Alpha trace

A raytracer written in C++

I am following the excellent tutorial and introduction to computer graphics by Scratchapixel, here.

Directory structure

• build: This folder contains all build files, and is removed on a clean. See building section for build instructions.
• doc: Any notes and docs are here.
• src: This includes all the source files which belong to the project
• include: Any headers included within the project
• spike: Any small testcases, ideas or implementations live here
• thirdparty: All third party headers, libs etc live here.
• cfg: Custom config for the project.
• test: All test code files.

Building

Requirements

• CMake (version 2.6 or greater)
• make
• C++11 compliant compiler set up with appropriate standard headers and libraries(tested with g++-4.8 & clang++-3.6)
• Google benchmark for compiling benchmarks

Steps

From the project root... you know the deal.

1. cd ./build
2. cmake ..
3. make

All files resulting from the build are placed in build directory.

Dev environment

The ycm_extra_conf.py is placed in the cfg folder. To automatically source this file when in the project directory, add the following to your vimrc

if filereadable("../cfg/ycm_extra_conf.py")
    let g:ycm_global_ycm_extra_conf = '../cfg/ycm_extra_conf.py'
else
    let g:ycm_global_ycm_extra_conf = '~/.vim/.ycm_extra_conf.py'
endif

This has one limitation, vim needs to be started from a directory one level deeper than the cfg directory, ie. any subdirectory of the project root, for proper YCM config.
