In order to make the above and other objects, features and advantages of the present invention more comprehensible, preferred embodiments of the present invention will be described in detail below together with the accompanying drawings.

A preferred embodiment of the computer three-dimensional object model operating method of the present invention comprises the following steps:

Please refer to FIG. 3 and FIG. 4 , a generating step S1 uses a 3D design software to simulate and construct at least one cabinet object 1 from several sub-objects 2 . In this embodiment, the three-dimensional design software can be an interior design software, and simulate several sub-objects 2 that constitute the cabinet object 1, which can include a top board 2a, a bottom board 2b, a back board 2c, two side boards 2d, At least one door panel 2e and at least one inner sub-component 2f. Wherein, the inner sub-part 2f is located inside the cabinet object 1, and the type of the inner sub-part 2f can be a partition or a drawer (such as a pull basket, an inner drawer or a tie drawer), etc., which is not limited by the present invention. Specifically, the top board 2a, the bottom board 2b, the back board 2c and the two side boards 2d can even be matched together with the at least one door board 2e to form an accommodating space S around together, and the accommodating space S can The at least one inner part 2f is provided.

Please refer to FIG. 3 and FIG. 5 , a cabinet object editing step S2 , the cabinet object 1 has a touch range 11 , and the touch range 11 of the cabinet object 1 can be all areas within the border of the cabinet object 1 . The cabinet object 1 has a selected state, and when the cabinet object 1 is not in the selected state, it cannot be edited by the 3D design software. When the three-dimensional design software edits the cabinet object 1, it simulates that several sub-objects 2 constituting the cabinet object 1 will be scaled or displaced synchronously; that is, the top plate 2a, the bottom plate 2b, the back plate 2c, and the two side plates 2d , the at least one door panel 2e and the at least one inner component 2f will be scaled or displaced synchronously.

In addition, there is a selection mark 12 within the touch range 11 of the cabinet object 1 , and the selection mark 12 is used to generate a first instruction by clicking on an operation pointer P, which can be, for example, a mouse cursor. The 3D design software sets the state attribute of the cabinet object 1 to the selected state only when receiving the first instruction. In other words, even if the operation indicator P is within the touch range 11 of the cabinet object 1 , directly clicking on the cabinet object 1 cannot change the status attribute of the cabinet object 1 into the selected state. In addition, the uppermost layer of the visual display of the cabinet object 1 (interpreted according to the concept of "layer", rather than the top of the cabinet object 1) is to simulate one of the sub-objects 2 that constitute the cabinet object 1, and the selection mark 12 is located at The upper layer of the visual display of the child object 2 prevents the selection mark 12 from being hidden by the child object 2 and cannot be clicked by the operation pointer P. Preferably, when the operation indicator P touches the touch range 11 of the cabinet object 1, the three-dimensional design software sets the selection mark 12 to display; the operation indicator P moves to the touch range 11 of the cabinet object 1 Otherwise, the 3D design software sets the selection mark 12 as hidden.

Please refer to FIG. 5, when the operation indicator P moves within the touch range 11 of the cabinet object 1, the three-dimensional design software can frame the front boundary of the cabinet object 1 by a frame line 13; that is, the The frame line 13 is to frame a two-dimensional plane, rather than a three-dimensional space range. For example, when the cabinet object 1 is presented in the three-dimensional viewing angle shown in FIG. The boundary formed by the bottom plate 2b and the two side plates 2d (that is, framed along the front boundary of the cabinet object 1); however, even if the cabinet object 1 is presented in other three-dimensional perspectives, its back, left or right sides are visually When the uppermost layer is displayed, the frame line 13 will still be framed along the front boundary of the cabinet object 1, but will not be framed at the boundary of the back panel 2c or the side panel 2d.

Please refer to Figure 6, when the cabinet object 1 is in the selected state, the 3D design software can frame the front boundary of the cabinet object 1 by another frame line 14, so that the user can know the position of the cabinet object 1 The state property has changed to the selected state. Similar to the above, no matter the cabinet object 1 is presented in any three-dimensional viewing angle, the frame line 14 will be framed along the front boundary of the cabinet object 1 .

Please refer to Figures 5 and 6, for easy identification, the above-mentioned two frame lines 13 and 14 can be presented in different colors, line types or thicknesses; for example but not limited, the frame line 13 is used to represent the operation index P moves into the touch range 11 of the cabinet object 1, and the color of the frame line 13 can be yellow (or a little chain line); the frame line 14 is used to indicate that the cabinet object 1 is in the selected state, And the color of the frame line 14 can be red (or two-dot chain line). It is worth mentioning that, in order to prevent the display of the two frame lines 13 and 14 from interfering with each other, when the display conditions of both are satisfied at the same time, the 3D design software will preferentially display the frame line 14; that is, the cabinet object 1 is in the In the selected state, and the operation indicator P is within the touch range 11 of the cabinet object 1, the 3D design software only selects the cabinet with the frame line 14 indicating that the cabinet object 1 is in the selected state. The front boundary of object 1.

