Research On Lunar Soft-Landing Visible Demo Key Technique

Lunar exploration is a high risk, high investment, complication system engineering. It is important to validate the system feasibility again and again method before carrying on using simulation. This paper mainly discussed the theory of Visualization demo technique and lunar the development of a soft-land scene simulation demo system.Scene simulation technique owing computer graphics technique, computer simulation technique and computer display technique, has been widely applied to the aviation aerospace, military training and medical science. This paper researches deeply the scene simulation technique, Creator 3D modeling tool and Vega Prime developing environment. This paper also describes the HLA simulation platform and OpenGL low graphics library knowledge, even analyzes the modeling method for the characteristic of scene simulation system.This paper designs the fragment of scene simulation based on Vega Prime, of which emphases are researching of combine of Vega Prime and MFC, scene rendering driving, image key frame disposal, drawing method of points track under explorer and correspondence technique. Apply scene simulation technique to real projection.This paper resolves many key techniques of scene simulation based on Vega Prime, for example, designing the proper timer for highly precise simulation cycle from lower layer of computer hardware, drawing points under explorer on lunar globe, constructing the engine flame with particle system in Vega Prime according to theory of deep space flame and so on. For some functions couldn't be solved by Vega Prime, this paper advances methods based on OpenGL which has been applied to orbit drawing of explorer and characters displaying in channel.
