Bipedal Human Gait : A 3d Interactive Model with Animation

Human Gait Analysis with motion capture video systems and interactive 3d modeling systems help doctors analyze, diagnose, and document aberrant gaits with tools that compare the gaits of patients before and after treatment to historical case studies of normal and abnormal gaits.   This   interactive 3d model   animates a normal adult male gait, a video motion capture system at a medical research laboratory collected the data.

  You can rotate the 3d model, and start and stop the animation.

The 3d model can be  scaled, rotated, and translated  ( moved )   See below.

Better model needed ?   Find out how to animate VRML models, create ".mov" videos with Java3d, VRML, and the Java JMF View video clips of the model created with Java3d View the VRML 3d model ( plug-in required ) Resources, Tutorials, etc.     These images were created with Java3d & VRML

  Need Speed ?   Need a more detailed model ?   Java3d is faster and it can use hardware graphics accelerators.

Instructions :

• To   Rotate, Scale, and Translate  use the sliders and dials.
• Mouse Actions on Animation Canvas

  ( _ - )	Rotate around the vertical axis	Left Button
  ( - _ )	Translate Eye up / down; object Left / Right	Right Button
  ( _ - )  [ Ctrl ]	Zoom in out	[ Crl button ] and any Mouse Button
  ( _ - )  [ Alt  ]	---	[ Alt Button ] and any Mouse Button

• Change gait data ( joint rotation data sets ) with the Choise List.
• Choose between 3d, 2d, 2d & 3d the other Choice List.

This is a partial implementation of a richer 3d animation program.

Esthetics are generally secondary technical considerations at this point, but even this rough animation provides considerable guidance to me.

I'm not striving for realism; as a skilled artist can capture the essense of person with few sketched lines, I'm seeking a minimalist solution that is pleasing and is accessable to the largest possible audience which implies Java and simple models.

On the other hand, you and I have 206 bones, so I'll create a 'true' human skeleton for educational purposes.

Future Features :

• higher resolution model, more joints
• A rich set of   'activities' ( movements ) appropriate to the character.
• Allowing models to be added to the program while it runs ( with tree structures ).
• VRML linkages : controlling VRML models, reading VRML files.
• View multiple ".mov" video clips with speed control  with the Java Media Framework.
