Functions

func DefaultMapJointfunc 

func DefaultMapJointfunc(sk *vmodel.Skin, name string) (jIndex int)

Types

type BVHAnimation 

type BVHAnimation struct {
	Root   *BvhJoint
	Joints []*BvhJoint

	Values map[string]float32
	// contains filtered or unexported fields
}

func LoadBVH 

func LoadBVH(l vasset.Loader, filename string) (*BVHAnimation, error)

func (*BVHAnimation) BuildAnimation 

func (bvh *BVHAnimation) BuildAnimation(sk *vmodel.Skin, mj MapJoint) vmodel.Animation

BuildAnimation tries to match skin bones orientation with BVH model orientation in world space for each recorded frame. BuildAnimation will create appropriate rotations to match target BVH bone direction. Therefore BVH will work even if original pose of BVH model and current model are different.

However, currently this will only works if original skin don't have any rotation applied in bone direction and root bone (typically Hips) should have no rotation in pose position. If this not true you will see odd twists at some bones in animated model!

type BvhJoint 

type BvhJoint struct {
	Offset   mgl32.Vec3
	Name     string
	Children []*BvhJoint
	Len      mgl32.Vec3
	// contains filtered or unexported fields
}

func (*BvhJoint) GetPoseRotation 

func (j *BvhJoint) GetPoseRotation() mgl32.Mat4

func (*BvhJoint) GetRotation 

func (j *BvhJoint) GetRotation(frame int) mgl32.Mat4

func (*BvhJoint) GetTranslation 

func (j *BvhJoint) GetTranslation(frame int) mgl32.Mat4

type MapJoint 

type MapJoint func(sk *vmodel.Skin, name string) (jIndex int)
