Photo Realistic Rendering

Design And Assembly Chopper:

Objective:

• To design and model the American Chopper using solid.
• Modelling each part of American Chopper.
• Assembling all modelled parts to get the chopper.
• Rendering the American Chopper by applying the required decals as well as appearance
• Build the assembled chopper as photorealistic render in environment by applying accurate scenes.

Introduction:

• Solidworks is a mechanical 3D CAD (Computer Aided Design) Software.
• It is used in designing and modelling wide range of components and parts in realistic appearances and scenes.
• It makes easier for the user to model complicated shapes parts and components through different commands and tools.
• It also provides variety of environments as well colour pallets to make the final model more realistic.
• It also has its own render tool that provide us the final render image of the constructed model.
