<数百个 HTML5 例子学习 HT 图形组件 – 拓扑图篇>一文让读者了解了 HT的 2D 拓扑图组件使用,本文将对 HT 的 3D 功能做个综合性的介绍,以便初学者可快速上手使用 HT 构建例如电信网管 3D 机房应用.水务燃气 SCADA 监控应用及智能楼宇等应用场景. HT for Web 的 3D 是完全基于 WebGL 技术实现的渲染引擎,但开发者几乎不需要了解 3D 图形数学或 Shader 渲染的底层技术,只需要掌握基本的 3D 坐标系和相机 Camera 的概念,剩下需要掌…
HT 是啥:Everything you need to create cutting-edge 2D and 3D visualization. 这口号是当年心目中的产品方向,接着就朝这个方向慢慢打磨,如今 HT 算是达到了这样的效果,谈不上用尽洪荒之力,但我们对产品结果很满意,特别是 HT 的用户手册,将例子和文档无缝融合一体,小小 10 来兆开发包居然包含了四十五份手册,数百个活生生的 HTML5 例子,还没体验过的同学可以点击 http://www.hightopo.com/guide/…
经典的Fibonacci数的问题 主要想展示一下迭代与递归,以及尾递归的三种写法,以及他们各自的时间性能. public class Fibonacci { /*迭代*/ public static int process_loop(int n) { if (n == 0 || n == 1) { return 1; } int a = 1, b = 1; int i = 1; while (i < n) { i++; int t = b; b = a + t; a = t; } return…
Given four lists A, B, C, D of integer values, compute how many tuples (i, j, k, l) there are such that A[i] + B[j] + C[k] + D[l] is zero. To make problem a bit easier, all A, B, C, D have same length of N where 0 ≤ N ≤ 500. All integers are in the r…
Given a non-empty array of integers, return the third maximum number in this array. If it does not exist, return the maximum number. The time complexity must be in O(n). Example 1: Input: [3, 2, 1] Output: 1 Explanation: The third maximum is 1. Examp…
Calculate the sum of two integers a and b, but you are not allowed to use the operator + and -. Example: Given a = 1 and b = 2, return 3. Credits:Special thanks to @fujiaozhu for adding this problem and creating all test cases. 这道题是CareerCup上的一道原题,难道…
Given an integer (signed 32 bits), write a function to check whether it is a power of 4. Example: Given num = 16, return true. Given num = 5, return false. Follow up: Could you solve it without loops/recursion? Credits:Special thanks to @yukuairoy fo…
Given an integer, write a function to determine if it is a power of three. Follow up:Could you do it without using any loop / recursion? Credits:Special thanks to @dietpepsi for adding this problem and creating all test cases. 这道题让我们判断一个数是不是3的次方数,在Le…
Write a program to find the nth super ugly number. Super ugly numbers are positive numbers whose all prime factors are in the given prime list primes of sizek. For example, [1, 2, 4, 7, 8, 13, 14, 16, 19, 26, 28, 32] is the sequence of the first 12 s…
Write a program to find the n-th ugly number. Ugly numbers are positive numbers whose prime factors only include 2, 3, 5. For example, 1, 2, 3, 4, 5, 6, 8, 9, 10, 12 is the sequence of the first 10 ugly numbers. Note that 1 is typically treated as an…
Write a program to check whether a given number is an ugly number. Ugly numbers are positive numbers whose prime factors only include 2, 3, 5. For example, 6, 8 are ugly while 14 is not ugly since it includes another prime factor 7. Note that 1 is ty…
