Photo Realistic Rendering
Title: Modelling 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 (colour & material) to the parts,
adding decals, set up camera, lights & environments, etc. In the end, render realistic photos of
the bike using SOLIDWORKS Visualize.
Introduction: This report is about 3D modelling of the American Chopper Bike using
SOLIDWORKS. SOLIDWORKSB is a 3D CAD software that is used to create 3D CAD
models of different types of products which consist of solid modelling, Surfacing, Sheet
Metal, Weldments, etc. The modelling of different parts of the bike is done using various
feature 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 modelling all the parts individually, all the parts are assembled together using
Appropriate mates.
Following are the tools and feature which are used for assembly: -
- Coincident Mate
- Distance Mate
- Concentric Mate
- Limit Angle Mate
- Width Mate
- Angle Mate
- Parallel Mate
- Tangent Mate
Camera Setup
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 if you are not satisfied with
the default setting. When everything is set rendering is done with different environment,
colour, and angles.
Conclusion: The design of the American Chopper Bike helped to understand various tools of
SOLIDWORKS. We got to learn about Solid Modelling, Surfacing, how to handle splines,
Of the bike and later render the assembled bike with appropriate Colour, Materials, Decals,
Environment, Lighting, Cameras Setup, etc.
