The color treatments that the original state regular prism planar graph at the place of putting is shown as the side of dotted line are the mark color；
Step 215：The display module 404 show around regular prism axis rotate to an angle after regular prism plan
Shape；
Step 216：The processing module 403 obtains the new of the postrotational regular prism planar graph bottom surface Zhong Ge summits
Plane coordinates；
Step 217：The difference of the new x coordinate value on any two bottom surface summit is calculated in the computing module 402
Maximum absolute value two bottom surfaces summit, new reference vertex is used as using the bottom surface summit that this is calculated；
Step 218：The new y-coordinate that y-coordinate value is more than the new reference vertex is calculated in the computing module 402
All bottom surface summits of value, new empty summit is used as using the bottom surface summit that this is calculated；
Step 219：The processing module 403 is by with least one for one of its end points in all new empty summits
The side of the postrotational regular prism planar graph be shown as dotted line, other sides are shown as solid line；
Step 220：The side that the processing module 403 is shown as dotted line to the postrotational regular prism planar graph is carried out
Flicker effect processing.
From above-described embodiment as can be seen that regular prism flat display apparatus provided by the invention, passes through cleverly mode pair
The plane coordinates of the regular prism planar graph midsole vertex of surface shown than plane, realizes the display of regular prism planar graph；Enter
One step, according to the sliding path for judging rotation control point, calculate and contrast bottom surface in postrotational regular prism planar graph and push up
The plane coordinates of point, it is achieved thereby that the display of postrotational regular prism planar graph；And it ensure that postrotational regular prism is put down
In the figure of face it cannot be seen that side be shown as dotted line all the time, can more vivo coordinate teaching process to show regular prism plane
Figure.
Further, can also be handled by entering line flicker to dotted line, to strengthen reminding effect, so as to attract the note of student
Meaning power；Preferably, also handled by the dotted line side in the regular prism planar graph by original state by identifying color, and follow-up
Postrotational regular prism planar graph in calculate its postrotational position and continue signal coloration processing (now dotted line
Possible or dotted line after side is rotated, it is also possible to be changed into solid line), the side being blocked at the beginning with playing displaying regular prism is rotating
Afterwards or after not being blocked effect, play a part of preferably aided education explanation.
Optionally, the deformation also by setting shape control point to realize to regular prism planar graph progress vertical and horizontal
Operation so that the content of courses is more abundant.
