如何显示100浮动立方体使用的DirectX或OpenGL？ [英] How To Display 100 Floating Cubes Using DirectX OR OpenGL?

问题描述

我想显示〜100采用浮冰块的DirectX 或的OpenGL 。

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

我在寻找既一些示例源$ C ​​$ C，或技术的详细介绍。我知道这种事情很容易让你实现3D大师在那里，但我有足够的麻烦，甚至一个多维数据集才能正确显示。

I'm looking for either some sample source code, or a description of the technique. I know this kind of thing is easy for you accomplished '3D' gurus out there but I have enough trouble getting even one cube to display correctly.

我梳理了网上有一个良好的系列教程，虽然他们谈论怎么办 3D 元，我找不到是如何的信息做大量的 3D 原语 - 立方，领域， 金字塔等等。

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

你说你有足够的麻烦一个多维数据集显示...所以我不知道，如果你有一个显示与否。

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......把你的$ C $下写一个函数多维数据集，那么就调用该函数的100倍。

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();
         }
    }              
}

这是你怎么能去这样做的基本轮廓。如果你想要的东西更有效看看到显示列表的某个时候，一旦你有基本想通了：）

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 :)
