Is it possible to output 3D graphics on NES?

Question

3D

Tell me, were there any projects by enthusiasts to create demos or games using "honest" 3D on the NES?

Answer 1

No. That is, yes. But not really. Read to roughly understand what the NES can do.
Okay. What does the NES have? 1.5 megabytes of CPU, yes a couple of kilobytes of RAM. Plus 5 megahertz of a very specific GPU, which can only draw sprites, also having a couple of kilobytes of memory. Given such very limited characteristics, it is not possible to create a real 3D - NES, which is funny, does not even know how to slow down. So the output is kind of isometric, with very weird background scrolling and a very simple scene.
However, perhaps there is an option in order to cheat on the cartridge: there we can add a little more video memory, which we can try to change directly, from the outside, in the cartridge itself. But it's not the NES anymore.

Answer 2

Is this possible?

the first elite will pass for 3d?
