OpenGL 放置平面
我正在尝试创建一个 SurfaceView，其中包含一个显示 9 个平面的 GLView。 我试图让平面围绕原点以菱形定向。本质上，顶层全部以 120 度角指向原点，以圆形分隔 120 度。中间层也将分开 120 度，但垂直于 x 轴并平行于 y 轴。底层将是顶层的反转。
到目前为止，我已经尝试过循环（没有很好地结束，飞机分散在创造物中）并逐个飞机地进行，以确保偏航和俯仰设置正确。两者都没有起作用。
如果您有任何想法，请告诉我或为我指出一个像样的教程的方向。
谢谢 ~Aedon
这是我的逐行代码片段：
dyaw & dpitch: 120 度
w & h：宽度（2）和高度（3）相应
间距：.5f
// Top Layer
mGL.glRotatef(dyaw, 0, 1f, 0);
mGL.glRotatef(dpitch, 0, 0, 1f);
mGL.glTranslatef(0, h + spacing, 0);
mPanels[0].drawColorful(mGL);
mGL.glRotatef(dyaw, 0, 1f, 0);
mPanels[1].drawColorful(mGL);
mGL.glRotatef(dyaw, 0, 1f, 0);
mPanels[2].drawColorful(mGL);
// Middle Layer
mGL.glRotatef(dyaw, 0, 1f, 0);
mGL.glRotatef(-dpitch, 0, 0, 1f);
mGL.glTranslatef(0, -(h + spacing), 0);
mPanels[3].drawColorful(mGL);
mGL.glRotatef(dyaw, 0, 1f, 0);
mPanels[4].drawColorful(mGL);
mGL.glRotatef(dyaw, 0, 1f, 0);
mPanels[5].drawColorful(mGL);
// Bottom Layer
mGL.glRotatef(dyaw, 0, 1f, 0);
mGL.glRotatef(-dpitch, 0, 0, 1f);
mGL.glTranslatef(0, -(h + spacing), 0);
mPanels[6].drawColorful(mGL);
mGL.glRotatef(dyaw, 0, 1f, 0);
mPanels[7].drawColorful(mGL);
mGL.glRotatef(dyaw, 0, 1f, 0);
mPanels[8].drawColorful(mGL);
I'm trying to create a SurfaceView that contains a GLView showing 9 planes.
I'm trying to get planes oriented in a diamond shape around the origin. Essentially it will have the top layer all point in towards the origin at a 120 degree angle separated in a circular shape by 120 degrees. The middle layer will also be separated by 120 degrees but be perpendicular to the x axis and parallel to the y. The bottom layer will be an inverse of the top layer.
So far I have tried loops (didn't end well, the planes were scattered across creation) and going by plane by plane to make sure that the yaw and pitch were properly set. Neither have worked.
If you have any ideas please tell me or point me in the direction of a decent tutorial.
Thanks

Here is my line by line code snippet:
dyaw & dpitch: 120 degrees
w & h: width(2) and height(3) accordingly
spacing: .5f
// Top Layer
mGL.glRotatef(dyaw, 0, 1f, 0);
mGL.glRotatef(dpitch, 0, 0, 1f);
mGL.glTranslatef(0, h + spacing, 0);
mPanels[0].drawColorful(mGL);
mGL.glRotatef(dyaw, 0, 1f, 0);
mPanels[1].drawColorful(mGL);
mGL.glRotatef(dyaw, 0, 1f, 0);
mPanels[2].drawColorful(mGL);
// Middle Layer
mGL.glRotatef(dyaw, 0, 1f, 0);
mGL.glRotatef(-dpitch, 0, 0, 1f);
mGL.glTranslatef(0, -(h + spacing), 0);
mPanels[3].drawColorful(mGL);
mGL.glRotatef(dyaw, 0, 1f, 0);
mPanels[4].drawColorful(mGL);
mGL.glRotatef(dyaw, 0, 1f, 0);
mPanels[5].drawColorful(mGL);
// Bottom Layer
mGL.glRotatef(dyaw, 0, 1f, 0);
mGL.glRotatef(-dpitch, 0, 0, 1f);
mGL.glTranslatef(0, -(h + spacing), 0);
mPanels[6].drawColorful(mGL);
mGL.glRotatef(dyaw, 0, 1f, 0);
mPanels[7].drawColorful(mGL);
mGL.glRotatef(dyaw, 0, 1f, 0);
mPanels[8].drawColorful(mGL);

没关系，来自 INsanity 找到了更好的教程。如果有人对 Android 有任何 OpenGL 问题，请尝试一下这些人的教程，他们非常棒。

Never mind, found a much better tutorial from INsanity. If anyone has any OpenGL question for android take a stab with this guys tutorials, they are fantastic.
