Example Embodiment

[0009] 1. First, determine the top view angle of the camera for viewing the 2.5D virtual character as required.

[0010] 2. According to the top view angle of the camera and the basic requirements of the virtual character model, design and determine a certain size ratio between the head, body, arms, and legs to ensure that the arms and legs are not blocked when the body moves head.

[0011] 3. Use 3D software (such as Maya or 3DMax) to create 3D models, actions, UV maps and materials of each part of the character according to the set size ratio between the head, body, arms, and legs, and save them.

[0012] 4. In the process of dressing up the characters, read in the 3D models, actions, UV maps and materials of each part, and use 3D graphics geometry calculations (without 3D hardware acceleration) to render according to the set top view angle of the camera. Render and output pictures with various expressions on the head and pictures with various actions on the body respectively.

Abstract

The invention relates to a technology for revealing actions and expressions of 2.5D (2.5 Dimensional) virtual characters, belonging to the field of a virtual character technology in a computer-software cartoon industry. At present, in 2D game engines, no technology not only can let users change the clothes of the 2.5D virtual characters, but also provide the actions and the facial expressions of the characters changed with clothes. The technical scheme of the technology comprises the following steps of: setting the certain size proportions among head parts, body parts, arm parts and leg parts according to application requirements; when changing the clothes, immediately carrying out 3D rendering and outputting 2D pictures by adopting subparts; and when in use, revealing the actions and the facial expressions of the 2.5D virtual characters (including animals) and characters by adopting a real-time 2D picture synthesizing method. By adopting the technology, common servers and clients can let the users arbitrarily change the clothes and also provide the actions and the facial expressions of the characters changed with clothes. The technology can be widely applied to the current software cartoon industry products comprising webpage games, Flash games, 2.5D virtual worlds and the like.

Description

technical field [0001] 2.5D virtual characters (including animals) and their movements and facial expressions are displayed through flat graphics or flat animation synthesis. It can be used in but not limited to virtual worlds, games, online games and other fields. Background technique [0002] A 2.5D virtual character refers to a character model that is not rendered by a 3D model, but has multiple perspectives, and when displayed on a display screen, it gives people a three-dimensional feeling. Because 3D technology has high requirements on graphics cards, 2.5D avatars are widely used in today's 2D games, Flash web games, and virtual worlds. But also because of the lack of 3D technology support, there is no such technology or product at present, so that 2.5D virtual characters can not only allow the general public to change their clothes at will, but also provide the actions and facial expressions of the changed characters. Because, if a person has 10 actions, 3 frames fo...
