DAM THREE-DIMENSIONAL PERSPECTIVE DRAWING AND ITS VISUALIZING STUDY

摘要

This paper introduces the dam three-dimensional perspective drawing and its visualizing study. It is to show on its surface features and its ground objects, in the light of the topographic map (ground digit altitude model DEM) mixing with VC++ OPENGL that we are intended to work out the numerical value solution to dam excavation line and the three-dimensional dynamic Meanwhile, it can organize the design for the project and construction layout, provide precise drawing scope and theory and automatically consult the project's information. The advantages are clearly demonstrated to make up for the drawbacks on the fixed drawing during the design phases in the past, and it possesses the excellently practical project value.
