Problems solved by technology

[0009] In view of the above problems, the purpose of the present invention is to provide a method for realizing a 3D information presentation document based on a 3D scene. This method overcomes the simple and dull effect of the existing 2D information presentation document, and at the same time solves the problem that the operation of the 3D editing system is very complicated. , ordinary people cannot easily produce 3D information presentation documents

Embodiment 1

[0038] A kind of realization method based on the three-dimensional information demonstration document in the three-dimensional scene that the present invention describes, take the windows XP operating system as the working environment, take the ogre real-time graphics rendering engine as the basis, adopt the following architecture, the method includes eight systems working together to complete , which are 3D graphics rendering engine, 3D slide generation setting system, scene template library system, object library system, connection relationship processing system, rare texture processing system, text input editing system and 3D presentation document content format interface. As shown in Figure 2, the basic implementation process of the present invention includes the following steps:

[0039] a) Start the 3D graphics rendering engine to load the scene template library and the object library and perform real-time rendering;

[0040] b) Using the radar-based frustum scene cullin...

Embodiment 2

[0070] The equipment and method used are basically the same as in Example 1, the only difference is that in step c, any object in the three-dimensional space is used as a slideshow to realize a single three-dimensional slideshow, only need to select the object and set it as a slideshow attribute, it can be realized to input text on it, directly as three-dimensional slide for three-dimensional object object, and display text on it, the present invention uses Multitexture (multiple texture technology) or Decal channel technology to realize.

[0071] Multi-texture technology refers to the technology that multiple textures can be mixed and displayed on the 3D object to improve the rendering effect. The present invention uses the text layer as a layer of texture in the multi-texture, and mixes and superimposes it on the original texture of the object.

[0072] 3D real-time rendering needs to deal with a lot of rendering passes, among which the Decal (printing) pass belongs to one of...

Abstract

The invention relates to the computer science and technology field, in particular to the method of 3D demo documents displayed in 3D scene. The basic flow of the invention comprises: starting 3D graph render engine to load the scenario template library, the object library and performing real-time rendering; accelerating the real-time rendering efficiency by using the cone scene scalping method based on radar path planner; setting up 3D demo documents through the 3D slide generation setting system; inputting and editing words in the 3D slide through the word input and edit system; sharpening the words through the scare texture process system; connecting the 3D slide into a 3D demo documents; saving the content of the 3D demo documents into a special format through the 3D demo documents content format interface. The method of the invention has the convenience of processing 2D domo documents as well as the effect of domo documents in the 3D scene, and improves the display, interaction and maneuverability of the traditional domo documents.

Description

technical field [0001] The invention relates to the technical field of computer science, in particular to a method for realizing a three-dimensional presentation document in a three-dimensional scene. Background technique [0002] With the rapid development of computer science, the explosive growth of information is driven. In this age of eyeball economy, whoever can attract eyeball attention in a unique way is the master of the information world. [0003] At present, in various information exchange and dissemination activities such as office work, conferences, teaching, and exhibitions, the most commonly used method is to play presentation documents. However, the current presentation documents are no different from those five years ago in terms of form and content. At present, The most commonly used presentation document production systems are mainly the MS PowerPoint system provided by Microsoft Corporation of the United States, and the WPS provided by Kingsoft Corporation...
