Added Features

• Texture mapping of noise
• opaque texture mapping
• transparent texture mapping
• bump mapping

• new classes
• Planet
• Ocean
• Clouds

Comments

• The image
• the scene consists of four objects
• The ocean is a rectangle with bump mapping produced from noise
• The clouds are a plane with transparency mapping produced from noise
• The planets are spheres that are texture mapped using noise

• The code
• New classes Planet, Ocean, and Clouds
• The frequency of all maps can be user defined

Files

(set tab stop to 4 in order to view these files correctly)

• Noise.cpp This file contains Robert Skinner's noise function for a single variable as well as a vector valued noise function.
• Ray.exe The executable file.
• RayMath.h RayMath.cpp These files contain the Vector and Matrix classes
• RayGraphics.h RayGraphics.cpp These files contain the classes Light, Color, and Eye
• RayObjects.h RayObjects.cpp These files contain the all geometric objects used in Ray
• setup.h Setup.cpp These file contains various constants to be used in Ray. Some commonly used function prototypes are used in this file. Some externed variables are also included so all files can access them.
• Beach.cpp This file creates the lights and all objects along with their parameters.
• TraceRay.cpp contains code to determine the coloring of a specified pixel.
• rayView.cpp This is the main function which calls all other functions. The windows code is also within this file. The windows code has been seperated from the C++ Ray code as much as possible.
• miscellaneous windows files. Contact the arthor if you need these files in order to compile the project (Some of these files are large).
