3.4  3-DIMENSIONAL PERSPECTIVE DRAWING 
This research was expressed the drawing result to be the vector about each pattern with whole structures by projecting 
and transforming it with same coordinates system and completed perspective drawing for adding the visual analysis 
effect of whole form. This research was executed the moving image analysis to use precise digital data by storing the 
image that this research was executed modeling by rotating view direction by 10 with the perspective drawing 
analysis in diverse directions as image. 
35 ANALYSIS OF CONTOUR 
As the sound of bell has something to do with the pattern of relief, the pattern of Yuguwk was used, so that it may 
control the sound ofthe bell. As the sound of the bell is different in accordance with the positions of dangjwa to be hit 
at the time of striking a bell, the analysis data to be able to know relative height value with the form by parts about 
patterns is required for precise sound analysis. For this, in this study, this researcher made out contour map on the basis 
of TIN model. Figure 6 is the result that this research was drew the contour map of 1 Xabout dangjwa. Then, this 
research could offer it as the basic data for fine art history study and sound analysis.

3.6 PROJECTION DRAWING OF PLAN 
So as to execute the projection analysis of 2D plane about the surface of the temple bell, this research was projected 
and transformed by making the direction of bell circumference of X axis and the height direction of Y axis on the basis 
of lower end of the bell. As we may compare the relative position and form of each pattern on plan, it is considered that 
it will be utilized as the basic analysis data for the analysis of plastic beauty and the study of fine art history. Projection 
points are the defects of TIN. Then, this research was projected and transformed 3-dimensional coordinates of these 
points with 2 dimension. This research could make out the projection drawing of plan of figure 7 by storing the 
coordinates result of each edge point to constitute TIN with ASCII file and completing DGN file through using it as 
data file.
