i'm trying draw line between 2 moving vertices. vertex's drawing stored in variable called object , has position , three.vector3 . the line created thusly: var line = function(scene, source, target){ var geometry = new three.geometry(); geometry.dynamic = true; geometry.vertices.push(source.object.position); geometry.vertices.push(target.object.position); geometry.verticesneedupdate = true; var material = new three.linebasicmaterial({ color: 0x000000 }); var line = new three.line( geometry, material ); scene.add(line); return line; }; ..., source , target vertices , vertices updated via: vertex.object.position.add(vertex.velocity); now, assigned source.object.position , target.object.position line.geometry.vertices[0] , line.geometry.vertices[1] because wanted 1 update other. instead, vertex positions vary wildly line positions. vertices are, lines don't connect vertices. how can make lines move vertices? in animation loop ha...
