A lot of graphics questions are asked on SO or gamedev (and possibly others?). It'd be very useful IMO if our site search tool could search some of these other sites as well. You can of course search on the main stackexchange site to search all sites, or use filters to build a multisite search (but then you have to edi... |
Add multisite search capability? |
I recently posted a comment that had an error in the math I had posted $a^3t+b^2t+ct+d$ but should have posted $at^3+bt^2+ct+d$. I didn't see the (brain dead) mistake till after the 5 minute window closed and the site went down for maintenance directly after that. In the meantime the person who asked the question had g... |

As [discussed on Meta Stack Exchange] there are problems with link only answers. [This Meta Computer Graphics post] suggests our particular community would prefer not to have link only answers. However, having established that they are not good, there are a number of different ways of responding to them. Today we have ... |
In my opinion we should discourage link only answers, too.
Links to external resources are great to provide extra information to the question, e.g. like further reading material, but even if all links are broken in an answer, it should still be a helpful answer. So at least the most relevant information from *behind... |

Although computer graphics can be seen as part of programming, or part of game development, there are aspects that most programmers will not necessarily be good at or even familiar with, and there are areas of computer graphics not used by most game developers, with conflicting requirements and priorities.

While on some SEs, notably Stack Overflow, it is often sufficient for questions to contain a short code snippet, others, notable TeX/LaTeX SE, ask for a full [Minimal Working Example (MWE)](https://tex.meta.stackexchange.com/q/228/18957).

[This question] asks for definitions of two terms commonly used in computer graphics. Is this a type of question that we want to see here?

Questions and answers are often edited following a query in a comment to expand or clarify something. This is clearly a good thing. What I want to discuss here is that sometimes this is edited prefixed with "Edited to explain..." or "Edited following the comment from...". For example, [this answer].

[This question] asks how to complete an artificial task that is unlikely to be useful in a practical graphics setting, but is part of learning the basics about a graphics library. Does that make it on topic as part of learning, or off topic as a homework problem with no practical application?

[This question] has 2 downvotes at present, but no close votes. There is a comment suggesting that the question is unclear, which is a valid close reason, but I don't know whether both the downvotes are for this reason.

[This question] has been edited to add a second part. It is a homework question and the second part follows on from the first, so they are related but seem like distinct questions. The second part was added after an answer came in for the first part.

We currently have 2 questions tagged [tag:space-filling]. The first is a [question] about *[space filling curves]*. The second is a [question about] GPU fill rates.

The question https://computergraphics.stackexchange.com/questions/1783/liang-barsky-line-clipping-algorithm asks for an extension to n dimensions, but does not specify how the extension will be made, leaving the potential for ambiguity as Nathan Reed points out in a comment.

On the main site, we have the tag [tag:algorithm] and I'm a bit confused about the purpose of this tag.

[This question](https://computergraphics.stackexchange.com/q/1903/16) made me wonder whether questions about creating simple 2D plots are considered on topic or not.

The question https://computergraphics.stackexchange.com/questions/1983/need-a-reputable-source-for-the-formula-for-the-shape-of-earths-horizon is solely seeking a source for a known formula, rather than asking for explanation or derivation of that formula.

Although our [percentage of questions answered] is good, we've been around long enough now to have built up quite a few [unanswered questions].

[This question] initially had the term "EL" in its title. As the question asks about the meaning of $E_L$ in an equation, I've edited to show MathJax in the title, so it is clear that a subscript is intended.
