Description: 三维表面图形控件是建立在OpenGL基础上的控件，给定zij=f(xi,yj)离散数据，可以绘制三维表面图形。三维图形的表面可以使用不同的颜色、光照、纹理，也可以控制其绕x、y、z轴旋转，还可以通过随时间而改变控件中的数据，制作随时间变化的动态图形。三维表面图形控件包含的文件有：matview45.ocx，gl3d20.dll，CqmImg32.dll，Visdp32.dll。-Three-dimensional surface graphics control is built on the OpenGL-based controls, given zij = f (xi, yj) discrete data, you can draw three-dimensional surface graphics. The surface of three-dimensional graphics can use different colors, light, texture, you can control its around the x, y, z-axis rotation, can also change over time in control of the data, the production of time-varying dynamic graphics. Three-dimensional surface of graphical controls contained in the documents: matview45.ocx, gl3d20.dll, CqmImg32.dll, Visdp32.dll.
