opengl 如何转化成 opengl es 程序

各位看看，小弟谢了， 以下这段代码如何改写成opengl es 支持的程序啊。。。
-----------------------------------------------------------------------------------------
glBegin(GL_QUADS)

glColor4f(fAlpha, fAlpha, fAlpha, fAlpha)
glTexCoord2f(self.pTexture.fMinS, self.pTexture.fMaxT)
glVertex3f(-self.fWidth / 2.0, -self.fHeight / 2.0, 0.0)
glTexCoord2f(self.pTexture.fMinS, self.pTexture.fMinT)
glVertex3f(-self.fWidth / 2.0, self.fHeight / 2.0, 0.0)
glTexCoord2f(self.pTexture.fMaxS, self.pTexture.fMinT)
glVertex3f(self.fWidth / 2.0, self.fHeight / 2.0, 0.0)
glTexCoord2f(self.pTexture.fMaxS, self.pTexture.fMaxT)
glVertex3f(self.fWidth / 2.0, -self.fHeight / 2.0, 0.0)

glColor4f(fAlpha, fAlpha, fAlpha, 0.0)
glTexCoord2f(self.pTexture.fMinS, 0.65 * self.pTexture.fMaxT)
glVertex3f(-self.fWidth / 2.0,
-self.fHeight / 2.0 - fOffset + 0.65 * self.fHeight,
0.0)
glColor4f(fAlpha, fAlpha, fAlpha, 0.35 * fAlpha)
glTexCoord2f(self.pTexture.fMinS, self.pTexture.fMaxT)
glVertex3f(-self.fWidth / 2.0,
self.fHeight / 2.0 - fOffset,
0.0)
glColor4f(fAlpha, fAlpha, fAlpha, 0.35 * fAlpha)
glTexCoord2f(self.pTexture.fMaxS, self.pTexture.fMaxT)
glVertex3f(self.fWidth / 2.0,
self.fHeight / 2.0 - fOffset,
0.0)
glColor4f(fAlpha, fAlpha, fAlpha, 0.0)
glTexCoord2f(self.pTexture.fMaxS, 0.65 * self.pTexture.fMaxT)
glVertex3f(self.fWidth / 2.0,
-self.fHeight / 2.0 - fOffset + 0.65 * self.fHeight,
0.0)
glEnd()
