Motion is achieved using the following techniques:
Rotoscopy, or drawing on top of a series of real life pictures. In this case, a sequence of pictures is traced by the software "Rotoscope" which is similar to the one used in the film "Waking Life". Lips maybe overimposed by importing the animated sequence in blender and an additional layer with the lip footage. Then exported as an exr animated sequence and mapped as a texture over a mesh2 object in Povray. More elements may be added to the scene and then raytraced and rendered.
Motion capture, using available pre recorded motion capture objects "bvh", imported and textured on either Truespace or Blender.
Computed tweening or creating a skeleton or inorganic object and set the tweening using keyframing. This technique is used only in discreet scenes where the motion is not the point of attention.
Hand drawing, or classical animation, where an animated sequence is drawn on paper, scanned, painted by digital ink on Gimp and tweened with a morphing software to create the in between images. Imported in Cinepaint(Glasgow) and color/image corrected and saved again as a 32 bit per channel exr image. Later mapped either in Truespace, Blender or Povray as a texture over a plane and raytraced.
layer represent a single move,
in the same way as a cell would be photographed by a 35 mm camera.
