Answer 2

just use three.js. making your own 3d engine would require huge amount of codes and concerns regarding performance. for 3d engines you have to use WebGL renderer instead of the traditional canvas2d renderer as 3d rendering requires more gpu usage and canvas2d is not elegant for it. even drawing a rectangle on webgl renderer takes a lot code.
