Can you determine if two lines lie on the same straight line? For instance:
line1Start [0,0,0]
line1End [10, 0, 0]
line2Start [12, 0, 0]
line2End [15, 0, 0]
I am in need of a reliable method to ascertain whether these two lines are on the same level.
I have already tried using threejs methods to check their direction, but it did not provide a conclusive answer.
function checkCollinearity(a, b, p) {
const riseOverRun = (coor1, coor2) => (coor2[1] - coor1[1]) / (coor2[0] - coor1[0]);
const slopeXY = riseOverRun(a, b);
const slopeXZ = riseOverRun(a, p);
const slopeYZ = riseOverRun(b, p);
return (slopeXY === slopeXZ && slopeXZ === slopeYZ);
}
checkCollinearity([0, 3, 5], [10, 3, 5], [12, 3, 5]); // true
checkCollinearity([0, 3, 1], [10, 3, 1], [12, 3, 7]); // falseAfter successfully compiling my project for production using the command ng build --prod, I made sure to implement certain production settings in angular.json: "production": { "fileReplacements": [ { "replace": "src/environments/e ...
