I don't know much about science, but can someone explain to me why video games have so much difficulty generating a circle?

Why is it so difficult? Video games always seem to make circles with straight lines, which is incorrect.
>>
You'd need infinite polygons.
>>
>>381896660
Why not just use circles instead of polygons?
>>
>>381896775
Circles can't be calculated mathematically. See the digits of pi for reference. An approximation must always be made.

this might be the dumbest thread I've seen in a while

I don't understand how that shit equates to video games, though.

We can have nuclear bombs and shit but we can't find a way to generate a circle in a video game?

What practical applications could there be from this? How useful would those be?

I wouldn't want to bother with it honestly. The approximations done today work well enough for what they are used for that there's no pressing need to go beyond that. Sure, you could research it, publish a textbook on it, teach a class at a shitty university on how to make the perfect circle in a digital format but who is going to care?

What I'm trying to say is its probably not being researched because people see that kind of thing as a waste of resources and time. And it would be folly to chase after it because all you'd come out with is a slightly useful thing only a few unimportant people in the world would care about.

Okay, first off I've come to the conclusion that the number zero must go if Perfect-Mathematics is to get off the ground.

Due to Quantum Particles borrowing energy from the future that means that zero as a concept should be gone in Perfect-Mathematics and is the big downfall of Approximate-Mathematics and why it is so flawed.

With this as the first step, I believe the perfect circle can be done.

>I don't know much about science, but can someone explain to me why video games have so much difficulty generating a circle?

3D
The most commonly used rendering techniques use triangles to generate 3D shapes. Each triangle is stored as 3 edges. Each edge is stored as 2 points. Everything in-game must be composed of triangles - even circles.

In 2D, one can just draw as perfect of circle as the pixel resolution permits. 2D also has the possibility of vector graphics, which can make all sort perfect shapes.

However, there actually is a way to generate perfect circles and/or spheres. Its called "raycasting" rendering. It works by shooting out one ray for each on-screen pixel and detecting with what colored surface it bumped into and then turns that pixel into that color. The rays can be even made to bounce, which will generate 100% accurate mirrors. Then one has to determine, how many bounces is too many bounces.

How that raycasting can do circles and spheres perfectly? Each circle or sphere is represented by its formula and its attributes like radius and position. When the ray is cast, it is calculated whether the ray intersects that sphere or not. And if it does, then the point of intersection is calculated. Then the light sources are considered in relation to that intersection point to determine the brightness of that point. Then the pixel is colored accordingly.

You can go as close to the sphere as you want, it will still not display any visible polygons.

However, that rendering technique is VERY demanding. It is so demanding that rendering a 4K picture can take minutes. Thus, that rendering technique is only used in applications where framerate is not important, like final rendering of a disney animation.

This rendering technique could work if players would be willing to limit themselves to 600x480 screens.

Cool, so we can get perfect circles in video games in about 30 years.
>>
>>381896775
because modern videogame engines can only render flat surfaces, all of the rounded edges you see are flat edges placed to look circular

since, to a computer, a circle is a one sided object (because it loops infinitely) it can't render it. you can create models of circles if you place the polygons correctly, but it can render and entire circle, because it can only render flat sides

I may do this, but I want to get the groundwork down first so people know it's not a scam.

>>381899693

Thanks for the support.

Now, I believe with this in mind we get onto the first problem which is how we can control when the energy is 'borrowed'. The less time the energy is borrowed, the more that can be borrowed. With this in mind I believe if we create what I will name, for now, the 'Variable Zero' as the core of Perfect-Mathematics.

The 'Variable Zero' is the idea that, with the right piece of technology we could control this borrowing allowing us to dictate exactly how much 'Variable Zero' is worth.

It is my believe that doing this will allow us to rid the problem of making the perfect circle as I propose that the perfect circle is unable to be done due to fluxations in energy that stop the perfection from happening.

We can remove it when we move onto the 'Variable' system instead of using Binary. I would like to think it's be a slow process of new/superior technology phasing out the old not a complete destruction and starting from zero.

I actually believe using the 'Variable' system, derived from Perfect-Mathematics' and using the technology to control 'borrowed energy' we could have computers that code with the 'Variable Zero' and 1's.

'Variable Zero' is in essence never zero but an actual amount. As I described earlier I believe that the perfect circle is impossible due to the fact that we can't control 'borrowed energy' which interferes with the perfection.

So with the right technology we could control this interfering energy and make it what we want for the time we need it, which is why 'Variable Zero' could never be zero. As of this point I don't know exactly how we should number the energy borrowed as we'd need to find the upper limits to what we could borrow, as the rules seem right now we can borrow more the less time we need it but it must always return within a certain timeframe.

To keep it simple I believe measuring it in 0.1, 0.2 etc would be too simplistic and so I propose that the 'Variable Zero be shown as 0!1. 0!2 the ! can refer to the borrowing of energy from the future. So we could have 0!5 + 2 = 2!5, this is a rough example of 'Perfect Mathematics' as it is still in its infant stage. We would also know how long the 'borrowed energy' was borrowed due to the number.

Zero would still exist however with 'Variable Zero' it's more that its value would never be counted in 'Perfect-Mathematics'. You could easily do !5+2= 2!5 and it's the same but to express the concept at this early stage putting zero in front of !5 (0!5) is the easiest way to show the process.

>>381906330

I suppose but it's more controlling a force from the future which I believe interferes with the attempt of making a perfect circle.
