Is this site only targetting research & development in computer graphics or should it also integrate questions specific to how to use tools like Maya, MotionBuilder, etc?
Proposal: Computer Graphics
I think the Computer Graphics Stack Exchange site should be more oriented towards general Computer Graphics questions.
The Stack Exchange site 3D Modeling and Animation seems much more fitted for the kind of information you are looking for.
Computer Graphics Stack Exchange needs a variety of experts in relevant fields in order to grow and become established. We welcome questions about computer graphics hardware, software, algorithms, research, and verification of a given approach to a problem.
The site description confirms that software and hardware tools questions are on topic:
Proposed Q&A site for computer graphics researchers and programmers. Includes discussion of image processing, computational geometry and topology, ray tracing technologies, graphics libraries, gpgpu, specific graphics cards questions, and performance related questions.
Some tools questions may be off topic because they are not about computer graphics. For example, an animation question about the physics of moving bodies may be off topic, but a question about how to achieve realistic lighting effects on those bodies would be on topic. This could be a general question about a given lighting effect, or a specific question about achieving the lighting effects using a particular tool (software library/graphics card).
From what I gather, there are two distinct requirements for this site.
The first is a subject relevant to CG in the theoretical or applied sense. The second involves writing code or algorithmic concepts with respect to the topic chosen in the first requirement.
As long as those two are met, I'm pretty sure you're green.
I think tool related questions that have unambiguous answers that aren't immediately or obviously available in the documentation, or even answers that tend to have a long life and contain valuable info, should be allowed. E.G. "is Maya's DG pull/push or pull only?", that usually narrows it down to what a lot of people would call "technical".
I would consider fluff anything that can be answered immediately by the documentation or readily available web sources, E.G. where is this button? Does Houdini support GPU compute?.
I would consider totally off limits open ended questions that require a tutorial form . E.G. "How do I start modelling a car?".
As long as the right group of users participates actively and early, for some definition of right, you can shape stack sites pretty well, the beauty of meta moderation. Overflow is a chief example of that, and the one I would like to see this stack largely modelled around.
Bear in mind that directing and shape CAN actually be explicitly encouraged a great deal based on what badges become available too; we should never under estimate the achievement 'ho in any and every one of us.
