What is (makes for) 3D computer graphics? [the answer is NOT 'stereo'!]
What is computer graphics 'rendering' ?
In CG, what is a 'model'? Also, mention another area/field where the word 'model' is used.
In CG rendering (or digital images in general), what is 'resolution'? Also, what is another area/field where 'resolution' is used?
What is stored in a 'framebuffer'?
What do 'LEE' and 'DDA' stand for, in the context of scan conversion?
Mention any two hidden-surface algorithms.
What are a couple of properties related to translation through 3D space?
What are the five distinct co-ordinate 'spaces' used in the classic rendering pipeline?
What are a couple of differences between local and global illumination?
Name the three components (parts) that make up the classic lighting equation.
When it comes to parameter interpolation (eg. of uv texture coords) during scan conversion-based rendering, what does "perspective correction" mean?
Explain BRIEFLY how texture mapping works (ie. how an image ("texture map") gets on to a 3D rendered surface).
How does bump mapping differ from displacement mapping? Why even have these two different techniques (why not always just use one of them)?
In addition to being used for texturing, maps have several other uses as well - name two.
State the Nyquist sampling theorem in simple words, along with a (simple) diagram.
Mention four shadow-generation techniques.
How does the NPR technique of toon-shading work? Explain, using a simple figure.
What is a 'lightfield'? Name one practical (commercial) device that can record (capture) it.
Name any four commercially available renderers.
Look at the flattened cube on the left, in the figure below. Which of the cubes on the right (a or b or c or d) could have produced the flattened version?
