Detailed description of the invention
Below in conjunction with specific embodiment, the present invention is described in detail.Following example will assist in the technology of this area
Personnel are further appreciated by the present invention, but limit the present invention the most in any form.It should be pointed out that, the ordinary skill to this area
For personnel, without departing from the inventive concept of the premise, it is also possible to make some changes and improvements.These broadly fall into the present invention
Protection domain.
Optimization method is rendered in mobile terminal according to a kind of based on BIM ultra-large scene that the present invention provides, including:
Component information obtaining step: obtain the message file of multiple component；
Component generation step: the message file of multiple components is imported in d engine, obtains multiple component；
Component combining step: the plurality of component is merged into several components, is designated as merging rear part；
Component information updates step: generate the message file merging rear part；
Colouring switch process: the message file of described merging rear part is imported in d engine and paint and be converted into
Model.
Further, in component combining step, the plurality of component is merged into a component.
Further, in component combining step, the plurality of component is merged into multiple component.
Further, in component information updates step, the message file of described merging rear part includes coming from institute
State information relevant to described merging rear part in the message file of multiple component.
Further, also include:
Show response of step: only show in showing interface and merge rear part, and respond the operation being combined rear part.
Specifically, the present invention includes: derive the overall FBX file message file as component of Revit model；By FBX
Import to, in 3D Max engine, obtain each component；Merge all of component and become a component, and the structure merged is preserved
Return in FBX as the FBX file revised；The FBX revised is loaded in Unity3D engine and paints and be converted into BIM mould
Type.
Wherein, the message file of the plurality of component, may refer to the message file of a multiple component of correspondence, the most multiple
The Global Information file of component.When showing block mold, Unity3D engine is only loaded into the BIM model after merging.So due to
Only one of which component or the few merging rear part of quantity in the model being loaded into, translate, scale, the three-dimensional manipulating such as rotation time meter
Calculation amount will significantly reduce (as master mould has 10000 components, to be needed when the most often doing a three-dimensional manipulating to carry out 10000 times three
The calculating of dimension matrix change.After component merges, 10000 components are reduced to only 1 component, so calculation times is reduced to 1
Secondary, save the amount of calculation of 9999/10000).Simultaneously because being greatly decreased of the number of components, engine need not each component
Creating threedimensional model, save the redundant data of threedimensional model, therefore the internal memory shared by model also will greatly reduce.
Optimization system is rendered in mobile terminal according to a kind of based on BIM ultra-large scene that the present invention provides, including:
Component information acquisition device: obtain the message file of multiple component；
Component generating means: the message file of multiple components is imported in d engine, obtains multiple component；
