Turn this into a circle without acting like it was a circle all along which only needed turning 90deg towards the perspective

Protip: you can't

No, it''s about turning strict 2d illusion into 3d illusion

The answer: define a function that maps every point from that thing to a point on a circle.

There are infinite amount of points there. You can turn it into everything. It's like an infinite amount of clay.

That's acting like it was a circle all along and turning it

extend the line into the edges of the image
its a circle, just huge

you'd have to add a point for that like >>11367077 suggested, since the opposite side would lie at infinity

you're going to have to define what you mean by "turn into". Give us some rules here. All you did was remove one possibility

Stretch space so it appears as circle from this perspective? im thinking shear and extend?

You cant without changing its homotopy type LOL

who said anything about conserving its homotopy type? The question doesn't even state it has to remain a line.

It's just a faggy question by a faggy op to waste our time

Cut the segment in half, then cut the remainders in half x number of times, reassemble the pieces so they resemble a circle,

Tilt the image horizontally, in such a way that the line appears shorter and shorter. Far enough, and the only thing visible will be the ends, which are round.

Otherwise, bend the line until the two points connect.

Quoted By:

>>11367057
x is the horizontal lines
y will be the vertical lines
left edge is 0
right edge is 2
middle is 1
for every x, raise a vertical line from it
the vertical line for x is 0 unit-lenght tall for x=0 and x=2, and 1 unit-lenght for x=1
and the lines between follow $y = \sqrt{(1-(x-1)^2)}$
how 'bout this?
