It is possible an Arduino generate 3d graphics on tft or vga
On AVR based Arduinos: No, definitely not. It is possible to create a VGA signal, but only with very limited resolution and few colors (like 4 or so) and also a framerate, that will not be enough. Also they all have too few memory.

It might be possible on the Due (don't have much experience with it), but it is still a bad choice for a platform (also partly because the Due is in general such a bad designed board with no good documentation).


  Is there a library can done that?


I don't think, that you will find any library doing all what you want. You might find libraries, that help you draw on the display, but you will do all the hard stuff (creating and loading sprites, distorting them, animating them) yourself. This is, because Arduino is a bad choice for such a project.

Also: In the title you mentioned TFT. I guess you meant one of the TFT display modules, that you can connect to Arduinos. Forget about that. They are connected over rather slow serial data interfaces (not meaning the Arduino Serial here, but serial interfaces like I2C or SPI). You won't get a sufficient frame rate with them.



I would oppose your arguments against the Raspberry Pi. Sure, it has an OS, but that also means, that it can make use of a variety of languages and frameworks. You are not bound to plain C/C++. You can use the language or framework, that best suites your needs. That can be a bit complex at first to find the right one. But thats, because your project is complex. What you are describing is a very complex task, when you cannot rely on others, that have already implemented the hard stuff (which would be the case for the Arduino).

Also a Raspberry Pi has plenty of RAM and plenty of storage space. It runs at high speed and is actually capable of outputting video with a good framerate.

Without wanting to offend you: I think, as you are asking this question here, you are not qualified enough yet to do such a project on an Arduino. There are insanely capable people out there (wouldn't count myself to them), who do incredible things with Arduinos by milking the very last drop of resources out of them. But they are doing it for the grind, not for having a functioning product at the end. I guess you want this to work good at the end, without needing you to work on it for many years. Then you are result-focused and should choose the correct platform for this. A computer (like the Pi) will be easier.




  Rasberry Pi had lot of things but some of them are unnecessary.


Yes, but is that really a problem? Is the unused potential really a no-go for the project? You could say the same thing about an Arduino. It has a lot of peripherals build in (depending on type Timers, Comparators, ADCs, DACs, several communication interfaces, power management peripherals, ...). Almost no project uses all of them. But that's simply the difference between general purpose chips/boards (like all Arduinos or Raspberry Pis) and custom made chips for a single purpose. If (!) a fitting chip for your project exists, that really only has what you need, it will most likely be very expensive. Chips for a single very narrow purpose have a very narrow target group, thus are more expensive (simple economy here). Companies have formally nearly everytime designed their own chips for gaming consoles (which is way beyond your current scope), like PS1 or N64. Current gaming consoles rely often on modified standard hardware, also because it is cheaper. The really old gaming consoles used the generic electronical chips, which means, that you didn't have one single programmable chip. Instead lots of the logic was build into the electronic design.

So you will always have some excessive features, that are not used. Why would you want to remove them from the project, just for the fuzzy goal of not wasting features. It will make your project only more complex and expensive. You will gain nearly nothing from minimizing the resources. This is a hobby project, not for selling it.


  In rasberry pi you just writing a computer program.You don't have much control like arduino


That depends on what type of control you mean. On a computer you are writing code on a higher level of abstraction. That also makes it easier to do complex things, since you can rely on the low level programming of others. What control do you want to have over the system, that you don't have on a computer like the Pi? Do you think, you can program better display drivers or graphic renderers, than all the other people? Then you can still do that on the Pi. A Pi also gives you control over the GPIO pins, which let's you do many hardware things, that you can also do on an Arduino.

Also Linux is open source. If you think, you need more low level interaction with the hardware (cannot think of a reason for needing it), then you can build your own OS, which gives you the needed freedom. Sure, that is very complex. But when you are able to use the low level programming, then you are also able to change the OS.



You seem to already have chosen the Arduino for your project. I, like others, have advised you to use a Pi instead to make it a lot easier and better. It is up to you, if you want to believe us or not. All in all I'm still not convinced, that you are able to pull that off on the Arduino platform, while still getting good results. You are simply not at that point of knowledge yet. You write confidently about the problems with an OS, while you don't seem to have a concept about the exact structure of these problems and how they impact you. We will not prevent you from doing it the hard way. Please for free to choose your own way.
