1世界空间
原文:
Think of it as transforming a house by scaling it down (it was a bit too large in local space), translating it to a suburbia town and rotating it a bit to the left on the y-axis so that it neatly fits with the neighboring houses.

翻译:
你可以想象一下,我们需要转换一栋房子,通过将它缩小(因为它在局部坐标系中显得太大了),将它往郊区的方向平移,然后沿着y轴往坐标旋转。

ps:最后一句,应为“然后沿着y轴往左旋转”

2透视投影
原文:
anything outside the frustum will not end up in the clip space volume and will thus become clipped.

翻译:
任何在这个平截头体的对象最后都不会出现在裁剪空间体积内,并且将会受到裁剪。

ps:应为“任何在这个平截头体的对象...”

3透视投影
原文:
The second parameter sets the aspect ratio which is calculated by dividing the viewport's width by its height.

翻译:
第二个参数设置了宽高比,由视口的高除以宽

ps:看原文是高/宽,但上面公式是宽/高,感觉公式应该更准确

4进入3D
翻译:
我们会通过将场景沿着z轴正方向平移来实现这个

ps:应为“我们会通过将场景沿着z轴方向平移来实现这个”

5.进入3D
翻译:
OpenGL会将它的深度值和z缓冲进行比较然后如果当前的片段在其它片段之后它将会被丢弃,然后重写

ps:最后应为“否则重写”
