An operation action that does not require emphasis for simplicity is defined as a non-emphasized component. When modeling non-key components, animation, such as auxiliary rod telescopic animation on the foot limiter, is directly produced in modeling software.

firstly, placing all armrests on a bulkhead of a spacecraft in modeling software, and building corresponding virtual bodies, wherein each virtual body is named according to the number and specification of the armrest, and all the virtual bodies are intensively mounted on a WT_Handlebox reference model on the origin of a coordinate system of a spacecraft body. When the model is exported, the WT_Handlebox and all virtual bodies are integrally exported; the models of the three armrests are respectively modeled according to the length and respectively exported, and the body coordinate system of the armrests is arranged on the armrests mounting surface.
Secondly, loading a WT_Handlebox reference model and a handrail model in a UE4 program blueprint, and placing the WT_Handlebox on the origin of the body coordinate system of the spacecraft in the program. A blueprint can be created in advance, and handrail models of corresponding size types are respectively mounted according to the skeleton names converted by the virtual bodies on the wt_handlebox model. And checking the assembled state of the model, wherein the same armrest uses the same armrest model file, and the actually imported armrest model files only have 3 files of large, medium and small types, so that the number of the models needing to be imported into the UE4 is reduced.

When the program is started, the automatic assembly loading of all armrest models is carried out by reading the attribute of the json file.
The method has three advantages, namely, when the appearance size of the spacecraft changes, only the position of the concentrated node WT_Handlebox in the program is required to be moved integrally, the relative position between handrails does not change, the situation that each handrail needs to be changed before is solved, and the working efficiency is improved; 2. if the position and the posture of the single armrest are changed, the skeleton slot of the single armrest can be modified, so that the problem that the single armrest cannot be modified due to integral introduction is avoided; 3. when the armrest model is replaced, only the corresponding single armrest model file which is originally imported is needed to be replaced, and the position, the assembly relation and the like of the model are not needed to be reset. The method is suitable for the situation that the same appearance model is numerous, such as an engine model of a spacecraft, an outside handrail, an outside antenna and the like.

