Hypercube是一款跨平台的 SVG 图像展示开源工具。支持Window, Linux, 以及Mac OS平台。拥有基于QT编写的用户界面，目标是便携性和易于使用性。同时也可以是命令行形式的工具。采用模拟退火算法（simulated annealing algorithm）的布局图，可以很容易地参数进行调整，来达到所需的外观。命令行工具可以不依赖其他的库，独立运行。 相关文件下载地址 本地直接下载 来源： oschina 链接： https://my.oschina.net/u/4257044/blog/4284345

Hypercube with multidimensional vectors

由 梦想的初衷 提交于 2019-12-30 07:32:10
问题 I'm trying to implement a hypercubeclass, that is, multidimensional vectors. I have a problem generalizing it. I'm able to make one for a three dimensional hypercube, but as mentioned, the problem is generalizing it. Could anyone help me? You should be able to write hypercube<4> w(5) to get 4 dimensions and 5 elements in each vector that is 5*5*5*5 elements in total. Here is the code I have for the three dimensional version: #include <vector> using std::vector; using namespace std; template

4D to 3D perspective projection

问题 Im trying to calculate the position of 4D point in 3D world. I started with 2D and tried to extend it to the 3D and then to 4D. Firstly, I found out that its easy to calculate the projected position of 2D point on the line. Whoops, there should be () in the first equation: x/(a+y) Now I figured out that the same will apply in the 3D world if I split the P(X,Y,Z) to the P1(X,Z) and P2(Y,Z), calcualte their Q and then build a point of P'(Q1,Q2) (Assuming Im looking Z axis positive infinity from

C++ How to generate the set of cartesian product of n-dimensional tuples

由 ≯℡__Kan透↙ 提交于 2019-12-07 05:33:59
问题 I wish to generate some data that represents the co-ordinates of a cloud of points representing an n-cube of n dimensions. These points should be evenly distributed throughout the n-space and should be able to be generated with a user-defined spacing between them. This data will be stored in an array. 回答1: I have found an implementation of a cartesian product using Boost.MPL. There is an actual Cartesian product in Boost as well but that is a preprocessor directive, I assume it is of no use

问题 Hey, i am starting a hadoop based hypercube with a flexible number of dimensions. Does anybody know any existing approaches for this? I just found PigOLAPSketch, but there is no code to use it. Another approach is Zohmg from lastfm, which uses hbase, but seems to be very dead. I think i will start a pig solution, maybe you have some advices? 回答1: This would be very cool/useful. OpenTSDB is an HBase time-series database that might be interesting to look at, they have a clever approach to
