使用带有C的opengl模拟粒子系统 [英] simulating particle system using opengl with C

问题描述

我试图模拟粒子系统如何形成恒星的过程。我是OpenGL的新手，所以我不知道从哪里开始。我目前正在尝试模拟可能是粒子的物体，但我不知道如何让它们聚集在一起形成一颗星星。



我搜索过互联网指南从哪里开始，但大多数文章指南使用C ++ ...问题是，我可能接近这个项目完全错误的方法，但我不知道如何处理它...我正在咨询数学家仪式现在我建议创建一个粒子，并在随机函数中调用它，我已经这样做但我不习惯opengl所以我有很多显示器的问题...我不想浪费你的时间所以我试图给你一个关于最新情况的全部概述...



我如何让粒子向一个方向移动，因为磁铁会吸引金属，因为它基本上是这样的方法，我想我需要，但我可能错了....







可以有人帮我吗？



谢谢

I am trying to simulate the process of how a star is formed by the particle system. I am new to OpenGL so I have no idea where to start. I am currently trying to simulate objects that would be the particles but I don''t know how to get it to come together to form a star.

I hav searched the internet for guides on where to start but most article guide using C++... the problem is that i mayb approaching this project on a totally wrong approach but i dont know how else to approach it... I am consulting a mathematician rite now n iwas advise to create one particle and call it in a random function and i have done that but i am not used to opengl so i am having alot of problem with the display... I dont want to waste ur time so am trying to give u the entire overview of whats going on...

How do i get the particle to move towards one direction, as a magnet would attract metals cause its basically a method like that i am thinking i need but i may b wrong....



Can anyone help me please?

Thanks

推荐答案

当然，开始的地方不是OpenGL实现，而是物理学？



获取星形成的算法排序首先，使用随机的粒子云（或定义的初始状态）并对其进行处理，直到你最终得到一颗星星，或者模糊地识别为星星的东西。当该死的东西在第一时起作用时担心演示！

Surely, the place to start is not with the OpenGL implementation, but with the physics?

Get your algorithm for star formation sorted first, using a random cloud of particles (or a defined initial state) and process it until you end up with a star, or something vaguely recognisable as a star. Worry about the presentation when the damn thing works in the first place!

这个 [ ^ ]是我能找到的最简单的解释。它分为几个步骤，它包含一些命名的公式，至少会给你一些术语来搜索。

This[^] is the simplest explanation I could find. It is broken down into steps and it contains some named formulae that will at least give you some terms to search on.

正如我们的原始指出的，你首先需要担心的是有一个合理的物理模型，然后是它的表现。

随机运动可能描述一种气体，其中粒子自由移动，即它们没有力（只有碰撞）发生）。另一方面，为了形成粒子的聚集体（像星星一样），你需要加上引力。

As pointed out by our Original, you need to worry first about having a ''reasonable'' physical model and then of its presentation.
Random motion might describe a gas, wherein the particles move freely, that is they under no forces (only collisions happen). On the other hand, in order to form an aggregate of particles (like a star is) you need to add the gravitational force.
