Beer glass scene creation
This course contains a little bit of everything with modeling, UVing, texturing and dynamics in Maya, as well as compositing multilayered EXR's in Photoshop.

software renders [MR, Vray] have to triangulate [or re-tessellate] everything at render time. everything [quads n-gons] gets tessellated into tris at render time

anyawy, when you model, you usually want to keep it all quads (unless you really know how to take advantage of the tris and n-gon's smoothness destroying ability) if you're smoothing. If the model is going into a game, use whatever you want
hope dat helped

I have commented on this topic numerous times!
I am not saying go out of you way to make ngons and triangles. Triangles are hard to avoid at times and as far as ngons they can always be turned into quads and triangles. The key is to understand how your model is to be smoothed and whether it will be deformed. Triangles are very useful in reducing mesh density and edge congestion in narrowing areas of a model and therefore can be beneficial.
In the end no matter what you build gets triangulated. From my experience maya appears to be the only program that goes ape shit when texturing non-quad models. If you look at the models built in lightwave for TV series like BSG and Stargate they boolean the piss out of their models to cut panels and windows and such using stencil and solid drill operations creating n-gons up the kazoo and go straight to production with them!
Try to bring one of those models into Maya and it would cough up a lung! I read an article where they imported the starship model (from the new stargate) from lightwave into maya and it took a week of rebuilding the model to get maya to digest it! To me that is a MAYA weakness! In an industry that is always under pressure to produce in short time frames, why add such a time and life leeching constraint as to force all model to be 100% quad? Maybe that is why those series and studios use Lightwave and not Maya. In any event the Lightwave and Modo rendering systems are lightyears ahead of maya's which has not been updated for to many YEARS!
So part of the issue with maya is its renderer is not ngon and tri frendly (in fact back in the day, around Maya 4, mental ray would not render a model at all if it had a single ngon or tri in it! You would get a blank screen). So the ngon / tri phobia has a historical context in Maya as well.
Look at Modo, Lightwave, Max just to name a few alternate modeling apps and they are far less freaked out by tri's and ngons.

maya can render non quad models just fine. Are you talking about CAD/Lidar data? this is often used in post production, it may just look like it was created from a bunch of booleans. Lidar scans will be lots of triangles.
Maya is customizable which is why companies want to use maya. The maya i'm using now is better than your maya because there is a dedicated team writing plugins for us. There is a thing called a pipeline that everyone has to work within. It is basically how a shot gets made, who does what and how it is passed around so everyone can do their job. I think you are too focused on the modeling aspect of the industry. modeling is the very first thing that is done. They are some of the first people to go home at the end of a day while others stay on to finish the shot.

Since this thread was posted, it seems it isn't just a Maya thing anymore, the game engine I'm currently modeling for will shit brix over tri's, renders them 3x longer than quads.

yeah no one cares about triangles or ngons, not unless they are modellers and then not really either.

You seem to show great displeasure at having to debate this further but then why go back and post in a 4 year old thread?I am no going to debate this point anymore.
@acid, you're not that bad, at least better than I was then....

Weird, I wonder if someone posted but then it was deleted?I did not notice the date it was at the top of the list of current threads at the time I responded!
If not, it might be wise to file a bug report or something.

thats actually a really interesting point you bring up rick, about the 'tri-phobia' going back to maya 4 and further when maya couldnt render them. makes complete sense.It's okay I just get riled up when people go on and on about the occasional triangle or ngon like they will cause the world to fly off its axis and hurl into the Sun! I have used a number of modeling packages and spend time in many forums and Maya forums are the only ones that I must say literally have what I can only describe as quad nazi's!
it is strange because i do often get the feeling that im being naughty if see an ngon or tri in a model and dont make haste to ammend it, when, more often than not, it'll never give me the slightest problem again.
not starting a debate though. each to their own. but yeah, i have never heard or read that about the early versions of maya
acid: what game engine are you modeling for? and why? what's the project?

That always sounds really cool, like your working on a top secret project for the military or something; it's usually disappointing.Can't say on either point, I'm under an NDA
I once wrote a .obj importer for openGL that would only work if the mesh you started from was entirely quads. But then it worked on the assumption that all faces were triangles....
