Proposal: Computer Graphics
A lot of potentially very interesting questions are closed as subjective or out of topic on Stack Exchange, including some popular "historical" ones. This trend has spawn quite some discussion. The guidelines state for example that:
Thus, questions that are not answerable — discussions, debates, opinions — should be closed as subjective.
Computer graphics are full of problems with no clear definitive best answer. I understand from the guidelines that questions about such problems don't belong here and should be discussed somewhere else. But if this means going to some other place every time a problem is open ended, it feels like a loss both for the user and this Q&A website.
How can we prevent some entire topics from excluded?
The question "How can glossy reflections be implemented efficiently when using Image Based Lighting?" (from the Example Questions) sounds to me both valid yet at risk of getting moderated away under such rules.
