For making object of the present invention, technical scheme and advantage clearly, clearly, developing simultaneously referring to accompanying drawing, the present invention is described in more detail for embodiment.
Fig. 1 is the method flow of the implementation method of a kind of virtual three-dimensional glass breaking animation provided by the invention, and as shown in the figure, the step of the implementation method of described virtual three-dimensional glass breaking animation is as follows:
Step S1: utilize the solid images with crackle to obtain glass breaking data model;
Step S2: virtual impact object model;
Step S3: break process is carried out to the described glass breaking data model built;
Step S4: virtual broken animation.
Wherein, Fig. 2 is the method flow diagram of the step S1 of the implementation method of virtual three-dimensional glass breaking animation of the present invention, specifically comprises:
Step S11: introduce the image that has crackle data message, maps to the data message of crackle and needs to be broken in the virtual plane of calculating;
Step S12: the texture information catching the crack image of plane, and further mate setting with the texture information of the crack image of primary plane;
Step S13: treatment samples bar chart is as data further, namely adds the setting of the degree of depth in the data, becomes a parametric data model, and be set to the flat model with certain thickness.
Specifically, in step S11, first in three-dimensional software, introduce an image with crackle data message as shown in Figure 5, utilizing material edit routine to be mapped to by the data message of crackle needs to be broken in the virtual plane of calculating.
Preferably, the update routine of material edit routine and an image coordinate with the use of, the coordinate of crack image is applied to plane, can mate with plane, the crackle of crack image especially some details can be mapped out, and can also project to accurately in plane with its original size.
In step S12, based on the crack image of plane, utilize linear spline sequence of threads to catch the texture information of the crack image of plane, and further mate setting with the texture information of the crack image of primary plane.
Preferably, the design sketch that the procedure that adopts this to mate produces is as shown in the fragmentation simulation schematic diagram of glass model in the drafting design sketch of glass fragment model in the treatment of details schematic diagram of glass fragment model in Fig. 6 the present invention, Fig. 7 the present invention and Fig. 8 the present invention: mate successively according to the high-lighting size of crack structtire, first obviously outstanding texture information is mated, then refinement is carried out to texture structure, whole crack image is resolved into some fritters.When it should be noted that closed line transect for decomposing fritter, certain the one piece of data information overlap of the closed line transect that the data closing line transect all must be other with at least one.This matching process just can obtain the seizure data message of a crack image accurately, and the seizure data message of a crack image accurately could provide good optimized integration for program afterwards.
In step S13, by extruding the further treatment samples bar chart of update routine as data, namely adding the setting of the degree of depth in the data, becoming a parametric data model, and be set to the flat model with certain thickness, for the carrying out of subsequent step.
In step S2, the object model related in virtual three-dimensional glass breaking animation mainly contains impacting object, is knocked object and fixed object these three, and simultaneously the authenticity of animation is also mainly by the impact of the setting of these three objects and its mechanism each other.Wherein, impacting object: the source referring to the power allowing glass breaking produce, is generally the impact object with constant weight, and the whole structure of glass breaking is mainly impacted the impact of profile etc. of the speed of object, impact strength, quality, impacting body; Be knocked object: refer to and the object that impacting object is collided, this material, friction force, elastic force, fragment quality etc. being knocked object also determines final crushing effect; Fixed object: refer to that this book retains virgin state not by broken impact, but participate in the object of collision calculation, it is mainly used to affect broken effect, and it simulates profile, and object materials, elastic force and friction force etc. can change final crushing effect.Wherein, above-mentioned steps S1 is the manufacturing process of the break-up model being knocked object.
Wherein, the method of described virtual impact object model is specially: as shown in the impacting object modelling effect figure in Figure 10 the present embodiment, virtual impacting object is a Parametric geometric model, polygon edit routine is mainly utilized to carry out the structure of local data's information to it, change the data message such as node, line segment of model, thus fictionalize a new impacting object model.

Step S31: utilize breaker program to introduce thin glass sheet model in object module, be assigned therein as effect object;
Step S32: by broken module, fragmentation is carried out to effect object and calculate, obtain more fragment model;
Step S33: after the primary fragmentation of execution calculates, using primary broken results as effect object, perform fracture instructions again, perform the broken data processing of more refinement;
Step S34: carry out break process again to the broken data message in the local of crackle core, obtains more accurate broken results.
This step mainly utilizes the breaker program of three-dimensional program, carries out break process to the described pseudo-entity break-up model built in step sl.Wherein: first, in breaker program object module, local data's information fragment of described thin glass sheet is introduced, as participating in the broken effect object calculated.Then, after the primary fragmentation of execution calculates, breaker program using primary broken results as effect object, and then once can perform fracture instructions.Repeat same destruction step, after first fragmentation is carried out to each block thin glass sheet model, then perform the broken data processing of more refinement.By broken module, broken calculating is carried out repeatedly to effect object, obtain more fragment model; Because program itself has multiple different broken type, can by specifying different broken types for fragment in the process of fragmentation, to obtain different cataclasitlc structure.Destruction step described in same execution, carries out break process again to the broken data message in the local of crackle core, obtains more accurate broken results.
If expect the broken results of different broken type, cancel an order can be passed on to broken module by breaker program, then original result of calculation can be deleted by breaker program, after former broken module is backed up in the reduction of effect object, again send fracture instructions to effect object, the fragmentation carried out again calculates, and can obtain different cataclasitlc structure.
As shown in Figure 4, in the implementation method of virtual three-dimensional glass breaking animation of the present invention, the concrete grammar of step S4 is:
Step S41: described impacting object model is appointed as effect object, and the glass fragment that break process is good is appointed as fixed object; Described impacting object model can be cube model as shown in Figure 10;
Step S42: the physics engine in the breaker program described in utilization performs fracture instructions, forms complete animation.
This step is then the last process forming animation.
