Bicubic Bezier Patches

Name of File containing main

• Source.cpp

Name of File with line numbers implementing SURFACE NORMAL

• Source.cpp: 408 - 745

Details

• The code is implemented as modular as possible and command-line arguments are set as parameters to Parameters Class
• bezier is the function which implements the general bi-cubic bezier patch equation
• computeSum implements the sum part of the equation
• convertNorm1 & convertNorm2 are used to generate Tangents
• normal is the function to generate normals
• flatshade is the function for the general Triangle Indices
• Additional Functions are present to print out the curve coordinates and Input points to the console in .iv format
• The file patchPoints.txt contains some default point options
• filename.txt consists of the other example given in the specification of the Assignment. You could use/modify those example files itself and run

Programming Language and OS

• The code is implemented in C++ on the tux (Linux) platform and would require the g++ compiler to compile

Instructions

• cd into the directory of the folder containing Source.cpp and type make
• Type in make to compile. This produces an executable of the format CG_hw3
• Type in ./CG_hw3 [command-line parameters][-f filename.txt -u num_u -v num_v -r radius [-S or -F]] to run the code
• Follow the run-time command by > [filename].iv to redirect the output to [filename].iv format

Cleanup

• You can type make rm to remove executable the CG_hw3 and run again
