Experiments:
- Play with (i) projection.exe,
lightposition.exe, and shapes.exe from Nate Robin’s tutor
repository to learn about the synthetic camera model and the
basics of OpenGL primitives for drawing 2D geometric objects, and (ii) a sample program to generate a static 3D scene
Static3DScene.zip.
- Check whether you can successfully compile the
following sample programs: simple.cpp and earth.cpp.
Reading #1:
Browse through (i) Chapter1 of OpenGL
programming guide (the red book), (ii) sections 2, 3, and 7.1 of GLUT 3.0
specification, and (iii)
try to understand the sample programs: simple.cpp and earth.cpp.
Lab#1: A Simple Static Scene Viewed from a Static Camera with Orthographic Projection due Wednesday, Feb 6.

on event handlers and the related glut functions
Reading #2: Read the following parts of GLUT 3.0 specification: Sections 2~3 on initialization and the event loop, Sections 7.1~7.6 on registration of basic callback functions, Sections 4.5~4.6 on posting a redisplay event and the swapping of double buffer. Report Due: Wednesday, Feb 13.

Week 5: More
on 3D Model Transformations. Progress report due Wednesday, March 5.
Reading #5: (i) Play
with this sample program about Sierpinski
gasket fractal (see this link)
and watch the console application to see the difference between the windows
coordinates you get from the mouse events and the world coordinates of objects
in the world. (ii) Review Chapter 3 of the
OpenGL programming guide on state management and geometric objects. (iii) Read the blue book
regarding the use of GLUquadricObj,
gluNewQuadric, gluQuadricDrawStyle, gluCylinder, gluSphere, gluDisk, gluPartialDisk
and review the sample code here to see the use
of several of those types of geometric objects available in GLU and GLUT. due Wednesday, March 5.
Lab#4A:
Composing Static
Scenes Using Basic Geometric Objects and Affine Transformations. Due: Wednesday, March 5.
Lab#4B: Due: Wednesday, March 12.
- Model the Biola bell tower in 3D, including the three pillars, the bells, the ground supports.
- Allow the user to view it either from a fixed camera location or through a camera automatically circling around the bell tower.
Weeks 6~7:
More on the implementation of advanced GUI features using GLUT; Test #1. Progress report due Wednesday, March 12.
Reading #6: (i)
Download and play with compact example
(sample code and an executable included) demonstrating the implementation of an
advanced glut mouse motion function to translate dragging events into actions
along X, Y, Z axes. Examine the code to understand the underlying
implementation. (ii) Download and
play with this
example program on the setup of a menu system using GLUT. (iii) Read
the following parts of GLUT 3.0
specification: section 6 on glutCreateMenu,
glutAddMenuEntry, glutAttachMenu, section 7.5 on glutMouseFunc, and 9.1
on glutGet. Read the related
sections of Online
OpenGL 1.1 reference guide on glGetDoublev,
glGetIntegerv, and gluProject. Read the usage
of acos and fabs in
<cmath>
of C++. (iv) Download and play with the code and the executable of the sample 3D
scene modeler in this zip file. Create a simple scene using the modeler and
save the scene as a SNAPS?_Scene?.cpp file. Examine and compile this resulting
.cpp file to see how it can render the snapshot.
Lab#4C: Due: Wednesday, March 19.
Enhance your Biola bell tower graphics program in Lab4B to
- show the X, Y, Z axes in addition to the bell tower,
- add a menu and implement the related menu event handlers such that the user can choose one of two operation modes to either (i) move the location of the eyes (i.e. the camera) or (ii) change the center at which the eyes (i.e. the camera) look at by dragging the mouse along X, Y, Z axes, and
- add a mouse motion event handler and other related functions to realize both operational modes.
Test #1 (in-class open-book):
· See this zipped Windows executable and a screenshot (Jennifer Russell) for problem #5 on a bus moving around a circle.
Weeks 8~9:
Introduction to Lighting and material;
Spring break. Progress report due Wednesday,
April 9.
Lab#5: Based on the graphics program you have for Lab#4C or 4B, enhance the program with the following additional features: (i) Properly specify the material properties of your objects, (ii) specify at least one light source and enable lighting in OpenGL, (ii) enable depth buffer testing and properly use the related OpenGL commands to have hidden surface removal. Due: Wednesday, April 9.
Weeks 10-11:
Intro to texture mapping; Mission Conference
·
Chapter 9 on texture
mapping from the Online OpenGL 1.1 programming guide and
understand these key OpenGL texture mapping
commands.
·
Play with texture.exe from
Nate Robin’s tutor
repository to get a sense of the issue of
texture mapping.
·
Download this zipCube.zip and
crefully examine how texture mapping of a family picture onto a cube is done through the CreateTexture function in tga.h and
tag.cpp to load a tga picture and map it onto surfaces.
·
Also see texture
mapping for (i):
mapping multiple images to surfaces in a static scene, (ii): mapping a
checkerboard image onto a glutTeapot object, and
(iii): mapping
two checkerboard images onto two rectangles.
Lab#6: Due: Wednesday, Wednesday, April 16.
