我正在尝试填充由4行生成的四边形GL_LINES.但是,当我尝试填充四边形时,它只填充三角形.这是绘制线条的代码:

def SurfaceContour(self, vertices, edges):
     glBegin(GL_LINES)
     for edge in edges:
         for vertex in edge:
             glColor3fv((1.0, 0.0, 0.0))
             glVertex3fv(vertices[vertex])
     glEnd()

这是绘制填充四边形的代码:

def Surfaces(self,  vertices):
     glBegin(GL_QUADS)
     for i in range(4):
        glColor4f(1, 1, 1, 0.3)
        glVertex3fv(vertices[i ,:])
     glEnd()

这是我传入的顶点矩阵:

[[   0.    -20.23    7.  ]
 [   0.    -20.23   -7.  ]
 [ 100.    -10.      5.  ]
 [ 100.    -10.     -5.  ]]
