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.
The student will be able to:
A. Install and access the OpenGL API in an integrated development environment (IDE).
B. Create an OpenGL graphics context within an operating system's native user interface (UI).
C. Describe distinct roles of the graphics initialization and drawing operations.
D. Define the meaning of glBegin()/glEnd() and how they are used to define points, lines and polygons.
E. Write programs that use normal vectors and orthographic projections to simulate naturally lit 3-D scenes.
F. Use frame buffers to effect real-time 3-D animation.
G. Incorporate vertex arrays into programs.
H. Define buffer objects and give examples of their use.
I. Explain the difference between viewing, modeling and motion transformations.
J. Produce programs that use matrix stacks to control complex, hierarchical motion.
K. Incorporate color and alpha blending into programs to generate transparency effects.
L. Control scene lighting through camera position, material parameters, spotlights, and ambient parameters.
M. Use OOP and class inheritance to design flexible objects, materials, lighting and animation structures.
N. Write programs that incorporate texture mapping to simulate complex surfaces.
O. Describe the OpenGL shading language and shaders.
