What is Computer Graphics?
Computer graphics is one of the fundamental aspects of any computing system. Its primary role is to render the digital content (0’s and 1’s) in a human-comprehensible form on the computer screen. The rendering follows a series of stages, collectively known as the graphics pipeline. In this course, we will introduce the pipeline and its stages. The topics covered include various object representation techniques followed by the pipeline stages of modeling transformation, 3D to 2D viewing transformation, clipping and hidden surface removal and scan conversion (rendering). We shall follow the stages of the 3D graphics pipeline. In order to complete the coverage, we shall also briefly introduce the present day graphics hardware (I/O devices, GPU) and the widely popular openGL graphics library.
- Week 1: Introduction – historical evolution, issues and challenges, graphics pipeline, hardware and software basics
- Week 2: Object representation – boundary representation, splines, space partitioning
- Week 3: Modeling transformations – matrix representation, homogeneous coordinate system, composition, 3D transformations
- Week 4: Illumination and shading – background, simple lighting model, shading models, intensity representation, color models, texture synthesis
- Week 5: 3D viewing – viewing pipeline, view coordinate system, viewing transformation, projection, window-viewport transformation
- Week 6: Clipping and hidden surface removal – clipping in 2D. 3D clipping algorithms, hidden surface removal
- Week 7: Rendering – scan conversion of line, circle, fill-area and characters, anti-aliasing
- Week 8: Graphics hardware and software – generic architecture, I/O, GPU, Shader programming, graphics software (openGL)
The course is free to enroll and learn from. But if you want a certificate, you have to register and write the proctored exam conducted by us in person at any of the designated exam centres.
The exam is optional for a fee of Rs 1000/- (Rupees one thousand only).
Date and Time of Exams: 25 September 2022 Morning session 9am to 12 noon; Afternoon Session 2pm to 5pm.
Registration url: Announcements will be made when the registration form is open for registrations.
The online registration form has to be filled and the certification exam fee needs to be paid. More details will be made available when the exam registration form is published. If there are any changes, it will be mentioned then.
Please check the form for more details on the cities where the exams will be held, the conditions you agree to when you fill the form etc.
CRITERIA TO GET A CERTIFICATE
Average assignment score = 25% of average of best 6 assignments out of the total 8 assignments given in the course.
Exam score = 75% of the proctored certification exam score out of 100
Final score = Average assignment score + Exam score
YOU WILL BE ELIGIBLE FOR A CERTIFICATE ONLY IF AVERAGE ASSIGNMENT SCORE >=10/25 AND EXAM SCORE >= 30/75. If one of the 2 criteria is not met, you will not get the certificate even if the Final score >= 40/100.
