Detailed Description

Each x file model must has a skeleton(including static object) A skeleton contains a collection of bones.

call CalcTransformMatrix() to update the bone matrix call GetTransformMatrix() for a weighted sum of a bone groups.(skinned animation)

Member Function Documentation

GetTransformMatrix()

float CSkeleton::GetTransformMatrix	(	D3DXMATRIX &	mat,
		float &	animAlpha,
		int *	index,
		int	count
	)

call this function to get the matrix for a weighted sum of a group of bones.

this is for skinned animation.

it is assumed that weight of multiple bones are evenly distributed.

ReadPivotPoints()

void CSkeleton::ReadPivotPoints	(	TypePointer	inP,
		int	inSize
	)

set offset matrix for each bone set the animation translation keyframe for each bone

set the offset matrix to be a translation matrix of the negation of the pivot point

set the translation animation keyframe so that a component of Pivot[i]-Pivot[i-1] is added to each translation key. If there is no key, we will add one.
