Tutorial: film-files for showing a more complex film ==================================================== Example for a film showing a house with a smoking chimney, the moon, a tree, a cloud passing by darkening the picture when it covers the moon, and a running animal. To run this film, use tut-film1.c. The film is located in "film/film-3/" with name "film.film". How to organize the film At first we have to consider how many picture-files are needed. There are many possibilities between many picture-files and only a few of it which use many parameters. We want to use 8 pictures using 5 pictures-files (some are reused): First we will see the smoking house, the tree and moon, a music is starting -> first picture-file. Next the cloud is coming from left up to the middle of the picture -> second picture-file. While the cloud is going on, an animal is running from right to left -> third picture-file. The animal has gone, the cloud moves on until it reaches the moon -> second picture-file again with other parameters. While the cloud is covering the moon, it becomes darker -> forth picture-file. The cloud covers the moon, an owl is crying -> fifth picture-file. While the cloud is decovering the moon, it becomes brighter -> forth picture-file again with other parameters. The cloud moves on until it leaves the picture -> second picture-file again with other parameters. film.film In this main film-file we load the 8 pictures. For some additional descriptions please refer to film/film-3/film.film ==>
