Above-mentioned attribute information can include but is not limited at least one of：Vertex color (color), tangential data
(tangent) in, illumination pattern mapping coordinates.Fine arts personnel can be by above-mentioned first identifier during making 3D models offline
Information is recorded in attribute information.
Optionally, in step S14, according to the first of the second identifier information of partial model to be concealed and each vertex
Can also include step performed below before identification information determines multiple vertex corresponding with partial model to be concealed：
Step S13 receives the notification message for coming from Correspondent Node in the render process of threedimensional model to be rendered,
Wherein, second identifier information is carried in notification message.
In view of will be responsible for processing by the graphics processor (GPU) in computer equipment in 3D model renderings to screen
's.Therefore, if it is desired to it realizes that the part (position) of 3D models hides, then needs to operate in central processing unit (CPU), i.e., it is above-mentioned
Correspondent Node, on program will need identification information (the i.e. above-mentioned second identifier information) notice of hiding part (position) model
To GPU.
The process for rendering 3D models is that static immutable 3D model datas are transferred to GPU by CPU, then again by GPU
The process that the data received are handled.In the process, a most important step is that CPU exists the 3D models
The information such as position, direction in world space are notified to GPU.For this purpose, in this step, it can be by new in an announcement message
Increase and indicates which part of the model needs hiding related data.Such as：CPU notices GPU needs to hide the X office of the 3D models
Portion (position) model.Meanwhile in the grid data of model being that each part (position) model is numbered, thus it can allow
GPU can find the vertex of the corresponding all 3D models of corresponding X part (position) model, then as early as possible when rendering
It is hidden.Specific Stealth Modus used by GPU is not specifically limited herein, such as：GPU can be by X part (portion
Position) transparencies on vertex of the corresponding all 3D models of model is set as 0.
Optionally, in step S14, according to the of the second identifier information of partial model to be concealed and each vertex
One identification information determines that multiple vertex corresponding with partial model to be concealed may include step performed below：
The first identifier information on each vertex is compared with second identifier information by step S141 respectively, is obtained exclusive
In the vertex of partial model to be concealed；
The vertex for being specific to partial model to be concealed is determined as corresponding with partial model to be concealed by step S142
Multiple vertex.
During designing 3D models, in order to enable GPU can be searched when rendering by above-mentioned second identifier information
To specific portion (position) model of model, logic partitioning processing can be executed.3D models are specifically subjected to piecemeal, and at it
Record identification information in vertex attribute.Such as：One enclosure wall being made of four sides wall is logically segmented into four pieces (i.e. often
Face wall is one piece), then in each vertex attribute of every face wall, record identification information.Specifically, the first face wall record identification
1 (it is 0001 that it, which is converted to tetrad), the second face wall record identification 2 (it is 0010 that it, which is converted to tetrad),
Third face wall record identification 4 (it is 0100 that it, which is converted to tetrad), (it is converted to four to fourth face wall record identification 8
1000) binary number is.If encountering the vertex of two face walls boundary, the mark that can record two adjacent surfaces wall is being converted to two
Progress or operation after system number, and using operation result as identification information.Such as：First face wall and the second face wall are in common edge
On vertex be recorded as 0001 and 0010 or operation result 0011, i.e., identification information be 3.
In addition, when rendering each 3D models, processing is hidden if necessary to carry out part (position) to specific 3D models, then
The identification information of part (position) model can be notified to GPU.It specifically, can (variable be used for by uniform variables
Communication interaction between CPU and GPU holds each vertex at each vertex of each 3D models of GPU batch processings and pixel
Vertex Shader code of row executes a Pixel Shader code to each pixel, and the value of the variable is kept not
Become) by operating in the 3D rendering engine code on CPU, pass to the Vertex Shader program codes executed on GPU.
Vertex Shader programs will be recorded in vertex color, tangential data and illumination when handling each vertex of the 3D models
The identification information of part (position) model of one of figure mapping coordinates extracts.This process is a decoded in fact
Journey calculates an integer value from the floating point values of color value, tangent line value or mapping coordinates.It is getting belonging to this vertex
After the identification information of part (position) model, compared with the identification information by uniform variable transferrings.If passed through
The identification information of uniform variable transferrings determines that multiple vertex are specific to part (position) mould corresponding to identification information of transmission
Type, that is, the two is respectively converted into binary number and the result of execution or operation is 0, then needs to be hidden this vertex.
Such as：Identification information by uniform variable transferrings is 4, and expression needs to be hidden processing to third face wall.And it is current
The identification information on vertex is also precisely 4, and the operation result obtained after the two progress or operation is 0, then illustrates that the vertex is exclusive
In third face wall, need to be hidden the vertex., whereas if the two is respectively converted into binary number and execution or operation
Result be 0, then be not necessarily to this vertex is hidden.Such as：Identification information by uniform variable transferrings is 4,
Expression needs to be hidden processing to third face wall.And the identification information of current vertex is 6, is obtained after the two progress or operation
Operation result be not 0, then illustrate that the vertex is not specific to third face wall, but shared by two adjacent surfaces wall, be then not necessarily to pair
This vertex is hidden.
In another alternative embodiment, during carrying out threedimensional model making, if some vertex is multiple localized modes
Type is public, then replicates the public vertex of respective numbers, and records different identification informations, to correspond to the multiple part
Model.If for example, a vertex is that two partial models are public, portion is replicated, two vertex correspond respectively to two parts
Model；If a vertex is that three partial models are public, two parts are replicated, three vertex correspond respectively to three partial models.
