将OpenGL glBegin（）移植到OpenGL ES

问题描述

从普通OpenGL到以下序列如何转换为OpenGL ES？

    displayList = glGenLists(1);
    glNewList(displayList, GL_COMPILE);

    glBegin(GL_TRIANGLES);
        glNormal3f(n1.x, n1.y, n1.z);
        glVertex3f(v1.x, v1.y, v1.z);
        glNormal3f(n2.x, n2.y, n2.z);
        glVertex3f(v2.x, v2.y, v2.z);
        glNormal3f(n3.x, n3.y, n3.z);
        glVertex3f(v3.x, v3.y, v3.z);
    }
    glEnd();

    glEndList();
    glCallList(displayList);
