Description

System and method for making and playing real-time 3D movie/game based on role playing

The present invention relates to a 3D (3D) movie/game movie/game production and playback system and method, and more particularly to a role-playing real-time 3D movie/game system and method, particularly for more popular Production/play of personal 3D movies/games. Background technique

Role-playing refers to the user's first or third-person perspective, using a mouse and keyboard to enter a device to operate a virtual character to perform a character's performance in a 3D movie/game. Role-playing as a method of operating virtual characters is widely used in 3D computer games, especially in FPS (first-person shooter) and RPG (role-play) games.

A conventional 3D movie refers to a non-real-time movie, which typically outputs a compressed still image sequence file through long-time rendering, and then views by decompressing and playing a sequence of still images. The traditional 3D movie production process is as follows: separately create independent 3D scenes, models, characters, and actions; in the online block diagram mode, add 3D models, characters and animations to the scene from the camera's perspective; after long-time rendering, output Effect diagram or graph 'sequence; According to the rendered effect graph or graph sequence, return to the wireframe mode, adjust the original scene, and then output the effect graph or graph sequence again, and then repeat until a satisfactory effect graph or graph sequence is obtained. For the production of traditional 3D movie clips, you can refer to the famous 3D movie production software such as Autodesk 3dsmax and Maya.

The production of traditional 3D games is generally divided into a production development environment (game editor) and a game running environment. The production and development environment of the game is similar to the production environment of 3D movies. The production process is as follows: Create separate 3D scenes, models, characters, and actions; In the game editor, add 3D models to the scene from the perspective of the camera. Characters and animations; In the game editor, select the objects in the scene, in the properties window, change their properties; when the editing of the game is completed, switch to the game running environment, watch the effect, and so on, until you are satisfied with the correct Game experience. For the production of traditional 3D games, you can refer to the famous 3D game development software such as Unreal Engine.
