::apply_constraint_at	(	const double &	time,
		const ModuleSceneItemInfo &	item,
		GMathMatrix4x4d &	global_xform
	)		const

Applies the constraint at a specified time.

Parameters

[in]	time	Time at which the constraint needs to be evaluated.
[in]	item	Scene item information.
[out]	global_xform	Output matrix.
