Or similar things. Is ScreenToWorldPoint a special reason why you do not want it?

In theory, you can compute and understand mathematics, but you will waste energy unless you have a special reason not to use ScreenToWorldPoint. Points in the world depend on various factors such as camera angle, position, projection. However, when using a fixed camera, it changes with the passage of time.

The camera maps world space to screen space. Render the project coordinates of the world space as a screen in a two-dimensional plane. Therefore, if you want to convert the position of the world to the position of the screen (and vice versa), you need to use the camera. The camera has a setting that determines the projection method of coordinates. These settings basically determine the size of the world space unit in the screen space. If you are using a 2D camera (ie orthographic), the camera's orthorectification will determine the visible size of the camera. If set to half the height of the screen, one pixel will be fully mapped to one unit. To calculate the position of the world, it is simple camera.position + ((screen space position - center of screen) / screen height / 2 * orthogonal size). For example, if (0, 0, 0) + ((400, 400) - (400, 300) and (400, 400) and the resolution of the camera are 0, 0, 0, the resolution of the screen is 800, 600 and the size of the orthophoto is 10, )) / (It becomes 800/2) * 10) = (0,0,0) + ((0,100) / 400 * 10) = (0,0,0) + (0,2.5)

As of March 31, 2015, 38,719 screens in the United States (total of 39,789 screens) are converted to numbers (of which 15,643 screens are 3D compatible) and 3,007 screens in Canada (1,382 screens are 3D) are converted internationally. 93, 147 screens (59, 350 are 3D). Congratulations, exhibitors, almost done! However, in the United States and Canada, we made major progress, but in some international regions it is still related to digital conversion.

Canada is the first country in the world to operate a dual screen movie theater. In 1957 when Canadian theater owner Nat Taylor transformed two movies into a theater where you can play two movies at the same time, Elgin Theater in Ottawa, Ontario became the first venue to screen two movies on different screens. Taylor was invented by a Canadian source as a multiplexor or film inventor; he later founded the Cineplex Odeon, which opened the world's largest multi-screen Eton Center movie to Toronto, Ontario. In the United States, in 1963 Stanley Durwood of American Multi-Functional Film Company (now AMC Cinema) carefully manages the start time of each person and can manage several additional auditoriums by requiring the same staff I approved. It is a pioneer of diversity. It is a movie. The Ward Parkway Center in Kansas City, Missouri is screening the first multiplex movie in the United States.
