COMPUTING DEVICE AND METHOD FOR SIMULATING PROCESS OF SCANNING DRAWING OF OBJECT

摘要

A computing device and a method simulate a process of scanning a drawing of a three-dimensional (3D) object. The computing device triangulates a three-dimensional (3D) object using a plurality of 3D triangles. The computing device obtains converts the drawing of the 3D object into a drawing of a two-dimensional (2D) object. The computing device obtains 2D triangles from the drawing of the 2D object and displays the 2D triangles onto the drawing of the 3D object.

1. A computing device comprising:
at least one processor; and a storage device coupled to the at least one processor and configured to store one or more programs, which when executed by the at least one processor, cause the at least one processor to: triangulate a drawing of a three-dimensional (3D) object using a plurality of 3D triangles; generate a two-dimensional (2D) image of light and define an origin point and a normal vector; generate a projection area according to the origin point and the normal vector; project the 2D image of the light into the projection area; obtain a 2D projection surface; project the 2D projection surface onto the drawing of the triangulated 3D object; obtain a drawing of a 2D object from the projection of the 2D projection surface onto the drawing of the triangulated 3D object; obtain the 2D triangles from the drawing of the 2D object; and display the 2D triangles onto the drawing of the 3D object.
