Computer Graphics

• Definition combining hardware approaches with
  software algorithms to facilitate the
  manipulation of visual information.
• Subareas
• hardware and system architecture,
• image synthesis,
• animation,
• applications.
• 3D graphics main tasks
• modeling, rendering, animation.

Polynocular Stereo

• From images to 3D points, and then. to planar
  patches

7
Surface Reconstruction and the Gauss map

• From patches to surface
