Q3:

According to Ed Leonard, the CTO at DreamWorks “Shrek 3 consumed 20 million CPU render hours with 3000+ server CPUs, with 24TB file size”.

Suppose the personal computer CPU advanced so much so that we accomplished that goal by fabricating 3000-core Processor Motherboard. Would this new multicore machine perform as well as the parallel processing employed by DreamWorks?

Give 2 justifications to support your answer?

Q4: Explain (in your own words) how does JAGGIES happens in text and what is the technique used to mitigate the JAGGIES effect? Mention an application that applies that technique.

Answer 1

3.) Justifications:

A 3000 core processor on CPU board are going to be performing well than a 3000 seprate servers conencted together. this will justified with logical points. one powerful processor are going to be always faster than seperate ones thanks to reduced coplexity and straightforward maintaining. one processor can easily schedule and queue the processes accordingly itself without transfering or expecting other machines to reply .

In case of multiple severs, an administrating system need to assign the task to a free server. this may make some delay of respond time. When it's one processor, no such respond time delay is predicted . The work are going to be directly assigned to the only machine and it'll accept to its multiple cores.

It will also reduce the amount of devices and there by reduce the value of implementation. one machine will consume only less power and can be very easy to take care of . just in case of any updation or failure tracking, we've to require care of only a machine here.

4.) Jaggies may be a term mentioned a "staircase" effect which simply a series of flights of steps and a structure connecting separate levels.Jaggies are observable when a picture is rendered on a bitmap display or we will say that once we enlarge or zoom-up a picture or text.Jaggies occurs in text because there aren't enough pixels left within the text on the screen to point out it realistic.

Following are the techniques to mitigate jaggies from text or an image:

1. Anti-aliasing:

It is a way utilized in special effects to get rid of the jagged edges or "jaggies" in a picture or a text.Antialiasing smoothes out jagged lines by surrounding the jaggies with shaded pixels.

2. Smoothing:

Some printers can reduce jaggies with a way referred to as smoothing.Here the effect occurs when a picture scan conversion is completed with sampling at a coffee frequency.

3. Using high-resolution Display:

This displays objects at a high resolution.Usin high resolution, the jaggies become so small that they become unseen to human eye.So, the jagged edges get blurred out and edges appear smooth.

Applications where these techniques are applied:

1. Retina displays in apple devices(Using high-resolution Display)

2. OLED Displays(Using high-resolution Display)

3. Anti-aliasing technique is employed to get rid of jaggies from area boundaries. Applied to scanline algorithms to smoothen out area boundaries.

4. SSAA(Supersampling Antialiasing) technique
