In the embodiment, in order to enable a user to quickly find out a corresponding part module, the characteristics of office chair composition are combined, and the established office chair product part model library is subjected to modular classification. The office chair is divided into a backrest module, a seat board module, an armrest module, a support module and other modules, and finally the construction of the virtual part library is completed.
As shown in fig. 2, the backrest module includes a backrest model library and a corresponding attribute model library; the seat board module comprises a seat board model library and an attribute model library corresponding to the seat board model library; the armrest module comprises an armrest model library and a corresponding attribute model library; the support module comprises a chassis model library, a gas rod model library, a chair foot model library and a corresponding attribute model library; other modules include a headrest model library, a top waist model library, and the like, and their corresponding attribute model libraries.
In the human-computer interaction module 13, virtual parts in the model library are controlled and selected through VR hardware equipment, and the selected virtual parts are assembled, so that personalized customization of the office chair is completed.
When a software environment is constructed and a virtual part model library is obtained, human-computer interaction is further established
The method specifically comprises the following steps:
the establishing module is used for establishing a virtual scene;
in this embodiment, a scene between 4m × 6m virtual sample plates is established, which mainly includes an illumination lamp, a window, a door, a wallpaper sticker, a floor sticker, furniture, and the like. The position of the sun is consistent with the real world, and the light and shadow effect of all objects in the virtual scene is determined by the position of the sun and the intensity of the light of the sun.
The control module is used for controlling and selecting each part module in the virtual part model library through the control handle;
when the user wears the helmet and enters virtual reality, the display screen in the helmet is rendered in real time at a refresh rate of 90 Hz. And 4.5m by 5.5m of mesh virtual safety walls are established in the scene to remind and protect the safety of operators. The two control handles are displayed in a virtual scene in real world with an absolute position relative to the person. And the left control handle and the right control handle are distinguished by rays with different colors, wherein red is the left control handle, and blue is the right control handle. The starting point of the ray is the symmetrical center of the control handle, and the direction is the longitudinal symmetrical line of the control handle. The keys in the left control handle comprise 1, 2, 3, 4, 5 and 6, and the keys 1, 2, 3 and 4 are used for adjusting the spatial position of an operator in a scene; the key 5 is used for calling out/canceling a menu of the office chair virtual part model library; the key 6 is used to select/disengage the part module and its property menu. Specifically, the operator moves forward by long pressing the key 1; the operator moves to the right by long pressing the key 2; the operator moves backwards by long pressing the key 3; by long pressing the key 4, the operator moves to the left. And (3) pressing the key 5 for a short time to call out a menu of the office chair virtual part model library, wherein the position of the menu is the intersection point of the ray and the ground in the virtual scene and is vertical to the ground, and the key 5 is pressed for a short time again to disappear.
The menu of the virtual part model library comprises a forward button, a backward button, a backrest module, a seat board module, an armrest module, a support module and other modules, wherein each module comprises a model library and an attribute model library thereof. And the motor forward button returns to the upper menu, and the backward button is clicked to return to the lower menu. When the ray of the left control handle is intersected with a certain module area, the key 6 is pressed for a short time, a certain module is selected to enter an attribute model library menu, one part, such as an armrest, is selected, the key 6 is pressed for a long time, the part is dragged out of the menu to enter a virtual scene, the spatial position of the left control handle and the selected part is unchanged, and the part can be rotated back and forth, left and right. The key 6 is released, and the part is disengaged from the control.
The cases of the right control handle comprise 1 ', 2', 3 ', 4', 5 ', 6'. The method specifically comprises the following steps: the attribute menu of the part is called out by pressing the key 1 'for a short time, the attribute menu comprises basic three-dimensional size, material, weight and price, and the attribute menu disappears by pressing the key 1' for a short time again. A short press of key 5' returns the operator to the initial position set with the virtual scene. The function of the key 6' is the same as the function of the left control handle key 6. The keys 2 ', 3 ', 4 ' are not provided with a function.
And the assembling module is used for assembling the selected part module through the control handle to obtain a virtual office chair model.
During assembly, the two control handles respectively control the two parts, when the distance between the central points of the contact surfaces of the two matched parts is less than 5cm, and the included angle of the normal vectors of the contact surfaces is less than 5 degrees, after an operator loosens the keys 6 and 6 ', the two parts become a parent-child relationship, the assembly is completed, the green highlight display of the matching surfaces is realized, the original color is recovered after 2 seconds, the matched objects can move simultaneously by long pressing the keys 6 or 6 ', and the keys 6 and 6 ' are simultaneously pressed for long time to operate different parts, so that the parent-child relationship is removed.
In order to avoid the influence of the assembly error accumulation of parts on the subsequent assembly and the final assembly completion state, a set of flow algorithm for matching and correcting is designed. Specifically, one part is rotated to enable the axis of the part to be parallel to the axis of the other part, then the axis of the part is moved to be circumferentially overlapped with the other part, then the part is moved to be attached to a contact surface of the part to be assembled, the whole color of the last two matched parts is changed and is displayed in a green highlight mode, and the original color is recovered after 2 seconds. If the relative position of the successfully assembled parts changes, there are two situations, as shown in FIG. 3: (1) and (3) whether the changed center distance and the changed normal angle are both smaller than or equal to a threshold value (such as 5), if so, the part is still in an assembly state, and the color of the part is not changed. (2) And (3) judging whether the changed center distance or normal vector angle is larger than a threshold value (such as 5), if so, determining that the part is out of the assembly state, releasing the parent-child relationship, highlighting the green color of the part, and recovering the original color after 2 seconds.
