Problems solved by technology

However, while MultiGen Creator provides a powerful interactive modeling function, it lacks a convenient and complete programming interface, so that the user's own program can be inserted into any position in it, so as to realize the automation of the modeling process; at the same time, MultiGen Creator Has a high price, making it prohibitive for ordinary users

Abstract

The invention is a 3D modeling-oriented man-machine interactive frame, comprising hardware layer, 2D event layer, 3D event layer, interactive layer and display layer from the bottom up; the hardware layer is composed of interactive devices; the 2D event layer is used to catch the interaction from the operator and convert it into 2D interactive information; the 3D event layer selectively converts the 2D interactive information into 3D interactive information; the interactive layer is divided into 2D interactive layer and 3D interactive layer, where the former receives the 2D interactive information to produce corresponding 2D interactive task and the latter receives the 3D interactive information to produce corresponding 3D interactive task; the display layer completes the interactive operation according to the 2D and 3D interactive tasks and feeds the effect to the user. The invention support the standard Open Flight-format model database files, providing various functions of browsing, model building, model modifying, etc, and the whole system has a user-friendly visual graphic interface, able to make high efficiency 3D model edition and has low price.

Description

technical field [0001] The invention relates to a three-dimensional modeling tool, in particular to a human-computer interaction framework oriented to three-dimensional modeling. Background technique [0002] The main function of the 3D modeling tool is to display the 3D scene and communicate the 3D model to interact with the user. At present, the 3D modeling tool is mainly the 3D modeling tool MultiGen Creator of Computer Associates (CA) in the United States. It is a software for virtual real-time systems and has many functions dedicated to building models for real-time rendering. Among them, LOD It is possible to make the model away from the viewpoint by using a low-resolution display, and Switch can produce deformation, damage effects, etc. in the interactive environment. In addition, MultiGenCreator also has statistics and reporting functions about the number of model triangles, number of textures, occupied memory and rendering speed, etc. These functions also provide a...
