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.

Eligibility for exams

Class attendance requirements are subject to the regulations in force and the student must, in particular:

• Not exceed the limit of absences at recitations.

Additionaly, the student must comply with the following set of points, without which cannot be approved due to the lack of component:

• Present the practical works and projects announced;


• Carry out the planned minitests;


• Obtain a minimum of 40% in the distributed evaluation.

Working students and equivalent students are not subject to the class attendance requirements or the obligation to take mini-tests.

Calculation formula of final grade

Legend:
    FG: Final Grade
    ExGr: Exam grade
    DisGr: Distributed Evaluation Grade

FG = 50% ExGr + 50% DisGr

DisGr = 30% MiniTests + 70% Project

NOTES:

• The two mini-tests have equal weight in obtaining the "MiniTests" grade;
• To pass, a minimum of 40% is required in each one of the two assessment components (distributed evaluation and final exam).
• Access to exams, in the ordinary or supplementary call, is not allowed to students who have not fulfilled class attendance requirements;
• The supplementary call aims to take the final exam and maintain the marks obtained in the mini-tests and the project.
• The mini-tests and the final exam are "closed book" style.

Examinations or Special Assignments

Access to evaluation in specific periods (students with legally applicable statutes, completion of the cycle of studies...) is conditioned to the fulfilment of previous class attendance requirements concerning the absence limit.

The special assessment period consists of an exam and a project, and the respective grade is obtained by:
    FG = 65% ExGr + 35% Project

The "Project" parcel is the grade obtained previously; if it does not exist or is less than 40%, it is the grade obtained in a project designed for this purpose and whose operation must be agreed in advance with the professor.

Special assessment (TE, DA, ...)

Students with the student worker statute or equivalent should preferably take the mini-tests included in the distributed assessment. The practical works and projects listed are compulsory, so these students must take the initiative to agree with the teacher on dates for their follow-up, as well as make the respective submissions on the normal dates.

The final grade will be calculated as in "Classification improvement", if the student has not taken the mini-tests. If the student has taken the mini-tests, they will be awarded the highest mark obtained, using the normal formula (with mini-tests) or using the improvement formula (without mini-tests).

Classification improvement

When calculating the grade in a situation of Classification improvement, the mini-tests grade may be waived if the result is favourable to the student, according to:

   FG = 65% ExGr + 35% Project

Observations

Although the "regular" language of classes is Portuguese, English may be chosen if foreign students attend the course.

Support material for the course and assessment results are published on FEUP's Moodle.