In this way in render process, the identification information of the partial model and partial model to be concealed corresponding to current vertex need to be only judged
It is whether identical, as identical, it is hidden, it is normal if different to render, without considering whether as public vertex.
According to a wherein embodiment of the invention, the embodiment of the local processing method of another threedimensional model is additionally provided,
Fig. 2 be according to the flow chart of the local processing method of another threedimensional model of a wherein embodiment of the invention, as shown in Fig. 2,
This method comprises the following steps：
Step S22 parses first identifier letter from the attribute information on each vertex for the threedimensional model for waiting for collision detection
Breath, wherein first identifier information is used to carry out multiple offices that whole piecemeal is handled in the threedimensional model for treating collision detection
The partial model that each vertex is belonged to is identified in portion's model；
Step S24, according to the second identifier information for the partial model for waiting for crash handling and the first identifier on each vertex
Information determines multiple vertex corresponding with the partial model of crash handling is waited for；
Step S26 enables the collision Attribute tuning on multiple vertex corresponding with the partial model of crash handling is waited for non-
State.
Through the above steps, it may be used and parse first identifier letter from the attribute information on each vertex of threedimensional model
Breath, the first identifier information are used in carrying out threedimensional model multiple partial models that whole piecemeal is handled identify each
The mode for the partial model that vertex is belonged to, according to the second identifier information for the partial model for waiting for crash handling and each vertex

To non-enabled state, (i.e. crash handling makes partial model corresponding to it not to the collision Attribute tuning on the corresponding multiple vertex of type
Collision detection is participated in again), can not only a 3D model be subjected to global failure processing to reach, additionally it is possible to realize one
A 3D models carry out the purpose of part (i.e. privileged site) crash handling, to realize enhance in game engine threedimensional model and
The dismounting flexibility of its bounding box promotes the technique effect of game experiencing, and then solves the three-dimensional provided in the relevant technologies
Graphics engine is difficult to realize the technical issues of carrying out hiding part or crash handling to the three-dimensional static model generated offline.
Above-mentioned attribute information can include but is not limited at least one of：Vertex color (color), tangential data
(tangent) in, illumination pattern mapping coordinates.Fine arts personnel can be by above-mentioned first identifier during making 3D models offline
Information is recorded in attribute information.
Optionally, in step S24, according to the second identifier information for the partial model for waiting for crash handling and each vertex
Can also include step performed below before first identifier information determines multiple vertex corresponding with the partial model of crash handling is waited for
Suddenly：
Step S23 chooses from the threedimensional model for wait for collision detection and waits in response to the touch control operation that user interface receives
The partial model of crash handling.
Collision body needs to depend on specific 3D models, is that 3D models indicate shape in physical world or simplifying for physical engine
Formula.Such as：The collision body of one personage's 3D model can be a capsule body 3D model, and the collision body of an automobile 3D model can
To be a cuboid box 3D model.The purpose for creating collision body is：Improve operational efficiency and calculating speed.Certainly,
3D models itself can be set to collision body for the calculating of physical engine.
Assuming that game player manipulation game role under scene of game using particular tool (such as：Hammer) tap house
A wherein face wall (being equivalent to the above-mentioned touch control operation received in response to user interface), then for this static state three of house
For dimension module, this face wall be the house whole threedimensional model in wait for the partial model of crash handling, including it is special
Processing should be disabled by belonging to vertex.In addition, the bounding box in the house participates in collision detection due to needing, and due to that above-mentioned face wall
It is got through, the bounding box department pattern opposite with this face wall no longer needs to participate in collision detection, therefore, this department pattern institute
Including the collision attribute on exclusive vertex should be subjected to crash handling.
Optionally, in step s 24, according to the second identifier information for the partial model for waiting for crash handling and each vertex
First identifier information determine that corresponding with the partial model of crash handling is waited for multiple vertex may include step performed below：
The first identifier information on each vertex is compared with second identifier information by step S241 respectively, is obtained exclusive
In the vertex for the partial model for waiting for crash handling；
Step S242 will be specific to the localized mode for waiting for that the vertex of the partial model of crash handling is determined as and waits for crash handling
The corresponding multiple vertex of type.
For collision body, above-mentioned similar determination method can also be used.Because of the collision body of a 3D model,
In fact and a 3D grid.Only in general collision body be 3D models reduced form, vertex quantity will be less than
The 3D models depended on.It therefore, equally can be by the code identification information of the part (position) belonging to each vertex on collision body
To the vertex attribute information (such as：Vertex color, tangential data, illumination pattern mapping coordinates etc.) in.Then, collision inspection is being carried out
When survey process, according to the identification information of part (position) model for waiting for collision detection, it can so that being specific to this waits for collision detection
Part (position) model whole vertex collision attribute failure.In other words, when carrying out the ray detection of collision body, ignore
Collide the vertex of attribute failure and its triangle of composition.Processing in view of collision body is completed in computer system, with 3D models
Processing compare, the former can be completed by executing the program code write on CPU, and the latter need CPU and GPU it
Between communicated, that is, need CPU program codes to cooperate to complete with GPU program code.Accordingly, with respect to the office of collision body
Portion hides processing, and the part compared to render process hides processing, and operating process is simpler, treatment effeciency higher.
