Objectives

BACKGROUND Computer graphics has been stated and is today a very important component in the whole human-computer interaction ambience. However, its applicability goes far beyond, having nowadays a prominent position in major industries such as the cinema and electronic games. Also in technology and science it plays an irreplaceable role allowing the visualization of phenomena, often linked to simulation and virtual reality techniques. In this course, the approach to computer graphics is made under a Top-Down philosophy, starting with the subjects most related to 3D (image synthesis, modelling) and ending with a visit to several most basic algorithms in 2D. The 3D components of the programme are accompanied, in practical lessons, with exercises based on the usual technologies, like OpenGL and WebGL.

SPECIFIC AIMS -Transmit knowledge of concepts, techniques, algorithms, computer graphics technologies and architectures. -Strengthen the theoretical knowledge with practical application, through the implementation, testing and evaluation of algorithms discussed in theory.

PERCENTAGE DISTRIBUTION
-Scientific Component: 50%
-Technological Component: 50%

Eligibility for exams

Not exceed the absence limit and obtain a minimum of 40% in the distributed evaluation classification.

Calculation formula of final grade

Legend:
FG: Final Grade
ExEv: Exam grade
DisEv: Distributed Evaluation

FG = 60% ExEv + 40% DisEv

DisEv = 50% Mini-tests + 50% Small Project

To pass, the student must have a minimum of 40% in any of the two evaluation components: distributed evaluation and final exam. NOTE: Minitests are closed book; Final exam is open book.

Examinations or Special Assignments

Minitests will occur (hours defined for the theory classes) in the following dates:

   - 2016-03-31
   - 2016-05-19

Special assessment (TE, DA, ...)

Students with worker statute or equivalent must, preferably, make the minitests correspondent to the distributed evaluation, but the small project is mandatoryeven for them. They must agree, with the teachers, dates to show the evolution of the practical works.

Final grade may then be calculated as in Classification Improvement.

Classification improvement

For classification improvement purposes, the distributed evaluation corresponds only to the 20% of the small project (exam weights 80%); mini-tests may not be taken into consideration.

Observations

About the teaching language: Portuguese is the "regular" language used, but English can be used if foreign students participate in classes. Moodle is the e-learning tool used in this course.