and controlling information transmission and information analysis of the model based on the model control command.
Specifically, for the display of the cabin outlet process, the quick movement and the posture change of the model are controlled, and besides the model creation rule, a series of general visual control commands are designed according to the embodiment of the invention, and the information transmission and the information analysis of the model are realized by setting the model control commands and controlling the model based on the model control commands. Specifically, the model control command includes a model position movement, a model mounting relationship switching, a model display hiding control, a model animation control, a astronaut posture adjustment, etc., which can be specifically shown in table 1, specifically, the actual situation is taken as a reference, and the method is not limited to the list in table 1.
TABLE 1 model control commands
The optimization method of the astronaut cabin-leaving operation model provided by the embodiment of the invention is preferable, and the method further comprises the following steps:
setting a highlight display parameter, wherein the highlight display parameter at least comprises one of the following: basic texture, basic color, highlight color, timer, and flicker speed;
generating a highlight flickering control command based on the highlight display parameter;
and controlling the highlight display of any part in the model through the highlight flickering control command.
In a specific embodiment, in three-dimensional visualization, in order to predict an upcoming action, a component to be operated, or highlight a certain component in advance, it is necessary to highlight the action and the spacecraft component, so that the model has a visual effect of being bright in front of the eyes and focusing attention, that is, highlight display is performed. The traditional method is to create materials for each model, set self-luminescence, and each model needs to be set independently and is loaded statically, so that the requirement of changing materials in real time is not met. For the out-of-cabin projects with a large number of models and frequent demand change, the high-gloss color and flicker frequency are adjusted in real time, so that the consumed workload is large, and the working quality is seriously influenced.
In order to improve the working efficiency and quickly meet the display requirement, the embodiment of the invention controls the highlight display of any part in the model by setting the highlight display parameter and generating the highlight flicker control command based on the highlight display parameter. Specifically, the method is realized by using a UE4 blueprint interface based on a visual script node, and the process is as follows:
(1) Preparation of high-gloss material
First, highlight display parameters are set, wherein the highlight display parameters comprise: basic texture, basic color and highlighting color, timer and blinking speed.
Secondly, the basic color and the highlight color are subjected to condition control by a mixing function. When the highlight parameter is set to 0, the model material is mainly based on the basic material and is expressed as a default attribute; when the highlight parameter is set to be more than 0, the highlight intensity of the model material output according to the set parameter is different, and a proper value can be adjusted according to the requirement. Thereby achieving the function of mutually switching the highlight material and the basic material. Meanwhile, in order to realize the dynamic flicker function, the display device also comprises a timer and a flicker speed, and is adjusted according to the setting of the highlight display parameters. The variable nodes to be regulated are all open as parameter nodes, so that the highlight display parameters can be directly transmitted to any model material for use.
Finally, after the material example is manufactured, a new material is copied and added to the model part, the model material slot is named, and the control of the model highlight flicker is controlled by the name. And opening the model materials, selecting the manufactured highlight materials from the parent options, and modifying the basic material texture of each part according to the appearance difference of each model part.
(2) Acquisition of dynamic Material
In the three-dimensional visualization program, in order to dynamically change the material of the cabin-out model in real time and realize the effect of highlighting the component, the parameter change is required to be dynamically carried out on the material of the component model, and when the model is required to be highlighted and flash-displayed, a console is required to send a highlighting and flashing control command to the three-dimensional software. After the three-dimensional software receives an instruction for changing the model, the name of the part model is obtained, and the index ID of the model material is found through the model name, so that the material used by the model is obtained. A dynamic acquisition material information function getdynamicartial is written. The function holds all data for the material by index ID and is stored in the newly created array of createddynamicartial function. In order to reduce the resource utilization rate, the parameters of the model material are stored in the dynamic acquisition storage array after the same model material command is received once, and dynamic acquisition is not needed when the parameters of the model material are changed later.
(3) Control of dynamic materials
With the model control command, a highlight flash control command needs to be sent each time the model needs to be highlighted. The command is defined as the CommonHighlight command, generated by the highlighting parameters. The command line includes: spacecraft name, model part name, material name, highlighting, flashing speed, highlighting color (RGB), etc., for example CommonHighLight, HXC, TX, m_tx,5.0,0.8,1.0,1.0,1.0, represent turning the antenna model part m_tx material on the core cabin white, highlighting intensity 5, flashing frequency 0.8 seconds once. The CommonHighLight command sends the model part name to the dynamic acquisition texture function GetDynamicommateval, which extracts the acquired model part texture parameters and sends the extracted model part texture parameters to the SetScalarParameterValue function and the SetVectoParameterValue function. The SetScalarParameterValue function is to modify the parameters of the values of the float types on the material; the SetVectorParameterValue function functions to modify parameters in the texture that are related to color (RGB). The embodiment of the invention dynamically controls the highlight brightness, the flicker speed and the highlight color. Meanwhile, in order to avoid data congestion, sequence allocation setting is carried out, and after a highlight flickering control command is received, the parameters are changed according to the sequence.
The optimization method of the astronaut cabin-leaving operation model provided by the embodiment of the invention is preferable, and the method further comprises the following steps:
generating a script control command; the script control command control is used for controlling astronauts and cabin-outlet components;
and storing the script control command in the configuration file.
Specifically, in order to edit the cabin-outlet flow rapidly, intuitively and in real time, the embodiment of the invention carries out script design and application through the script editing unit to generate script control commands, thereby realizing the functions of controlling the display, movement, rotation, mounting, cabin-outlet visual angle and the like of astronauts and cabin-outlet components in real time.
Script functional area design description:
1) Script list display box: for selecting scripts to be applied
2) Script list toolbar: scripts for adding delete and rename lists
3) Script content display box: displaying specific items in a script
4) Script playing toolbar: control of play script
5) Script command toolbar: for controlling insertion, deletion, up-and-down movement and saving of "commands
6) Command type selection field: for selecting the type of command to be inserted
7) Command edit bar: for editing specific command details
And manufacturing all operations in the cabin outlet process into independent script control commands according to cabin outlet requirements, and storing the script control commands in the configuration file. Therefore, script control commands can be automatically or manually sent through time sequence according to the cabin outlet flow to control the cabin outlet components and the model state, and the requirements of cabin outlet tasks are met. The content of the specific script control command comprises the following categories:
