�Topic: Morphing

� Seamlessly changing from one mesh to another

� Combining vertices to find a point in between

� Given 2 mouth poses, a set of difference vectors is computed to control interpolation

� In morph targets, the difference vectors are used to add movement to the neutral face.

� Human Computer Interaction

� Understanding and Response� Inputs:

� Natural language (text and speech)� Vision (Images and Video)� Sensors (heart rate, temperature)� Other: smell??

� Understanding:� AI

� Response� Physical – Robots � Speech Synthesis� Virtual – Graphics (Facial Expressions of emotions)

� Use Morphing with shaders to render facial expressions and control via keyboard

� Use cube mapping to create a nice background to simulate Virtual World

� Create morph targets in blender (uses same mesh with different facial expressions)

� Morph Data structure (similar to obj data structure but bigger)

� Load all data

� Link attributes to shaders

� Compute difference vector between neutral pose and target

� Use Weights to adjust the deformation

� Render

� Only 16 attributes

� Real-time Rendering
