The Razor Code Structure

The structure of the code is -

• icollab
  • collada
    • COLLAborative Design Activity - For establishing an interchange file format for interactive 3D applications.
    • Developed by Sony during development of PS3.
    • Use for exchanging info among various graphic apps, that might otherwise store their assets in incompaitable format.
  • common
    • Contains the razor ray tracing code - the common files.
    • Other dirs include -
    • arena
    • bmp - Code for reading/writing bmp data.
    • catchall
    • filter -> Code for filtered image rescaling
    • geom -> Implementation of the geometry system. Contains the engines for loop and planar subdivision and the Catmull-Clark geometry system.
    • glut -> The opengl toolkit for windows.
    • hilbert
    • jpg, png, tiff -> libs for supporting these filetypes
    • logging
    • params -> The parameter manager code. Used for get/set/existance of parameters.
    • simpmath -> Simple math manipulations required for ray tracing.
    • sseaux -> Looks like deprecated code for modifying SSE variables.
    • Vtune -> Contains code for compiling with special hooks in vtune.
    • xml -> Contains the libxml files.
    • zlib - The zlib compression library.
• docs -> Misc and random docs regarding licensing, submitted papers, memory usage, spec, wiki-backup etc.
• misc
• razor
  • Contains the main razor ray tracing code. This includes the kdtree manipulations, segment, shading, ray tracing and lighting.
• RazorStaticLib
• scenes
  • Scenes used to test the ray tracing. This dir is what makes the codebase so huge in size.
• SCons
  • SCons is make equivalent, based on python. Files for Scons maintainence.
• scripts
  • Perl scripts to run razor with different settings.
• tools
• build.bat --> Builds the VC solution for Razor.
• icollab.sln --> The V solution file used to launch the build
