How to Detect if Inside Ellipse?

ericchesek

@ulrik This is really helpful too! Thanks!

@ulrik I couldn't help my self to explore this area a bit more so, in this snippet I have a function to find which area/areas is hovered (they can be on top of each other as well), so I have the rectangle and the ellipse but I couldn't find a way to get the precise area of the triangle
So if anybody with a magical knowledge of trigonometry (ustk?) could point me in the right direction I would be grateful!

The difficulties with the triangles (for me at least), how to find out if hovered inside or outside the triangle because of the radian.

@ulrik Well, getting the area of a triangle is possible with trigo but not an easy thing (I don't know how from the top of my head though I tested a while ago two mathematics way of doing it)
From here, seeing the particular shape you're using and that you are going further than simple ellipse or rectangle, the solution would be the implementation of a Juce function to detect if inside the path. (a different one than getIntersection). Then it'll be very easy and less mind torturing (even if I like that )

ustk

@ulrik Stupid me... I already added it along with getIntersection
It's Path.contains(point)

@ustk Nice one

Dan Korneff

@ustk nice job!

ulrik

@ustk Would it also be possible to add text to follow a path you think?

@ustk Hahaha....beautiful!!! cheers

ericchesek

Hahaha this is incredible. Excellent work!

ericchesek

@ustk Just to be clear, this only works with paths and not fillEllipse or drawEllipse, for example? If so, is there an API reference for what shapes can be made with paths? Similar to what you did with

const var p = Content.createPath();
p.addStar([300,300], 5, 50, 200, 0);

ulrik

@ericchesek in the API you'll find this

@ulrik Hmm, maybe I'm on an older build. 3.0.0, build 650, 2023 April 3.
I only have a fraction of these options in the "Path" API list. I'll look into it. Thanks!

@ericchesek April 3 is the date you built, not the branch date. I've implemented the new methods before that so you probably have to build the develop branch again
