how would I check if hyperbolic 2 lines intersect? about hyperbolic-canvas HOT 13 CLOSED

also how would I get the angle of 2 hyperbolic points?

from hyperbolic-canvas.

There was a small error in the function. It should be fixed now. Thanks for pointing it out.

I'm not sure what you mean by your second question.

from hyperbolic-canvas.

Math.atan2(x0-x1,y0-y1) <-- whatever the hyperbolic equivalent of that is

from hyperbolic-canvas.

I'm not sure what Math.atan2(x0-x1,y0-y1) means in a Euclidean sense. However, it is my understanding that, because the Poincaré disk model is a "conformal mapping," angles may be measured using Euclidean logic. No conversion is necessary for angles.

Math.atan2(x0-x1,y0-y1) gets the angle of:

var x1=x0+Math.sin(angle) * distance
var y1=y0+Math.cos(angle) * distance

do you know how I would do this?

from hyperbolic-canvas.

I've added a function for this.
Point.angleTo(otherPoint)
Let me know if you find errors.

https://github.com/ItsNickBarry/hyperbolic-canvas/blob/gh-pages/lib/Circle.js#L26 is this correct?

from hyperbolic-canvas.

nevermind.

from hyperbolic-canvas.

seems to be correct

from hyperbolic-canvas.

is Point.angleTo(otherPoint) suppose to get the angle is hyperbolic space? It doesn't seems to work. I converted the code into rust because javascript is to slow. My rust version doesn't get the correct angle.

from hyperbolic-canvas.

The hyperbolic line between point A and point B is represented by an arc of circle C. A.angleTo(B) should return the angle of the slope of the line tangent to C at A, in the direction of B.

In this example, A is (.5, -.5) and B is (.5, .5). The result of A.angleTo(B) is 2.0344439357957023. This is the angle of the shown tangent segment to the arc, the angle towards B from A.

I fucked up while converting your code to rust.
