Abstract

The invention relates to the technical field of education and teaching, and provides a geometrical stereoscopic graph projection device and projection method. The projection method comprises the following steps that a two-dimensional plane graph is obtained; whether the two-dimensional plane graph is a geometrical stereoscopic graph or not is judged, if so, one point in a located interface of the two-dimensional plane graph is selected to be used as the original point of a two-dimensional coordinate system, and a boundary point coordinate of the two-dimensional plane graph is measured according to the original point of the two-dimensional coordinate system; the boundary point coordinate of the two-dimensional plane graph is subjected to coordinate transformation, and the three-dimensional coordinate of a boundary point is obtained; a three-dimensional stereoscopic graph is obtained according to the three-dimensional coordinate projection of the boundary point. The simple geometrical stereoscopic graph is subjected to graph analysis, processing and conversion, the stereoscopic graph with the three-dimensional effect is projected, the interactive competence of teaching is improved, the stereoscopic graph can finally help students to understand the three-dimensional stereoscopic graph, and the space imagining ability of students is improved.

Description

technical field [0001] The invention relates to the technical field of education and teaching, in particular to a geometric stereographic projection device and projection method. Background technique [0002] The basic elements in the geometric system have been increased from "points, lines" to "points, lines, surfaces", from plane graphics to spatial graphics, from "two-dimensional space" to "three-dimensional space", which is very important for students' three-dimensional space imagination Higher requirements are put forward for all aspects of ability, such as logical thinking ability and logical thinking ability. However, for those students who are in the middle school education stage, this kind of abstract imagination is exactly their weakness. In addition, coupled with the imperfection of the current electronic teaching equipment, it is difficult to display the sense of graphic space, and it is also difficult to carry out teaching interaction. For example, in order for...
