Visual Realism is a method for interpreting picture data fed into a computer and for creating pictures from difficult multidimensional data sets.

Visualization can be classified as:

• Visualization in geometric modeling

• Visualization in scientific computing.

Visualization in geometric modeling is helpful in finding connection in the design applications. By shading the parts with various shadows, colors and transparency, the designer can recognize undesired unknown interferences. In the design of complex surfaces shading with different texture characteristics can use to find any undesired quick modifications in surface changes. Visualization in computing is viewed as a technique of geometric modeling. It changes the data in numerical form into picture display, allowing users to view their simulations and computations. Visualization offers a process of seeing the hidden. Visualization in scientific computing is of great interest to engineers during the design process.

Existing visualization methods are:

• Parallel projections

• Perspective projection.

• Hidden line removal

• Hidden surface removal

• Hidden solid removal
