zePolygon

Use .new("polygon") to create the object. This is one of the shape objects that the OpenGL display list is implemented. A polygon object is compiled into a display list if activated through the render. By default the object is treated as filled GL_POLYGON. Improperly setting the polygon type is the most misuse of the object. Check whether you have set the type correctly when the rendered result is not what you anticipated. The order of calling translate, scale, and rotate function is important.

:rotatex(angle)
:rotatey(angle)
:rotatez(angle)

These functions rotate the object around the x-, y- and z-axis, respectively. The calling order matters.

:reset()

Resets the transformation to none.

:scale(xs, ys, zs)

Scales the object in x, y, and z direction for the factors of xs, ys, and zs.

:translate(dx, dy, dz)

Moves the object dx, dy, and dz away from the current position.

:update()

Forces to update the rendering of the object.

:set{...}

Sets polyogn properties with a Lua table. Valid key-value pairs in the Lua table are listed as follows.
