CAD System For Spherical Triangle Based On OpenGL

There are many methods for space angle calculation in the filed of current handwork calculation, such as hexahedron, perspective geometry etc, but most of jobs in cyber-arithmetic still need further study for these methods. In current industrial design and manufacture, people still can not find a simple and flexible way for space angle calculation, and furthermore, look for a systemic and whole software to apply easily by engineering personnel. In the CAD system for spherical triangle based on OpenGL, a simple and effective way is put forward for the problem.The subject primary works in this paper are as follows.(1)There is a problem that how to show graph of differ angle spherical triangle con-ectly in the plot. So the spherical triangle are divided into three species, simpler arithmetic may be realized separately for every spherical triangle.(2)The system can solve these calculative problems such as three-peak coordinates of spherical triangle, spherical triangle's area and perimeter, angle size and side length etc, and temporal complication of design is rather superior.(3)The system designs and achieves a spherical triangle's calculation, and a showing assistant design of computer, the system have these functions such as defluxion, showing two-dimensional and three-dimensional graph, real romance, and documentary storage etc.
