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.

Design Methodology/Approach: It is explained by the following flowchart:-

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
• Concentric Mate
• Limit Angle Mate
• Width Mate
• Angle Mate
• Parallel Mate
• Tangent Mate

Photorealistic Rendering and Applying Decal

After the complete assembly of the bike, Decals are applied to the individual part on which it is required. Then Appropriate environment and Cameras at different angles are set. Lighting, Brightness, Reflections, and other parameters are also fine-tuned.

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.
