With OpenGL, you can specify lines with different widths and lines that are stippled in various ways - dotted, dashed, drawn with alternating dots and dashes, and so on. Wide Lines void glLineWidth(GLfloat width); Sets the width in pixels for rendered lines; width must be greater than 0.0 and by default is 1.0.
