In the science fiction movie, the real animation special effect is used extensively, I believe everybody to "Jurassic Park" the movie the Dinosaur and the reality "the performance" the picture to leave the deep impression. In fact, these are through the camera tracking technology will be animated modeling and real combination. Similar functionality is also seen in 3D Studio Max, which combines a real-world desktop with a three-dimensional rhino, allowing a cute little rhinoceros to wobble on our desks.
There's a lot of animation and real-life stunts in sci-fi movies.
Creative thinking: The camera tracking function may easily capture the camera motion trajectory, so that the virtual camera can realistically "place" in the real scene.
The Camera matching tool uses a bitmap background photo and five or more special "Campoint" objects to create or modify the camera so that its position, direction, and view match those of the camera that created the original photo.
You must accurately measure the distance of at least five photographic points in the scene, and these functions are not all located on a plane.
Production steps:
1. Set up 6 photography points in real scene
First of all, on the table and on the calendar to determine 6 red dots as a photographic point, the size shown in Figure 1.
It must be mentioned that at 3D Max the photographic point must be more than 5 and not all located on a plane. It is best to use the points that are distributed throughout the scene without using the functionality of all the clusters in front or behind, which will result in more precise results. In this case, the placement and measurement of photographic points are not accurate, only for demonstration purposes, so the final effect is not ideal. Using more precise photography points may result in a more perfect effect.
Figure 1 determine 6 trace points in the scene
For the actual shot, this example uses a digital camera, attention, no matter how the camera movement, 6 red photography points must be in the picture, indispensable.
