How to master this article on computer graphics?

Question

Algorithms

I just can’t master this series of articles, and especially fulfill its condition - write the code myself, and use the working version as a comparison. But it’s hard for me to write my own code, I just don’t have any ideas how to do it all and where to start writing a certain function, especially when I also need to work with ready-made models. I attribute this to a lack of both experience and knowledge, because reading and trying to understand all this is difficult, but interesting, but I don’t quite understand how to write it myself. Perhaps for this series of articles you need something else besides basic knowledge of the language + basic knowledge of algorithms?

Answer 1

other than basic knowledge of the language + basic knowledge of algorithms?

Do you have it? I doubt if you can't handle it.
I've never worked with this, but ran diagonally and everything is quite simple. What exactly is your problem? Create a "framework" (a program where you will write functions), it is enough to draw an output in the graphics window.
And go ahead.

Answer 2

Perhaps for this series of articles you need something else besides basic knowledge of the language + basic knowledge of algorithms?

- Yes, everything is elementary. It is necessary to get an education in the field of IT, study the algorithms for working with video images, get a hand (gain experience) in writing at least some programs - and wow, such articles will be understood at once.
And you thought programming was almost like plumbing? To understand where the four classes of education flow from? Came in with a wrench, fixed a leak, got a lot of money?

Answer 3

Instead of this cycle on computer graphics, try to deal with something simpler.
For example, read and solve a book on algorithms, solve problems on leetcode, get a hand in solving simpler things.
And you can also read SICP and a good book on pluses. Well, or instead of a book on pluses, take a course on the stepik "White Belt in C ++" and others from the series.
Next, it is worth delving into the actual theory of computer graphics. Part will be just in this series of articles.
PS: Learn to use Git and Github/Bitbucket. It will be easier to show large code and ask questions.
