Common graphic functions are as follows:

1. ccDrawColor4B (GLubyte r, GLubyte g, GLubyte B, GLubyte a) // set the painting color

Parameter 1: red

Parameter 2: green component

Parameter 3: Blue

Parameter 4: Transparency

2. glLineWidth (GLfloat width) // you can specify the line width.

3. ccDrawLine (const CCPoint & origin, const CCPoint & destination) // draw a straight line

Parameter 1: Start Coordinate

Parameter 2: terminal Coordinate

4. ccPointSize (GLfloat pointSize) // you can specify the size of each vertex.

5. ccDrawPoint (const CCPoint & point) // draw a point
