Embodiment Construction

[0018] A computer simulation method for generating fireworks of a specific shape: the user inputs a 3D model representing a specific shape or the index information of the 3D model on the client side, and the server side of the system uses inverse dynamics to simulate the shape-constrained fireworks, and generates the personality of the specific shape in real time. The generated personalized animation file can be sent to the user through e-mail or sent to the user's mobile phone through MMS.

[0019] For specific procedures, see figure 1 . The index information input by the user on the client can be a name (for example, "Zhang San"), birthday (for example, "October 1, 1990", specific text (for example, "I love you", "Happy birthday", "Merry Christmas", "HappyBirthday") or a 3D model file representing a specific shape (for example, OBJ format, 3DS format, PLY format, STL format, IGES format, WRL format, DXF format, etc.).

[0020] 1. If the number of vertices of the model in t...

Abstract

The invention discloses a computer cartoon simulation method by which individuated special-shape firework is created. A user inputs a three-dimensional model or index information of the three-dimensional model indicating a special shape at a client terminal, the system automatically creates a computer cartoon simulation process in which the firework is emitted, exploded to form the three-dimensional model shape designed by the user and finally disappeared. A generated individuation cartoon file can be sent to the user terminal via electronic mails or color messages. In the whole simulation process, an approximate inverse dynamic method is adopted, the air friction force and quality changes after firework burning are considered, in this way, the formation and fall of the firework are close to the real physical process. The invention provides an internet-based, cheap, individuated special-shape firework cartoon creating method, which is a new digital entertainment solution.

Description

technical field [0001] The invention relates to the technical field of digital simulation and transmission communication, in particular to a method for generating a personalized firework animation with a specific shape based on the Internet. Background technique [0002] Particle systems are an important part of computer animation technology, see William T. Reeves. "Particle Systems---A Technique for modeling a class of Fuzzy Objects." Computer Graphics, 17(3): 359-376. Some of the natural scenes, such as clouds, smoke, fog, water flow and flames, are difficult to achieve in conventional computer image synthesis methods. The reason for this is that these "fuzzy" objects do not have apparently smooth surfaces, but are irregular, complex, and difficult to describe. For these objects, the part we are interested in is the dynamic and fluid changes in general form and appearance. Particle systems provide a way to describe such "fuzzy" objects. [0003] The basic idea of ​​the ...
