Embodiment 1
A kind of implementation method that the present invention describes based on the three-dimensional information in three-dimensional scene presentation file, with windows XP operating system is working environment, based on ogre real-time graph render engine, adopt following framework, this method comprises that 8 system synergistic workings finish, be respectively three-dimensional picture render engine, three-dimensional lantern slide and generate system, the scene template base system of being provided with, object storehouse system, the annexation disposal system, rareness texture processing system, literal input editing system and three-dimensional demonstration document content form interface.As shown in Figure 2, basic realization flow of the present invention may further comprise the steps:
A) start three-dimensional picture render engine loading scenario template base, real-time rendering is also carried out in the object storehouse;
B) use cone scene scalping method to quicken real-time rendering efficient based on radar method;
C) by three-dimensional lantern slide generation system is set the three-dimensional demonstration document is set;
D) in three-dimensional lantern slide, carry out the literal input editing by the literal input editing system;
E) carrying out the literal sharpening by rare texture classes disposal system handles;
F) start presentation file lantern slide annexation system, three-dimensional lantern slide is connected into the three-dimensional demonstration document;
G) by three-dimensional demonstration document content form interface the three-dimensional demonstration document content is preserved into specific format.
Step a. starts three-dimensional picture render engine loading classes and is similar to two-dimentional presentation file manufacturing system interior template base and object storehouse, form template base with the real scene of three dimensional stress in the present invention, the object storehouse is similar to " clip art " storehouse in the two-dimentional presentation file manufacturing system, realize with the true model bank of three dimensional stress among the present invention, then and carry out the real-time rendering of three-dimensional vision.
Carry out step b when carrying out step a and use the efficient cone scene rejecting algorithm based on radar method to quicken real-time rendering efficient, it is technology as well known to those skilled in the art that the efficient cone scene of described radar method is rejected algorithm.Radar method only need be known the visual angle, i.e. three parameters of the right line of vision amount of FOV angle, forward sight vector sum, and these three parameters are employed identical with video camera, can directly read from video camera.Because the realization of radar method need be used the tangent value of FOV angle, so need the FOV angle that reads out is converted into its tangent value.
Also can earlier the right line of vision amount of FOV angle, forward sight vector sum that reads out be cushioned preservation, when video camera changes the visual angle, calculate again then.If the visual angle remains unchanged, directly, just the cone can have been created from the right line of vision amount of video camera copy forward sight vector sum.
As shown in Figure 3, a some p, whether we want watching focus p in the cone, need try to achieve the coordinate of a p earlier, and equation is:
h＝pc.z*2*tan(FOV/2)，w＝h*ratio；
Judging point p whether 3 conditions in the cone is:
1.nearDistance＜pc.z＜fatDistance
2.-h/2＜pc.y or pc.y＞h/2
3.-w/2＜pc.x or pc.x＞/h/2
The coordinate of trying to achieve a p is then put p in the cone as satisfying above-mentioned 3 conditions; Otherwise, then do not exist.
Step c uses the bulletin board technology to realize default three-dimensional lantern slide.Because in three dimensions, there be positive and negative, front and back, the upper and lower relation on the direction in the object of structure, and in order to follow people use lantern slide in two-dimensional space custom, the present invention has adopted three-dimensional bulletin board technology to be made into three-dimensional lantern slide in three-dimensional scenic.As shown in Figure 4, in three dimensions, the front that makes three-dimensional lantern slide so also makes word content can not go to the back side all the time in the face of the operating personnel before the display to the bulletin board technology with the flat pannel display of two dimension.
Steps d. in three-dimensional lantern slide, carry out the literal input editing by the literal input editing system; When carrying out steps d, promptly in three-dimensional lantern slide during input characters, step e also brings into operation, and divides texture mapping technology by anti-aliasing thresholding the literal in the lantern slide (in three dimensions, literal belongs to the rare texture classes of color) is carried out texture update and output.
