示例1: Array
/*! Get the tesselated shape as arrays of vertices and indices
The geometry function extracts the triangle information from
the tesselated contours. It fills an array of vertices and an
array of indices with the tesselation data, which can be used
with a Mesh to draw it to screen.
<luacode>
local vertex = Array()
local index = Array()
tess:geometry(vertex, index)
local mesh = Mesh(ctx)
mesh:vertex(vertex)
mesh:index(index)
mesh.primitive = GL.TRIANGLES
</luacode>
@param vertices The vertex array
@param indices The indices array
@name Tesselator:geometry
@see Array
@see opengl.Mesh
