Professor Barnes will not grant extra credit, time, debugging time, or anything else should you find a bug in the code; I may say, "Thanks for pointing that out!".

• Draw a cube
  • [ cube.cpp ] demonstrates OpenGL and OOP class, basic OpenGL program structure.
    Cube * cube; // dynamic object reference example.
    cube -> draw();
  • [ staticCube.cpp ]
    Cube cube; // static object reference example.
    cube.draw();
• Most of the examples that follow also require file openGL.h to be included. These examples allow you to add all include files to the project as well as include them.
  Examples that are in subdirectories have openGL.h in the directory.
  Single file examples use [ openGL.h ]
• Animation of 3 torii
  • Single viewport [ animate directory ] : torus.cpp and animate.cpp demonstrate using include for class definition file, glutTimerFunc, glutIdleFunc, estimating fps. updated 9/14/2012
  • Three viewports [ animateViewport directory ] : animateViewport.cpp and torus.cpp files (uses openGL.h) updated 9/21/2012
  • Three viewports and a Transformation Matri [ animateViewportMatrix directory ] : animateViewportMatrix.cpp, torus.cpp and constants3D.h
• Using matrices to view and place many cube objects in a scene.
  These examples have been updated to use #ifndef so that all files can be added to the project. Also uses include openGL.h
  • Array based approach with dynamic objects: [ manyCubes directory ] : cube.cpp and manyCubes.cpp files. updated 9/15/2012
  • Array based approach with static objects: [ staticManyCubes directory ] updated 9/15/2012
  • Standard Template Library (STL) vector based approach: [ vectorManyCubes directory ] : cube.cpp and vectorManyCubes.cpp files updated 9/15/2012
• C++ and GLUT spot light demo [ spotLight.cpp ] : sphere tesselation, shading, menu, and spot light. Modified from example in Ch 5 pp 212 - 222 SuperBible 4th edition. updated 9/14/2012
• Using matrices in OpenGL
  • Hierarchical Modelling with pushMatrix / popMatrix, E. Angel's figuretree.c
  • Getting values from OpenGL matrices matrixInfo.cpp update 9/14/2012
  • FreeMat function library:
• Shadows in OpenGL with projection shadowShape.cpp.
• Picking and selection buffer example pickExample.cpp Uses both ortho and pespective projection for selection. Uses wireframe to visually show the selected sphere.
• Example that loads and display a *.raw texture rawTexture directory .
  You also need to save the texture "therapist.raw". (*.raw and *.tga textures will not open in most browsers).
• Modified TGA image example from SuperBible V5 stonePyramid directory example. Example stonePyramid illustrates loss of geometry color when textures are not enabled/disabled (press 't' to see effect).
• Blending example waterBlend directory contains program and raw texture files.
• Using AC3D modeler triangle files in openGL. triangleLoader.cpp is a program to convert *.tri file to openGL draw method.
  Usage in a terminal / command window:
  triangleLoader < aModelFileName.tri
  Output file is named "drawTriModel.cpp"
  viewModel.cpp is a program that displays the openGL draw method created by triangleLoader.
• GLSL shader demos
  • GLSLexample,
    You need to copy all 3 files: GLSLexample.cpp, vertexShader.glsl, and fragmentShader.glsl into a project. You may also need to install GLee; see notes in header comment.
  • GLSLattribute, updated 11/20/2012 fixes light in shader
    You need to copy all 3 files: GLSLattribute.cpp, vertexAttribute.glsl, and fragmentAttribute.glsl into a project.
    Shader and no shader rendering / frame. updated 11/27 to change light positions
• OpenGL NURBS surface demo nurbsSurface.c.
  Key 'c' displays control points, 'w' toggles wireframe or fill, 'u' and 'v' cycles through 3 sets of u and v knot values, and 's' cycles through 3 sets of sampling tolerances.
