Question

opengl es同时绘制3d和2d图形

用opengl es做android游戏的开发，想在绘制3维图形的时候，同时完成2维图形的绘制（2维的图形主要是画面上的菜单或是按钮）该怎么弄呢？望兄弟姐妹们帮帮忙

Answer 1

glScissor(...);
glEnable(GL_SCISSOR_TEST);

 这是可以实现局部绘制的函数，自己百度

Answer 2

局部绘制，可以实现的。

思路是什么，有例子或是部分源码吗？谢谢啦

Answer 3

#1 way : create a 2D system including buttons and text on top of opengl es, maybe you will use some existing engine.

#2 way : use a surface view for 3D and a layout for 2D, layout has a transparent background, so it may look like combined. but usage is limited.
