Aristotle emphasized the art is realer than reality on the basis of the theory of Imitation;Wilde meaned that the art should be far away from the reality;Baudrillard put forward the theory of simulacrum and meaned that the art create the reality and dispel the reality.

Its intersubjectivity,simulacrum,and virtual experience have a new theoretic character.

The former refers to the massive multiplication of the simulacrum while th.

Multiaspect and multi-scale-based contour noise image simulation;

A new image simulation algorithm for three dimensional grain growth of polycrystalline materials is built.

An image simulation system of dynamic infrared point targets sweeping on sea surface is established.

The development of imaging simulation is introduced and the principle of optical remote sensing is studied in the paper.

This paper described the method of modeling real effect in imaging simulation based on Vega,introduced the basic functions of Vega and its sensor modules,discussed the common flow of simulating photoelectric imaging process,investigated how to create the nearly real effect concretely,at last provided the simulation results and compared them with the experiment results.

The simulated sculptures made of Si rubber are uniform color, true to life, high strength, easy to be pecked and transported, convenient to be cleaned and adaptive to various adverse circumstances.
