使用DirectX或OpenGL显示100个浮动多维数据集 [英] Displaying 100 Floating Cubes Using DirectX OR OpenGL

问题描述

我想使用DirectX或OpenGL显示100个浮动多维数据集.

I'd like to display 100 floating cubes using DirectX or OpenGL.

我正在寻找一些示例源代码或该技术的描述.我无法获得更多的多维数据集以正确显示.

I'm looking for either some sample source code, or a description of the technique. I have trouble getting more one cube to display correctly.

我已经为一系列好的教程精通了网络，尽管他们讨论了如何做3D原语，但我找不到的是有关如何做大量3D原语的信息-，spheres，pyramids等.

I've combed the net for a good series of tutorials and although they talk about how to do 3D primitives, what I can't find is information on how to do large numbers of 3D primitives - cubes, spheres, pyramids, and so forth.

推荐答案

您说要显示一个多维数据集有很多麻烦...所以我不确定是否要显示一个多维数据集.

You say you have enough trouble getting one cube to display... so I am not sure if you have got one to display or not.

基本上...将用于编写多维数据集的代码放在一个函数中，然后只需调用该函数100次即可.

Basically... put your code for writing a cube in one function, then just call that function 100 times.

void DrawCube()
{
    //code to draw the cube
}

void DisplayCubes()
{
    for(int i = 0; i < 10; ++i)
    {   
         for(int j = 0; j < 10; ++j)
         {
             glPushMatrix();
             //alter these values depending on the size of your cubes.
             //This call makes sure that your cubes aren't drawn overtop of each other
             glTranslatef(i*5.0, j*5.0, 0);
             DrawCube();
             glPopMatrix();
         }
    }              
}

这是您如何执行此操作的基本概述.如果您想要更有效的方法，那么一旦掌握了基本知识，就可以在一段时间后查看显示列表":)

That is the basic outline for how you could go about doing this. If you want something more efficient take a look into Display Lists sometime once you have the basics figured out :)