It is first the picture that has existed that anti-aliasing thresholding is divided texture mapping technology, uses thresholding two-wire shape interpolation to obtain new optimization texture, and these textures are to be made of discontinuous polygon line, and it is the description to whole texture.Doing when dwindling the playing up of amplification, use thresholding to divide texture algorithm, fast updating texture.General picture can produce sawtooth when amplifying or dwindling, if directly use anti-aliasing algorithm, can produce the blur effect of periphery.Anti-aliasing thresholding is divided texture mapping technology and can well treated texture be dwindled arbitrarily or amplify, and can not reduce picture clarity.This algorithm does not need to consume very much video card capabilities yet, plays up the influence that speed can not be calculated.Utilize this technology, current video card can reach the speed that per second is filled 1,000,000,000 pixels.As shown in Figure 5, when being convergent-divergent, first uses general anti-aliasing design sketch, the design sketch during second convergent-divergent when being to use anti-aliasing thresholding to divide texture mapping technology, and the 3rd is original graph.Described thresholding is divided the texture algorithm and general anti-aliasing algorithm is technology as well known to those skilled in the art.
Step f. has realized following linkage function by technology such as the Portal scene handoff technique in the three dimensions, 3D trigger technology, the smart technology of guiding and Lua scripts in three dimensions, thereby each three-dimensional lantern slide is connected into the three-dimensional demonstration document:
(1) next is opened/last lantern slide, first/last lantern slide, the last demonstration, ends the control redirect action of general lantern slides such as showing;
(2) user definition shows: the broadcast order that the deviser sets;
(3) lantern slide (slide): the redirect action that sets between the lantern slide in the same presentation file.
In order to realize the annexation of three-dimensional lantern slide in three-dimensional scenic, the present invention has adopted the Portal scene handoff technique in the three dimensions, 3D trigger technology, the smart technology of guiding and Lua script to realize above-mentioned linkage function.
A) in three dimensions, adopt three-dimensional scene Portal technology to finish the switching of three-dimensional lantern slide and 3d space scene simultaneously.3d portal technology is the technology of being checked another scenario B under a scenario A by portal (inlet).When we need switch lantern slide and scene simultaneously, only need mobile camera, make video camera enter the another side of portal, just realized the task of handoff scenario and lantern slide.In the process of scene and lantern slide switching, do not need to reload scene or load new scene, scene is switched very smooth, very natural.Portal technology and video camera move and can give expression to the sense of reality effect of advancing, retreating easily.
B) the three dimensions trigger only switches three-dimensional lantern slide in Same Scene.When mouse or KeyEvent have triggered trigger, trigger will call corresponding disposal route, in order to switch different lantern slides.
C) the guiding spirit is to be used to strengthen the new model that annexation replaces arrow, makes role or dynamic 3D form have more the attractive force effect.Guide smart body the track route need be set, the track that promptly connects between the lantern slide is used to realize the connection between the three-dimensional lantern slide.The guiding spirit is to combine with trigger and the guide spirit that produces, mainly shows as 3d elfin or 2d elfin.The click guiding is smart, thereby has triggered trigger, and trigger calls corresponding disposal route, switches different lantern slides.The guiding spirit generally is translucent, can be forms such as picture, three-dimensional model, abstract three-dimensional symbol or three-dimensional animation model, conveniently produces gorgeous purpose effect, gives strong visual impact, stays deep impression.
D) carry out shell script: carry out by the designed shell script of LUA, the present invention adopts the mode of Lua script to realize the macroefficiency of three-dimensional lantern slide, realizes the various control function of three-dimensional scenic and mutual by one group of script function.
Step g. as shown in Figure 6, three-dimensional demonstration document content form interface adopts the classification compressed encoding and carries out the preservation of data in conjunction with scale-of-two XML form, at the XML of file tree type hierarchical structure for model data or texture mapping and lteral data difference compression method in different ways according to type, such as lteral data and model data are used non-distortion compression algorithm, compress and go on foot the interior distortion compression algorithm of losing former effect for data such as texture mapping, after the classification compression, and the XML tree type hierarchical structure of integral body also carried out binary conversion process, finally preserve into P3D (the suffix name based on the presentation file file in the three-dimensional scenic of the present invention's definition) form.Described non-distortion compression algorithm and distortion compression algorithm are technology as well known to those skilled in the art.
