Homework 5 Overview

In this project you shall implement some of the image manipulation operations we discussed in class. The following [ Visual Studio solution ] contains a working program that reads in and displays a bmp file usain_bolt.bmp. Your task will be to program various GLSL fragment shaders that implement various operations that we learned in class and control the effects interactively using keystrokes. You will implement some of the image-manipulation operations previously discussed in class. You will be loading generating/loading and unloading 2 textures (a BMP image and a Mandelbrot Fractal).

Preparation

• Read in/Display Usain Bolt BMP image: To start off, download the Visual Studio Solution, compile it and run it. It's the same program you used in homework 4. To read in the usain_bolt.bmp file, the program uses use the [ libbmpread library ] which is a tiny, fast bitmap (.bmp) image file loader. Specifically, libbmpread is implemented as two files bmpread.c and bmpread.h which have been included in the Visual Studio starter code. bmp file loading functions and data structures are then used in the starter program to load the bmp file.
  
  
• Set up Mandelbrot example: Section 9.8.5 of your text describes a setup to render the Mandelbrot set. Example2.cpp and its associated shaders on the book website implement a working mandelbrot set program: [ Here ]. Get the program and set it up. Write a program that runs this Mandelbrot set and save it as a second texture.
  
  
• Add interesting colors to the Mandelbrot set: Try to change the default colors to an interesting Mandelbrot pattern. This exercise is useful in learning how to control the colors the procedural renderer uses.

Submitted Program Behavior

Your program behavior should be as follows.

User hits:

• For keys 'O, L, N, D, E, T, W, P and S' below you will load and modify the usain_bolt.bmp file in the starter image loader code.
  • Key 'O': Display original picture (usain_bolt.bmp)
  • Key 'L': Display picture with Luminance effect (gray scale)
  • Key 'N': Display image negative
  • Key 'D': Display image with edge detection effect
  • Key 'E': Display image with embossing effect
  • Key 'T': Display image with Toon rendering
  • Key 'W': Display image with Twirl Transformation
  • Key 'P': Display image with Ripple Transformation
  • Key 'S': Display image with Spherical Transformation
• Key 'R': Load the Mandelbrot texture and display it

Submitting Your Work

Make sure to double-check that everything works before submitting. Submit all your executable and source files. Put all your work files (Visual Studio solution, OpenGL program, shaders, executable and input files into a folder and zip it. Essentially, after your project is complete, just zip the project directory created by Visual Studio. Submit your zip file using InstructAssist at [ https://ia.wpi.edu/cs543/ ] . Do not email me your program or submit it via dropbox. To make your submission smaller, delete the \ipch folder in the visual studio. On recompilation, Visual Studio will regenerate this folder without problems.

Create documentation for your program and submit it along with the project inside the zip file. Your documentation can be either a pure ASCII text or Microsoft Word file. The documentation does not have to be long. Briefly describe the structure of your program, what each file turned in contains. Explain briefly what each module does and tie in your filenames. Most importantly, give clear instructions on how to compile and run your program. MAKE SURE IT RUNS IN THE ZOOLAB before submission. Name your zip file according to the convention FirstName_lastName_hw5.zip
