OpenGL code to draw an object

public virtual bool SupportOpenGLPrimitives(IvdOpenGLRender openglrender)
{
return true;
}
public virtual void OnDrawOpenGLPrimitives(IvdOpenGLRender openglrender)
{
gPoints pts = this.BoundingBox.TogPoints();
openglrender.SetColor(System.Drawing.Color.FromArgb(100, 255, 0, 0));
openglrender.DrawPrimitiveBegin(VectorDraw.Render.OpenGL.OpenGLImports.Primitives.GL_POLYGON);
foreach (gPoint item in pts)
{
openglrender.Vertex3d(item.x, item.y, this.BoundingBox.Min.z);
}
