Photo Realistic Rendering

Modeling and Rendering of American Chopper

Objective

     The objective of this project is to design and model the various parts of the American Chopper using Solidworks. To assemble the modeled components and apply decals. Adding in the camera, lights, scene and environment. Finally, rendering the assembly of the chopper in Solidworks PhotoView 360 and Solidworks Visualise.

Introduction

     This report contains all the details about the chopper, from the designing and rendering of each individual part to the final rendering of the chopper assembly.

The American chopper parts to be modeled include:

1. Transmission Belt
2. Kick Stand
3. Front Fender
4. Rear Fender
5. Front Wheel
6. Rear Wheel
7. Engine
8. Chain
9. Oil Tank
10. pedal
11. Front Fork
12. Chassis
13. Gas Tank

     Solidworks is used throughout the entire process, which is a solid modeling Computer-Aided Design (3D CAD) software.

14. Assembly

     Tools/ Features used

• Insert Components: Inserting in all the parts we modeled
• Mates: To create constraints between each part and planes like coincident, parallel, concentric, width mate, etc. Also making the required part fixed

Rendering

     PhotoView 360 and SOLIDWORKS Visualize are used for rendering the assembled model.

Rendering in PhotoView 360

     Rendering the assembly in Solidworks with the help of PhotoView 360. PhotoView 360 is a Solidworks add-in that is used to produce photo-realistic renderings of a created model. The rendering tools help to enhance and produce a realistic chopper model with any scene and environment.

Tools/ Features used

• Camera: Adding a camera view according to our liking
• Scene: Setting up scene and environment
• Lights: Adjusting lights if necessary
• Render Preview: To preview the render before the final render
• Schedule Render: To schedule a specific time at with the rendering of the model starts
• Final Render: To render the finalized model 

Solidworks Visualise

     Solidworks Visualize is also a rendering software used only for rendering purposes. It creates a better render than the rendering in the Solidworks PhotoView 360.

Conclusion

     The 3D model of American Chopper is ready from designing each part to assembling each part and is given a realistic look using renders.
