|Student Learning Outcomes -|
- A successful student will be able to write code using a specific 3D API such as OpenGL that generates 3-D images and motion. Aspects of the API that will be mastered include setting up the configuration space, specifying the projection, camera positions and lighting parameters, and attaching material properties to the scene members.
- A successful student will apply the mathematical tools of matrices, normal vectors and linear transformations to the design of graphics programs.
|Description - |
|Introduction to 3-D graphics programming using OpenGL, intended for anyone interested in gaining 3-D expertise for games, scientific visualization, desktop and mobile apps. Coding topics include a systematic study of the OpenGL API in conjunction with any of these programming languages: Java, C++, C# or Objective C (student's choice). Concept topics include viewports, graphics primitives, 3-D motion matrices, normal vectors, shaders, fragment and pixel buffers, light simulation, polygons, virtual cameras, image pipelines, texture mapping and alpha blending.|

- Install and access the OpenGL API in an integrated development environment (IDE).
- Create an OpenGL graphics context within an operating system's native user interface (UI).
- Describe distinct roles of the graphics initialization and drawing operations.
- Define the meaning of glBegin()/glEnd() and how they are used to define points, lines and polygons.
- Write programs that use normal vectors and orthographic projections to simulate naturally lit 3-D scenes.
- Use frame buffers to effect real-time 3-D animation.
- Incorporate vertex arrays into programs.
- Define buffer objects and give examples of their use.
- Explain the difference between viewing, modeling and motion transformations.
- Produce programs that use matrix stacks to control complex, hierarchical motion.
- Incorporate color and alpha blending into programs to generate transparency effects.
- Control scene lighting through camera position, material parameters, spotlights, and ambient parameters.
- Use OOP and class inheritance to design flexible objects, materials, lighting and animation structures.
- Write programs that incorporate texture mapping to simulate complex surfaces.
- Describe the OpenGL shading language and shaders.
- Download and install 3rd party font libraries for OpenGL.
|Special Facilities and/or Equipment - |
- access to a computer laboratory with language compilers, and OpenGL API plugins.
- a website or course management system with an assignment posting component (through which all lab assignments are to be submitted) and a forum component (where students can discuss course material and receive help from the instructor). This applies to all sections, including on-campus (i.e., face-to-face) offerings.
- When taught via Foothill Global Access on the Internet, the college will provide a fully functional and maintained course management system through which the instructor and students can interact.
- When taught via Foothill Global Access on the Internet, students must have currently existing e-mail accounts and ongoing access to computers with internet capabilities.

|Lab Content - |
- Configuring an OpenGL Development Platform

- Write and debug a a modular 2-D shape program that lives within your platform's native UI using a module init() and draw() paradigm.

- Write a program that demonstrates at least six of the graphics primitives managed by glBegin() and glEnd().
- Make the program interactive, using a simple menu with drop-downs, sliders, buttons, etc.
- Creating a Simple 3-D Scene

- Controlling Camera Position and Complex Object Motion
- Create classes that reflect hierarchical objects with multiple joints and appendages.
- Use the modelview stack to control the various parts of the object, independently, without losing the integrity of the object as a whole.
- Let the user control motion and also demonstrate various speeds.
- Separate camera and object motion in your program, so that the user can control each one, separately.
- Controlling Color and Lighting
- Use OOP to create material classes and assign materials to the players in your scene.
- Assign different characteristics to your scene's lights and ambient illumination.
- Let the user control the lighting characteristics while the objects are in motion.
- Incorporating Texture Mapping
- Load two or more textures into memory, and assign them to some of your objects.
- Display the scene with animation to view the textures at all angles as they are rotated.
- Incorporate transparency and alpha blending.
