As shown in fig. 1, the present embodiment discloses a method for implementing a three-dimensional current light effect, the principle of the method is to slice a current stereo model overlaid on an entity model based on a simple slicing program to obtain a current light flowing effect, and the method has the advantages of simple operation, few steps, high accuracy and easy understanding. The basic idea and the operation steps of the implementation method are as follows:
step S1: manufacturing a wire solid model by using three-dimensional drawing software;
step S2: setting the material of the wire solid model;
step S3: copying the electric wire solid model in situ as a current solid model, so that the current solid model completely covers the electric wire solid model;
step S4: setting the material of the current three-dimensional model;
step S5: and adding a slicing program for the current stereo model, and setting slicing animation to enable the current stereo model to generate an effect of flowing along the electric wire solid model, so as to simulate a three-dimensional current light effect.
In practical applications, one or more analog streamers can be produced as required, and the following description will be given in detail by taking the multiple analog streamers as an example:
step S1: firstly, 3DSMAX drawing software (or other three-dimensional drawing software) is used for manufacturing a wire solid model, then a plurality of wire solid models are copied, and parameters such as the curvature, the position and the like of each wire solid model are changed, so that the plurality of wire solid models are randomly distributed.
Step S2: in the present embodiment, the material of the wire dummies is set to be plastic, the surface of the plastic has reflective details, and different colors are set for the plurality of wire dummies (as shown in fig. 2).
Step S3: the plurality of wire dummies that have been constructed in the copy-and-paste step S2 are used as the current solid model. Because the current three-dimensional model is obtained by directly copying and pasting the electric wire solid model in situ, the current three-dimensional model is covered on the electric wire solid model, and the finally simulated current light can be ensured to completely cover the electric wire solid model.
Step S4: firstly, one of the current three-dimensional models is selected, the material of the current three-dimensional model is changed into the light material (namely, the luminous material), the characteristic of the material is that the current three-dimensional model can be used as an illuminator to generate the luminous effect, then the color of the luminous material is changed, and finally, the material of other current three-dimensional models is changed into the light material by adopting the same method, and the color is set.
Step S5: in this embodiment, the specific operation process of step S5 includes:
step S51: adding a slicing program to one current stereo model;
step S52: and moving the cross-section tool of the slicing program to the starting end of the electric wire solid model covered by the current solid model, and moving the cross-section tool to the tail end of the electric wire solid model under the motion key frame recording state, so that the current solid model generates an effect of flowing along the electric wire solid model, and a three-dimensional current light effect is simulated. Since the physical form of the wire phantom is curved, the orientation data of the cross-section tool is changed while the cross-section tool is moved to be substantially perpendicular to the wire phantom.
Step S53: and repeating the steps S51 and S52 to complete the slice animation setting of other current stereo models and the simulation of the three-dimensional current light effect (shown in FIG. 3).
Since there is a gap after the cross section of the wire physical model is cut by the slicing program, in order to fill up the gap, in this embodiment, the method for implementing the three-dimensional galvano-optical effect further includes step S6:
and adding a hole filling program for the wire solid model, so that the notch of the cut of the wire solid model is filled by the slicing program.
In conclusion, compared with the prior art, the method provided by the invention is simple to operate, has few steps, is high in accuracy and is easy to understand. The technical problems of complex steps, low operation speed, low accuracy and poor effect of the existing processing method are well solved.
It should be noted that this embodiment is only an example of the method of the present invention, and besides the wire dummies in the above embodiments, the dummies and the solid models in the present invention may have various shapes, such as square, cylinder, strip-shaped surface, strip-shaped irregular shapes, and the like. The streamer effect is based on the current flowing treatment of the original entity model, the accuracy of the original entity model is guaranteed, the streamer effect can be applied to various light flowing effects, and the streamer effect is not limited to current light of wires and also comprises energy infusion and transmission commonly seen in movie and television screenplay, data transmission in a circuit and the like. Modifications and variations will occur to those skilled in the art in light of the foregoing description, and it is intended to cover all such modifications and variations as fall within the true spirit and scope of the invention as defined by the appended claims.
