Talk:Cohen–Sutherland algorithm

[Untitled]

what is outcode is the point is on the line x=x_min or x=x_max or y=y_min or y=y_maz ? please help me

It has to be INSIDE when it's on the boundary, otherwise the loop will never terminate (unless both points are initially INSIDE.) 2620:79:0:165:1A03:73FF:FE20:3C3B (talk) 01:30, 13 November 2012 (UTC)[reply]

Implementation

if (!(outcode0 | outcode1)) { // Bitwise OR is 0. Trivially accept and get out of loop

Wouldn't logical OR be faster and more intuitive here? Also, shouldn't the whole algorithm be rewritten using Allman indentation style? And the last point, shouldn't we use use more structured approach? while (true) and breaks may be not friendly for beginners. My opinion. FaTony (talk)

I think the code is missing the definition of the TOP constant: const int TOP = 8; // 1000 Curiousdolphin (talk) 13:20, 28 December 2022 (UTC)[reply]

License?

Where was the C/C++ example source code taken from? Is there a license to go along with it? Stéphane Charette (talk) 08:54, 22 February 2017 (UTC)[reply]

I was wondering the same thing. The oldest edits that add code have no references at all, and Wikipedia user edits complicate the matter further. Looking around online, a lot of sources link to a page on geeksforgeeks.org, but that page literally states it got the code from this wikipedia page. Full circle... -Nyerguds (talk) 12:34, 7 August 2025 (UTC)[reply]
