101, it is set to the change point of interface cartoon close node, configures starting point, terminal and the curvature of closing node.
Being set to the change point of interface cartoon close node, have multiple change point, then arrange multiple passes node in interface cartoon, corresponding one of each change point closes node, like this other non-changing point, then without the need to analog track and then saving resource.
Closing Node configuration starting point, terminal and curvature for each, each closes the parameter of node is different, therefore can show 3-D effect on the basis of two-dimension layer.
102, each 3 D motion trace closing node is set up by the starting point of pass node, terminal and curvature according to physical principle.
Closing node is the key point showing 3-D effect on the basis of two-dimension layer, the 3 D motion trace closing node must meet physical principle, therefore can set up each 3 D motion trace closing node by the starting point of pass node, terminal and curvature according to physical principle.
Curvature configures in a step 101, in order to can true representation close node motion track can also adjust curvature according to physical principle, and then set up each close node 3 D motion trace.
Consider the situation that there is multiple passes node, it is possible to calculate the parameter that influences each other closed between node according to physical principle, then according to the parameters revision curvature that influences each other, then set up each 3 D motion trace closing node. For closing node for one, the mean value of the parameter that influences each other and the product of curvature equal to revise curvature.
103, each 3 D motion trace closing node when interface cartoon image moves is preserved.
Preserve each 3 D motion trace closing node when interface cartoon image moves, delete when interface cartoon image moves except each motion track closing node. Resource and storage space can be saved like this.

Drop the water surface for water droplet. Water droplet drops from top to down, has the process that one section of water droplet picture moves down, water droplet distortion time downward, and water droplet encounters the water surface and the moment of water droplet distortion.
Step one: by circle globule picture according to being divided into 4 passes node (node1, node2, node3, node4) up and down.
Configuring 4 virtual three-dimensional point Z axle positions closing node is [pos1 (x1, y1, z1), pos2 (x2, y2, z2), pos3 (x3, y3, z3), pos4 (x4, y4, z4)], the fixing curvature in the distance center of circle is (curve1, curve2, curve3, curve4), and aiming spot is (dest1, dest2, dest3, dest4).
Step 2: calculate the data acquisition that the set time puts water surface process according to gravity formula and fixing flexometer.
Map1 ((t1, (x11, y11, z11), (t2, (x12, y12, z12) ... (tn, (x1N, y1N, z1)), n) wherein (tn, (x1N, y1N, z1N)) i.e. dest1;
Map2 ((t1, (x21, y21, z21), (t2, (x22, y22, z22) .. (tn, (x2N, y2N, z2)), n) wherein (tn, (x2N, y2N, z2N)) i.e. dest2;

Step 3: 4 close node integrally, restrict mutually, it is possible to use mechanics formula or additive method calculate 4 and close the parameter that influences each other between node.
Utilizing the parameters revision that influences each other to close the curvature of node, such track more meets the two-dimentional oriented manifold compacted. Such as time point t1, the radian that affects of pos2 is arc1 by pos1, the radian that affects of pos2 is arc2 by pos3, the radian that affects of pos2 is arc3 by pos4, the curvature of the pos2 of setting is curve1, can simply calculate and now revise curvature is curve1* (arc1+arc2+arc3)/3, by curvature now, it is possible to calculate pos2 position at that time. The change of curvature, it is possible to realize the effect of distortion.
Step 4: preserve each 3 D motion trace closing node when interface cartoon image moves.
The above, be only the better embodiment of the present invention, be not intended to limit protection scope of the present invention. Within the spirit and principles in the present invention all, any amendment of doing, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
