Photo Realistic Rendering

                                                                       Title: Modeling, Assembly & Photorealistic Rendering of American Chopper.

Objective:

To model parts of the American Chopper Bike using solidworks . Later
assemble all the parts together, give the proper appearance (color & material) to the parts,
adding decals, set up cameras, lights & environment, etc. In the end, render realistic photos of
the bike using solidworks Visualize.

Introduction:

This report is about 3D modeling of the American Chopper Bike using
solidworks. solidworks is a 3D CAD software that is used to create 3D CAD
models of different types of products which consist of solid modeling, Surfacing, Sheet
Metal, Weldments, etc. The modeling of different parts of the bike is done using various
features and given an appropriate appearance individually. Later all the parts are assembled
together using proper mates. Then the assembly is rendered with realistic environment.

Assembly of American Chopper Bike

After modeling all the parts individually, all the parts are assembled together using
appropriate mates.
Following are the different mates which are used for assembly:-
• Coincident Mate
• Distance Mate

Conclusion:

The design of the American Chopper Bike helped to understand various tools of
solidworks. We got to learn about Solid Modeling, Surfacing, how to handle splines,
and many more other things. We have also learned about various mates used in the assembly
of the bike and later render the assembled bike with appropriate Color, Materials, Decals,
Environment, Lighting, Camera Setup, etc.
