OpenGL 玻璃 HUD？
你好，我想知道如何制作看起来像“玻璃”的东西，例如皮克敏游戏中的例子。
它在 HUD 中，我想知道如何创建类似的东西。 我并不是想复制游戏，我只是喜欢它的外观。
它看起来像这样： http://3. bp.blogspot.com/_CWor6UdXxBk/SbaZDWSF6VI/AAAAAAAAFCU/UQgBvgGq-VE/s400/pikmin.jpg
其中有数字的矩形
我知道如何创建 HUD 但是我想知道如何动态生成背景矩形如示例中所示

您应该研究 alpha 混合来绘制气泡。假设它们的反射是静态的，您所需要的只是一个简单的图像。 （如果您不确定图像应该是什么样子，请看一下游戏中的黑墙。您看到的白色部分应该是图像的红色、绿色、蓝色和 Alpha 通道的样子。）
数字是只是绘制在气泡顶部（或下方）的另一组 alpha 混合图像。上述内容也适用于他们。
You should look into alpha blending for drawing the bubbles. Assuming the reflections on them are static, all you need is a simple image. (If you aren't sure what the image should be like, look at a black wall in the game. The white parts you see should be what the red, green, blue AND alpha channels of the image look like.)
The numbers are just another set of alpha-blended images drawn on top (or below) the bubbles. The above goes for them too.
看起来它们只是带有 Alpha 混合的纹理。一个矩形，一个圆形，然后绘制并缩放为适合其中任何内容的多边形。
It looks like they're just textures with alpha blending. One rectangular, one circular and then drawn and scaled to a polygon that fits whatever goes in them.
