基于Gupta-Sproull算法的抗锯齿线 [英] Anti-aliased lines based on Gupta-Sproull algorithm

问题描述

大家好，我通常是MFC和VC ++编程的新手.我现在想做的是编写一个程序，该程序可以让我基于Gupta-Sproull中点算法来画线.有Bresenham算法，但有所不同.我相信它不会使用距离.因此，我的想法是，如果我要在鼠标上单击鼠标左键，请在屏幕上选择一个控制点，然后将其拖动到任意位置以画一条线.如果我单击右键，则结束控制点选择.通过使用此方法，我试图编写类似WAKE的内容，其中包含许多行.

我的问题是开始学习.当我在Visual Studio中创建一个项目时，它为我提供了大量的文件以供修改.我应该从哪里开始，是否有人拥有该算法的示例代码，或者如何以及在哪里使用LButtonClick和RButtonClick ...

将为您提供任何帮助.我是本示例代码的新手，这是最好的事实.

感谢

Hello everyone,
i am new to MFC and VC++ programming in general. What i am trying to do right now is write a program that will allow me to draw lines based on a Gupta-Sproull midpoint algorithm. There is Bresenham algorithm but it''s different. I believe it does not use distance. So the idea is if i''ll left click on a mouse i select a control point on the screen and then can drag anywhere to draw a line. If i right button click then i end control point selection. By using this method i am trying to write something like WAKE which consists of bunch of lines.

My problem is to get started. When i created a project in Visual studio it gives me loads of files for modification. Where should i start and does anyone have a sample code of that algorithm or how and where to use LButtonClick and RButtonClick...

Any help will be appreaciated. The fact that i am new to this sample codes are the best.

thanks

推荐答案

我只是在普通的对话框表面上绘制.创建一个基于对话框的MFC应用程序.在对话框的OnPaint处理程序中绘制线条和事物.为对话框添加按钮单击处理程序.

I''d just draw on a plain dialog surface. Create a dialog-based MFC application. Draw your lines and things in the dialog''s OnPaint handler. Add button click handlers for the dialog.
