Function Documentation

errorHandler()

void errorHandler	(	void *	ctx,
		const char *	msg,
			...
	)

Error handler for libxml2.

FindInstances()

static void FindInstances ( FCDSceneNode *  node, std::vector< FoundInstance > &  instances, const FMMatrix44 &  transform, bool  onlyMarked  )

static

Recursively finds all entities under the current node.

If onlyMarked is set, only matches entities where the user-defined property was set to "export" in the modelling program.

Parameters

node	root of subtree to search
instances	output - appends matching entities
transform	transform matrix of current subtree
onlyMarked	only match entities with "export" property

FindSingleInstance()

bool FindSingleInstance	(	FCDSceneNode *	node,
		FCDEntityInstance *&	instance,
		FMMatrix44 &	transform
	)

Tries to find a single suitable entity instance in the scene.

Fails if there are none, or if there are too many and it's not clear which one should be converted.

Parameters

node	root scene node to search under
instance	output - the found entity instance (if any)
transform	- the world-space transform of the found entity

Returns

true if one was found

FindSkeleton()

const Skeleton & FindSkeleton

(

const FCDControllerInstance &

controllerInstance

)

Finds the skeleton definition which best matches the given controller.

Exceptions

ColladaException

if none is found.

FixSkeletonRoots()

void FixSkeletonRoots

(

FCDControllerInstance &

controllerInstance

)

Fixes some occasional problems with the skeleton root definitions in a controller.

(In particular, it's needed for models exported from XSI.) Should be called before extracting any joint information from the controller.

FMMatrix44_Identity()

FMMatrix44 FMMatrix44_Identity

(

identity

)

FMVector3_XAxis()

const FMVector3 FMVector3_XAxis	(	1.	0f,
		0.	0f,
		0.	0f
	)

IsVisible()

static bool IsVisible ( FCDSceneNode *  node )

static

IsVisible_XSI()

static bool IsVisible_XSI ( FCDSceneNode *  node, bool &  visible  )

static

require_()

void require_	(	int	line,
		bool	value,
		const char *	type,
		const char *	message
	)

ReverseSortWeight()

static bool ReverseSortWeight ( const FCDJointWeightPair &  a, const FCDJointWeightPair &  b  )

static

SkinReduceInfluences()

void SkinReduceInfluences	(	FCDSkinController *	skin,
		size_t	maxInfluenceCount,
		float	minimumWeight
	)

Like FCDSkinController::ReduceInfluences but works correctly.

Additionally, multiple influences for the same joint-vertex pair are collapsed into a single influence.

TransformBones()

void TransformBones	(	std::vector< BoneTransform > &	bones,
		const FMMatrix44 &	scaleTransform,
		bool	yUp
	)

Performs the standard transformations on bones, applying a scale matrix and moving them into the game's coordinate space.
