Using OpenGl to solve the transformation between screen coordinate and world coordinate;
利用OpenGL实现屏幕坐标与世界坐标的相互变换
For the complex traditional arithmetic that is difficult to be applied to practice, this paper presents arithmetic of the coordinates transformation from geodetic coordinates to plane rectangular coordinates and screen coordinates.
由此,给出实用的、可应用到系统中的完整的大地坐标到平面坐标以及平面坐标到屏幕坐标之间的正逆变换实现算法,尤其提出了基于简单迭代算法的大地坐标到平面坐标的逆变换公式,方便、精确地满足了电子海图应用系统的要求。
It provides the progress and implementation of how to get the real 3D object-point at the object reference frame from the 2D screen-point inputed by 2D point input device at the screen reference frame in a parallel perspective model.
提出一种“针刺取点”的三维拾取方法 ,介绍了在平行透视模型中 ,将二维点输入设备在屏幕坐标系下得到的二维屏幕坐标 ,反算成其在物体坐标系下真实的空间三维坐标的方法及其实现。
The viewing frustum has an origin(0,0) at the center of the screen, while screen coordinates have an origin at the upper left of the screen.
视图锥截体的原点(,0)屏幕中心，而屏幕坐标的则在屏幕的左上角。
The current screen coordinates are not valid. Make sure a valid number is entered for each screen coordinate, and then apply the new screen coordinates.
当前屏幕坐标无效。确保为每一屏幕坐标输入有效数字，然后应用新的屏幕坐标。
However, the executive summary is that you should bias your screen coordinates by -0.5 of a pixel in order to align properly with texels.
在执行的细节上，你需要注意把你的屏幕坐标向左偏移0.5以完成像素的对齐。
