Assembly 如何用汇编语言绘制正方形？
我想用汇编语言画一个正方形。我骑过一些关于Assembly 如何用汇编语言绘制正方形？,assembly,Assembly,我想用汇编语言画一个正方形。我骑过一些关于int10h的车。有人知道怎么做吗？请在这里放置一些代码，告诉我可以使用什么来绘制正方形，或者一些高质量的教程。谢谢。正如弗雷德里克·哈米迪所说，“int 0x10h”是一个过时的BIOS接口。如果您对汇编感兴趣，我强烈建议您避免使用16位DOS/Masm教程，并在更现代的操作系统（如Linux）上学习 我强烈推荐Jonathan Bartlett的“从头开始编程”： 然而，如果您真的想在16位实模式（即DOS）下绘制直线（或正方形），下面是一个示例：
int10h我能想到的做这样的事情的唯一可能的原因是在原始形状光栅化的方式上获得经验。正如评论者所指出的，你真的不能再在你的CPU的汇编语言中做这种事情了，如果有的话。现代计算机有显卡。也许你想学习如何与那些设备驱动程序对话？或者你也可以使用像WindowsGDI这样的半可移植API。这个问题的变数太多了 只是为了好玩，这里有一个轻率的回答。您可以从汇编语言程序访问OpenGL API。几年前（确切地说是2002年），我有一台Windows机器，并编写了一个NASM程序来绘制著名红皮书开头的彩色三角形。你可以调整它来画一个正方形。这是：

真的，我不想麻烦你。它唯一的价值是演示汇编语言调用，实际上。
