Helix Curve를 그리는 동안이 오류가 발생합니다. 최신 Curve.js와 TubeGeormetry.js를 추가했습니다. 캔버스 렌더링 때문입니까, 아니면 제가 잘못하고 있습니까? 나는이 예제는 제대로 곡선 객체를 인스턴스화되지 http://mrdoob.github.com/three.js/examples/webgl_geometry_extrude_splines.htmlthree.js - Uncaught TypeError : Object function() {}에 'getTangentAt'메소드가 없습니다. TubeGeometry.js : 175
