When vibhor calls setMarks, a pointer to vibhor is passed to setMarks telling it that it is object

rt is lies that tell the truth, said Piccaso. Art is art; everything else is everything
else, said Ad Reinhardt. Art completes what nature cannot bring to finish, is an
AAristotle quote.
If art imitates life, one form of such exercise is animation. Peter Ratner’s “3-D Human
Modeling and Animation” has all the tools and know-how “to create digital characters
that can move, express emotions and talk”. The book demonstrates how you can use your
artistic skills in figure drawing, painting, and sculpture to create animated human figures
using the latest computer technology. “No one has been able to make computer graphics
humans that have been mistaken for real ones in movies and photos when viewed at close
range,” states the preface. “Until technology evolves to the point that this becomes possible,
creating an artistic representation of a human is still a worthwhile goal.” A few frames
from the book:

The closer a character becomes to an everyday human, the more ordinary it will appear.
Synthetic humans most often lack personality. Computer characters that try to mimic
human movement through unedited motion-capture techniques generally look like puppets
