Translations

How would I modify this with a triangle and make sure the dots stay inside?

void setup() { size(200, 200); }

void draw() { background(255); stroke(0); fill(175);

int mx = constrain(mouseX, 0, width); int my = constrain(mouseY, 0, height);

translate(mx, my); ellipse(0, 0, 8, 8);

translate(100, 0); ellipse(0, 0, 8, 8);

translate(0, 100); ellipse(0, 0, 8, 8);

translate(-100, 0); ellipse(0, 0, 8, 8); }

I'd start by drawing the triangle that you want the dots to remain inside.

From the points you have: store them in an array and for loop over it

Find out here which is the lowest and highest x and y and use those values for your triangle

void setup() {

size(500, 500); smooth(); }

void draw() {

background(255); stroke(0); fill(175);

// Grab mouse coordinates, comstrained to window

int mx = constrain(mouseX, 0, width); int my = constrain(mouseY, 0, height);

//Translate to the mouse location translate(mx, my); ellipse(0, 0, 8, 8);

// Translate 100 pixals to the right translate(100, 0); ellipse(0, 0, 8, 8);

// Translate 100 pixals down translate(0, 100); ellipse(0, 0, 8, 8);

// Translate 100 pixals left translate(-100, 0); ellipse(0, 0, 8, 8); }

No.

It has been explained to you in the other thread how to format your code correctly

Please edit your posts and fix the code formatting.

Given a square of points, many different triangle could enclose them -- a right triangle, an isosceles, equilateral etc. etc.

What kind of triangle do you want? Should one or more of the points be touching the triangle edges? All four points?
