Detailed description of the invention
Invention is described further using attached drawing, but the embodiments in the accompanying drawings do not constitute any limitation to the present invention,
For those of ordinary skill in the art, without creative efforts, it can also be obtained according to the following drawings
Its attached drawing.
Fig. 1 is the flow chart of the invention based on BIM technology high emulation plant production method.
Specific embodiment
The invention will be further described with the following Examples.
The present embodiment based on BIM technology high emulation plant production method, include the following steps:
Step 1: the threedimensional model component of plant is generated in SpeedTree software；
Step 2: the threedimensional model component is saved as into Fbx format；
Step 3: the threedimensional model component of Fbx format is imported into 3dmax software；
Step 4: material editor is carried out to the threedimensional model component in 3dmax and tree-like and color adjusts；
Step 5: the threedimensional model component of step 4 is exported into Fbx format.
Preferably, the step 1 includes following sub-step:
Sub-step A: opening SpeedTree software, selects File-New, creates a file, the operation of viewport is: middle key is flat
It moves, left button rotation, right button recalls menu；
Sub-step B: increase node using the node type editing machine of SpeedTree, right button, which clicks Tree node, will pop up increase section
The option of point:
Branches: branch,
Fronds: branch (with blade),
Hand Drawn: Freehandhand-drawing,
Leaves: blade,
Roots: tree root,
Trunks: trunk,
From file: some mesh, such as stone etc. are imported from file.
Sub-step C: selection Trunks-Standard.stt increases a trunk for it, can be appreciated that in viewport more one
The grey mould of a trunk, while the scale for also measuring its height and object of reference (people) occurred；
Sub-step D: the parameter if necessary to adjust trunk needs to select the model of trunk in viewport or in node editing machine
Middle selection Trunck node, at this time the parameter menu on the left side just will appear the corresponding parameter of trunk.
The height (the not radius of influence) of the adjustable trunk of Length
Start angle: the angle of arboreal growth keeps litter that can aim in center long above here.
Perturbance: this is whether controlling trunk rule, if do not chosen, trunk will grow more regular.
It preferably,, need to be with the prong numbers of Bifuracation adjustment trunk after increasing trunk in the sub-step C
Simple mode is changed to Complete mode in Properties, into Complete mode and then opening
The prong length of trunk is adjusted in Bifuracation volumes of exhibition column, simple mode is then switched back into, in Branch volumes of exhibition
The radius of trunk is adjusted below column, radius can be adjusted 2.5.Left break spot and Right break spot may be used
To be transferred to maximum (seeming seem the appearance for being broken off half in this way), the value for then adjusting Spot falls bifurcation
In place.
Preferably, sub-step E is executed after sub-step D: production plants ' aesthetics organ: collecting the sample of plant to be produced,
The topological structure and geological information of its structural characteristic parameter, limb system are analyzed, the ornamental organs such as acquisition leafage, flower, fruit, stem
Texture picture handles organ texture, generates the organ texture or common texture with the channel Alpha.
Preferably, to the bark with hackly surface characteristics, Yao Shengcheng normal direction texture.
Preferably, the adjustment in the step 4, including tree-like and color adjustment.
In step 4, material shows translucent after the threedimensional model component of Fbx format is imported into 3dmax software,
The reason is that the textures problem of transparent channel.Conventional solution is that irreflexive figure is replicated a node, by it
It is set as using transparent channel.Specifically it is provided that
1, it is first turned on (the patch that the format after SpeedTree Compiler compiling is srt and dds of the spm file in treebank
Figure), export mesh.
2, the Export Option is arranged: export material and textures, if you do not need to animation, bone can not be exported.
3, it is imported in 3dmax, draws material and check, it can be seen that be that transparent channel goes wrong.
4, it after modifying material node, can normally show.
5, finally, can also export if it is large quantities of duplications are needed as vray proxy object.
And the present embodiment passes through the material script (can find under the installation directory of sp) of operation SpeedTree, problem
It all solves quickly, it is convenient and efficient.
Material editor is carried out to the threedimensional model component in 3dmax and tree-like and color adjusts, more convenient operation is quick,
Also ensure that the threedimensional model component imported into lumion software and can't go wrong.
It further include computer storage medium based on BIM technology high emulation plant manufacturing system, including processor, the meter
For calculation machine storage medium for storing computer program, which realizes above-described be based on when being called by processor
