Problems solved by technology

[0004] Because in the production of scene files, only objects within the effective shooting range of the camera can be rendered and generated. Therefore, the objects in the scene file are only valid if they are included in the effective shooting range of the camera. Objects outside the range are invalid for the film

Embodiment

[0092] See Figure 4 , Figure 5 According to a method for compressing animation scene files of the present invention, a three-dimensional scene is compressed for a specific shot. Figure 4 It is an uncompressed 3D scene, containing 1,316,223 patches in total, and the scene file size is 148M; Figure 5 The compressed 3D scene contains a total of 100780 patches, the scene file size is 11M, and the compression ratio is 7%. From the comparison of the two images, the 3D scene after using this method can fully guarantee the high-quality rendering effect.

Abstract

The invention discloses a method for compressing animation scene files. During a progress when three-dimensional animation scenes are made by using maya, the finally generated scenes usually comprise a large number of useless historical nodes due to repeatability of a production cycle and uneven ability of production staffs, as a result, scene files are so large that the scenes are very inconvenient to store and use. According to the method for compressing animation scene files disclosed by the invention, by calculating a projection range of a scene camera, models which are not in the projection range can be deleted on a basis that necessary models and animation curves for the scene are kept, so that the size of the scene files can be compressed greatly.

Description

Technical field [0001] The invention belongs to the field of computer animation, and relates to application technologies such as computing projection geometry. Aiming at the problem of large capacity of scene files produced by Maya, a method for compressing animation scene files is proposed. Background technique [0002] During the 3D animation production process, it is necessary to frequently open, operate and save scene files. Due to the repetitiveness of the animation cycle and the variability of the abilities of the production staff, the final generated scene usually contains a large number of useless historical nodes, which causes the scene file to be too large and brings great inconvenience to the preservation and use of the scene. [0003] The traditional method of compressing scene files is mainly by clearing historical nodes in the scene and independent nodes in the hypergraph (not connected to any other nodes), but according to this method to compress the scene, the compr...
