Detailed Description

The VectorGraphics class is used in conjuction with SceneManagerVectorGraphics to generate and render 2D vector graphics.

The VectorGraphics object is basically nothing more than an container of Actor[s] generated by functions like drawLines(), fillTriangles() etc. The Actor[s] are rendered in the order in which they are generated.

The VectorGraphics class features a set of advanced capabilites:

Matrix transformations and matrix stack
State stack
All the blending operations supported by OpenGL
All the stencil operations supported by OpenGL
Texture mapping on all the primitives with automatic texture coordinate generation
Several primitives like lines, points, quads, triangles, line strips, triangle strips, ellipses etc.
Polygon and line stipple
Text rendering
Scissor test to clip the objects against a rectangular region
Line and point smoothing
Color logic operations

For more information please refer to the 2D Vector Graphics page.
