求翻译：本项目提供一个方便的编辑符号的平台，用户可以将点、直线、弧线、三角形、圆形、多边形等多种基本图形组合构成符号，这些符号库可导出为OpenGL绘制代码以实现符号库的跨平台使用是什么意思？

This project provides a convenient platform for editing symbols, the user can point, line, arc, triangle, circle, polygon graphics portfolio composition and other basic symbols, these symbols libraries for OpenGL drawing code can be exported in order to achieve the symbol library Cross-platform

This project provides a convenient platform for the symbol editor, the user can point, straight, ARC, 3 triangle, round, polygonal, more basic graphics portfolio symbols, these symbols can be exported to OpenGL mapping code to achieve the cross-platform use symbols

This project provides a convenient edition mark the platform, the user may select, the straight line, the arc, the triangle, the circular, the polygon and so on many kinds of basic graph combination constitution mark, these mark storehouse may derive is the OpenGL plan code realizes the mark storeho

Edit symbol of this project provides a convenient platform, users can apply points, straight lines, arcs, triangles, circles, polygons and other basic graphic combination of symbols, these symbols can be exported as in cross-platform OpenGL rendering code to implement a symbol library
