Because of recent years network technique progresses unlimitly, and accompanies with people pairs of the need of the teaching quality; therefore distance learning 2D image teaching can not satisfy present condition. The study at 3D distance learning environment below make use of three cameras retrieval article different angle image, Furthermore retrieval image will appear the article of the 3D and this article send to Web page which can be studying. Make uses to understands to teach scholar that want the teaching of expressed contents clearly. This research divide into three parts, the difference carry for : retrieval ,server and client. This three aspects comes to attain us the 3D of that presented teaching, we don't need expensive three-dimensional equipment, just make use of 3 cameras and a personal computer, therefore we reduce the cost. We will make use of at distance learning teaching on, come improves formerly the teaching of 2D image. Let the contents of the teaching attract to study, furthermore let to study to understand the contents of knowledge.
