To make the objects, technical solutions and advantages of the present invention clearer, clear and definite, develop simultaneously embodiment pair referring to the drawings
The present invention is described further.
As shown in Figure 1, the invention discloses a kind of implementation method of simple rule model variation effect, this method is suitable for
Some are simple, more the variation effect of rule/symmetrical model, are particularly suitable for constantly repeating, and with random
Property animation effect, as fluid/water spend splashing effects, flower is burst forth, sapling germinating growth, liquid drop onto ground, sphere
Landing rebound effect etc..Wherein, which specifically comprises the following steps：
Step S1:A three-dimensional model is built, as primary model data；The three-dimensional model needs the difference according to making
Effect determines that such as making spray of water effect needs hollow model, and making sphere pop effect needs solid model etc..
Step S2:By editing the vertex position data of three-dimensional model, the three-dimensional model of a deformation is obtained；The vertex
Refer to the endpoint for forming the line segment of three-dimensional model.
Step S3:By editing the dough sheet data of distorted pattern, the initial volumetric model for having apperance at the beginning of one is obtained；It is described
Dough sheet data, refer to form a plane of three-dimensional model or the data of curved surface.

The physical model that four steps obtain more than can be used for follow-up animation effect and make.
Step S5:Changed using logging program to record the rule of the vertex position of physical model, obtain physical model
Variation effect animation；Described rule change, refers to the three-dimensional mould under the natural law action rule of power (plant growth rules)
The change of shape caused by type.
Further, in order to form a continuous, coherent animation effect, the ornamental value of animation, the realization are improved
Method further includes step S6:The animation that physical model changes is cloned several, and sets the time of occurrence of each clone's animation
It is later than previous animation, so as to form the variation effect constantly repeated.
Further, in order to make physical model change procedure it is more round and smooth, naturally, implementation method described in the present embodiment is also
Including step S7:By round and smooth modification program, change the vertex distributed quantity of physical model, being distributed the grid on vertex becomes round
It is sliding.
Embodiment 1：
Implementation method of the present embodiment based on simple rule model variation effect provided by the present invention, with spray of water
(the art up splashing effects of various liquid are equally applicable) as an example, what the present invention will be described in detail realizes process and specific step
Suddenly：
Step SS1:A three-dimensional model is built, as original model data；As shown in Fig. 2, because spray is in itself
Middle hollow out, to the shape of external diffusion, so the three-dimensional model is preferably arranged to torus by the present embodiment, the torus is same
It is hollow, is more suitable for the basic model of spray making.

Type, by the recording of the metamorphosis to physical model, can obtain true, natural spray of water effect, concrete operations step
It is rapid as follows：
Step SS5:Open record program, and the original state of spray model is recorded, all vertex Dou Hui of spray model
Gather in an a small range, and the position on all vertex is not overlapping, and spray model is in and tightens form.With reference to Fig. 4 to Fig. 7
It is shown, the logging program be used for record spray since produce (start) to disappearance (end) this process metamorphosis, the form
A series of change for shapes that change is mainly served as theme with the time, so as to obtain continuous, coherent animation effect.
Step SS6:The vertex data of spray model is progressively adjusted, makes its gradually stretching, extension, expansion around；This stage is water
The ascent stage that flower is burst forth, opening are gradually magnified, and position gradually rises.
Step SS7:After the vertex position of spray model reaches peak, moved down, produced to four by control vertex
The animation effect of week diffusion；This stage is the decline stage that spray is burst forth, and aperture position is gradually reduced, and finally falls into the water surface.
Further, the preferred solution as the present embodiment, the implementation method further include step SS8:By the animation effect
Several are cloned, the time of occurrence of each animation is later than previous animation, so as to form the variation effect constantly repeated.Two
The repetition of a or multiple sprays, which is produced and disappeared, to be the more dynamic elements of animation effect addition, be conducive to lifting entirety
Animation effect.
Further, the implementation method that the present embodiment is provided further includes step SS9:By round and smooth modification program, change
The vertex distributed quantity of spray model, being distributed the grid on vertex becomes round and smooth.Step SS9 can be arranged on before step SS8
Or afterwards.As shown in Figure 8 and Figure 9, after changing the quantity on vertex and distribution situation by round and smooth program, spray model becomes round
Moisten, have three-dimensional sense, closer to real spray.
Further, vertex movements track of the spray model before the processing of track smoothing procedure is as shown in Figure 10, from
State 1, state 2, state 3 arrive state 4, and the transition of deformation is not smooth, unnatural, lack the sense of reality.Pass through smooth trajectory program
After processing, as shown in figure 11, deformation locus is substantially into parabola, the round and smooth nature of transition.
In conclusion on the basis of the vertex data displacement knead dough sheet data deformation of the invention based on three-dimensional model, pass through
Logging program records this deformation process, and step is simple and convenient to operate, versatility is good, and can be dynamic by cloning
The mode of picture reaches the effect of repetition presentation, is realized close to real variation effect by round and smooth modification program.Solve well
