问题 I am about to start a project for university to build a procedural city for a pre existing project. I was wondering if any of you have had any experience coding L-Systems before and know a good place for me to start out. I have done a bit of work before using procedural methods and Perlin Noise and fBm so I get the premise of what an L-System is in the fractal sense. I am more looking for a place where maybe can push me in the direction of coding the L-System. Any help or technical documents

问题 Yeah, I'm struggling with that. I cannot distinguish among them because every explanation I read is so unclear and philosophical enough. Can someone clear up these definitions for me ? Thanks guys. These definitions apply as much to procedural-programming as oop ? Thanks. 回答1: Function is a combination of instructions coupled together to achieve some result. It may take arguments and return result. If a function doesn't return a result it is usually called a procedure. Examples: function

问题 I'm really having a hard time understanding the difference between procedural and functional programming paradigms. Here are the first two paragraphs from the Wikipedia entry on functional programming : In computer science, functional programming is a programming paradigm that treats computation as the evaluation of mathematical functions and avoids state and mutable data. It emphasizes the application of functions, in contrast to the imperative programming style, which emphasizes changes in

问题 I was asked a question in an interview: if encapsulation is possible without OOP, e.g. in a procedural language? 回答1: Bob Martin has stated that encapsulation is not only possible without OOP, it was better before OOP came along. Here is an excerpt from a talk he gave in 2014 at Yale School of Management. We had perfect encapsulation. In C, all you had to do was forward declare your functions and your data structures. You didn't have to implement them. You would forward declare them in a

问题 Suppose I've decided to write a large application in C, or any other procedural programming language. It has functions with call-dependencies that look like this: A | +-------------+ | | B1 B2 | | +------+ +------+ | | | | C11 C12 C21 C22 Obviously, unit-testing the leaves functions, C11, C12, C21, and C22 is very easy: Setup the inputs, invoke the functions, assert the outputs. But what is the proper strategy to enable good unit-testing for B1, B2 and A? Would Dependency Injection suggest

问题 I am new to both android and java. I am developing a simple app which contain country , state and city which are selected by spinner. Now consider while am selecting the country(India) then i need to get only states of india. And then while selecting any state(Andhra pradesh) then the cities of A.P should be shown in the next spinner. Can any one suggest me with some sample code. thanks in advance 回答1: you can add this logic(for two spinners) to your code: public void onCreate() { ....

问题 I have started reading "Think Like A Programmer" by V Anton Spraul. Here is the question. The train technique mentioned in the book works fine for the example sighted in it. I was attempting to write the train approach method to solve the sliding tiles problem. Assuming that I am working on subset of the complete problem, for the below set of tiles (as given as example in the book), the approach mentioned works fine. 6 8 . 5 4 7 We move anti-clock wise until we get 4,5,6 in order in top row

问题 I am using the diamond-square algorithm to generate random terrain. It works fine except I get these large cone shapes either sticking out of or into the terrain. The problem seems to be that every now and then a point gets set either way too high or way too low. Here is a picture of the problem And it can be better seen when I set the smoothness really high And here is my code - private void CreateHeights() { if (cbUseLand.Checked == false) return; int Size = Convert.ToInt32(System.Math.Pow
