SPYING EYESPROBLEMS

  • The most expressive part of the face

  • People have special sense of eyes

  • Synchronizing eyes movements

  • Real-looking eyes, not cartoon-like ones

SPYING EYESMODEL

  • Using a sphere for the shape

  • Using texture for the details- a hand-made texture- no need to be too detailed

SPYING EYESANIMATION

  • Eye movement- synchronization- close-object focusing (non-parallel look)

  • 3D variant of Logo’s TOWARDS- eigen axis of an object- vector from the eye to the target- individual processing of each of the eyes