Also, when the several sub-objects 2 that constitute the cabinet object 1 include at least one door panel 2e, click the selection mark 12 on the operation indicator P to generate a first instruction, so that the status attribute of the cabinet object 1 becomes the selected While in the middle state, the 3D design software can set the appearance attribute of the at least one door panel 2e as a first option after receiving the first instruction, and the first option can be, for example, transparent to make the cabinet object 1 The inner sub-component 2f can be seen without being obscured by the door panel 2e (as shown in Fig. 6). In addition, when the state attribute of the cabinet object 1 is the selected state, the selection mark 12 can be clicked again through the operation indicator P to cancel the selected state of the cabinet object 1, or the selected state of the cabinet object 1 can be canceled through the operation The pointer P clicks anywhere outside the touch range 11 of the cabinet object 1 to cancel the selected state of the cabinet object 1 .

Please refer to Figures 3, 7, and 8, the computer 3D object model operating method of this embodiment may also have a sub-object editing step S3. Simulate that several sub-objects 2 constituting the cabinet object 1 each have a touch range 21 and a selected state. Similar to the above, when the operation indicator P moves within the touch range 21 of any sub-object 2, the The 3D design software can frame the front boundary of the sub-object 2 by a frame line 22 (as shown in FIG. 7 ). When the sub-object 2 is in the selected state, the 3D design software can frame the front boundary of the sub-object 2 by another frame line 23 (as shown in FIG. 8 ). For ease of identification, the above-mentioned two frame lines 22, 23 can be presented in different colors, line types or thicknesses; This is the limit. When the sub-object 2 is in the selected state, and the operation indicator P is within the touch range 21 of the sub-object 2, the 3D design software only uses the frame line to indicate that the sub-object 2 is in the selected state 23. Frame the front boundary of the sub-object 2. In addition, when the state attribute of the cabinet object 1 is the selected state (as shown in Figure 6), even if the operation indicator P moves within the touch range 21 of the child object 2, it still cannot display the touch The frame line 22 of the child object 2.

Please refer to Figures 9 to 11, and continue to take another type of cabinet object 1 as an example for illustration, in order to avoid this case being limited to the type of cabinet object 1 shown in Figures 4 to 8, and this case is different All the operation and control principles are exactly the same among the external cabinet objects 1, so the above-mentioned operation and control principles can be generally applied to the cabinet objects 1 of the type shown in Figures 9-11, and the following operation and control principles It can also be commonly used in the cabinet object 1 of the type shown in Figs. 4-8.

Please refer to Figure 9, when the operation indicator P is within the touch range 11 of the cabinet object 1 and within the touch range 21 of one of the sub-objects 2 at the same time, the 3D design software system can be as shown in Figure 10 , using different colors, line types or thicknesses to present the frame line 13 of the cabinet object 1 and the frame line 22 of the sub-item 2 . For example, when the operation indicator P is within the touch range of the cabinet object 1 and a door panel 2e (or an inner sub-component 2f) at the same time, the three-dimensional design software system can make the frame line 13 of the cabinet object 1 yellow (or a little chain line), and make the frame line 22 of the door panel 2e (or the inner sub-component 2f) green (or dotted line); Displayed first.

Please refer to Figures 3, 9, and 11, the computer 3D object model operating method of this embodiment may also have a door panel state switching step S4. The appearance attribute of the door panel 2e has a second option and a third option in addition, the second option can be closed/displayed (state shown in Figure 9), and the third option can be opened/hidden (as shown in Figure 11 state shown in the figure). When the appearance attribute of the door panel 2e is the second option, the operation indicator P will not be able to touch the touch range 21 of the inner sub-component 2f shaded by the door panel 2e; when the appearance attribute of the door panel 2e is the third option , the operation indicator P will be able to touch the touch range 21 of the inner sub-component 2f.

Wherein, for the appearance attribute of the door panel 2e, a second instruction can be generated through a click action of an input device, and the 3D design software can assign the appearance attribute of the door panel 2e to the second instruction when receiving the second instruction. Switch between the two options and the three options. That is, when the 3D design software receives the second instruction, and the appearance attribute of the door panel 2e is the second option, the 3D design software switches the appearance attribute of the door panel 2e to the third option, so that the interior At least a part of the component 2f is not covered by the door panel 2e (as shown in FIG. 11 ), and the operation indicator P can touch the touch range 21 of the inner sub-component 2f. On the other hand, when the 3D design software receives the second instruction again, it can switch the appearance attribute of the door panel 2e back to the second option, so that the door panel 2e can cover the inner part 2f again (as shown in Fig. 9 shown).

Specifically, as shown in Figure 9, when the appearance attribute of the door panel 2e is closed, the touch range 21 of the door panel 2e can be a closed touch range 21a; as shown in Figure 11, the appearance of the door panel 2e When the attribute is open, the touch range 21 of the door panel 2e may be an open touch range 21b. Accordingly, when the appearance attribute of the door panel 2e is closed, the touch range 21 of the inner sub-component 2f covered by the door panel 2e will be located between the closed touch range 21a of the door panel 2e and the touch range 11 of the cabinet object 1 The lower layer, and the operation indicator P cannot touch the touch range 21 of the inner sub-component 2f. The appearance attribute of the door panel 2e is that when the door panel 2e is opened, at least a part of the inner sub-component 2f will not be covered by the door panel 2e, so that the inner sub-component 2f has at least a partial touch range 21 that does not touch the opening of the door panel 2e. The areas 21b overlap, and the operation pointer P can touch the touch area 21 of the inner sub-item 2f, and then click the inner sub-item 2f, so that the inner sub-item 2f becomes selected for editing.
