The invention provides an AR-based chemical substance automatic synthesis method in combination with figures 1-9, which comprises the following steps:
firstly, establishing a three-dimensional model and a substance model of microscopic particles, and manufacturing a microscopic particle model animation and an identification card, wherein the identification card is in corresponding relation with the three-dimensional model and the substance model of the microscopic particles, the microscopic particle model animation comprises a rotational animation of the microscopic particle model, and further comprises a microscopic particle model moving animation and a substance animation formed by combining the microscopic particles;
the identification card is mainly changed from the periodic table of elements, and the element name pinyin and the element out-of-core electrons are added on the basis of the original main atomic numbers, element symbols, element names and relative atomic masses of the periodic table of elements. Through the card, an experimenter can have preliminary knowledge of chemical atoms or ions, and partial atoms and ions can be quickly identified and remembered.
Atomic cards are exemplified by oxygen atomic cards. To distinguish the same atom, two kinds of cards were designed, the first was blue-green in background color, the letter parts of "8", "O", "oxygen", "2P22P4", "16.00", and "y +" were made with letter tools, the element extra-nuclear electronic patterns were drawn with round tools and rotary tools, the letter parts and the element extra-nuclear electronic patterns were both white in color, and in order to give the cards a hierarchical feel, only the letter transparency of "oxygen" and "y +" was 100%, and the other transparency was 80%. Besides the use of the element core and the text part, the electronic graph is also used for background and the details of the card are added.
For distinguishing, an ion card is also manufactured, the ion card is basically similar to an atomic card, an atomic symbol is changed into an ion symbol, an atomic structure diagram is used for replacing the number of out-of-core electrons, the relative atomic mass is removed, the background is kept unchanged, and the number of electrons above is reduced or increased according to the obtained electrons or the lost electrons. Note that the background of the identification picture is selected to be white when the picture is exported, the transparent background cannot be selected, and the picture exported by selecting the transparent background cannot be put into Vuforia for use, and the final effect is shown in fig. 6 and 7.
The model is mainly a three-dimensional model and a substance model of microscopic particles required by the system. The specific table is shown below:
the atomic model refers to an atomic structure schematic diagram, the atomic nucleus and the outermost electron number are reserved, taking the example of manufacturing an oxygen atomic model, firstly, the frame rate in engineering setting is changed into 25 frames per second, the frame rate is not too low or too high, the continuity of the animation is affected due to the fact that the frame rate is too low, more pictures are stored due to the fact that the frame rate is too high, the occupied memory is large, and therefore, the animation in China is generally manufactured by 25 frames per second. Creating a sphere model by using a sphere object, adjusting parameters, copying the sphere model, selecting a cloning tool, placing the copied sphere model under the cloning tool, selecting a cloning mode as a radiation mode, wherein the number of clones is 6, the radius is 80cm, selecting an XZ plane on the plane, and adjusting a starting angle or an ending angle. Other atomic models are also the same fabrication process, except that the number of clones is changed. And finally, adding different color materials to the model, so that the distinction is convenient. The effect diagram is shown in fig. 8.
In order to distinguish from an atomic model, an ion model is basically all elements which retain an atomic structure schematic diagram, and a sphere object, a text object, a cloning tool, a wrapping tool and an extrusion tool are mainly used, wherein the wrapping tool is mainly used for enabling characters to be attached to the surface of the sphere.
Molecular and ionic compound species models were made mainly using Unity3D software. The material model mainly comprises a liquid material model, a gaseous material model and a solid material model, wherein the liquid material model mainly comprises H2O, cuCl solution and FeCl2 solution; the gaseous substance model mainly comprises NO2, F2, cl2 and Br2; the solid model mainly comprises NaCl, caO, cuO, feO; most of the material models are colored, so that the material models are convenient to distinguish and memorize.
(1) The liquid object model is manufactured by using the water effect of Unity. Clicking the assembly-report Package-Environment-water, selecting and importing, directly dragging the material of the water to the model, adjusting parameters, adding corresponding scripts, and adding dynamic sense to the model. If the Environment option does not exist, the Asset Store can be searched for Standard assets, and downloading and importing can be selected.
(2) The gaseous material model uses a Unity particle system. Firstly creating an empty object, clicking the empty object by a right button of a mouse, selecting Effects, clicking a Particle System to finish the introduction of a Particle System, and then adjusting parameters according to requirements, wherein the direction of Particle movement is to be upward, so that the value of GravityModifier is set to-1. And (5) adjusting the colors according to the different required colors, and completing the manufacture of different gas substance models.
(3) The solid substance model is manufactured in CINEMA4D software, an irregular object model is created, a replacement tool and a surface subdivision tool are used, and a concave-convex map and a replacement map are mainly added to the model, so that the surface of the model is roughened, and the model has concave-convex property and granular feel. The effect diagram is shown in fig. 9.
Atomic model animation is largely classified into initial animation and animation at the time of composition.
1. The initial animation is completed in CINEMA4D, the offset in the cloned object attribute is found, a key frame is played at the required position, the function curve of the offset animation is adjusted, and the key frame type is set from a spline type to a linear interpolation type. When the export is completed, the FBX format is selected and the animation is checked.
2. Animation in synthesis is completed in Unity, the FBX format derived from CINEMA4D is imported into Unity, a model is generated into a prefabricated body, the prefabricated body is selected, an Animation panel is called out by using a shortcut key Ctrl+6, the prefabricated body is unfolded, a clone is selected, the record is clicked to start, the zoom of the clone is started from 1, and the zoom is changed to 0 after a few frames, and at this time, the record is ended.
Step two, obtaining a card carrying a microscopic particle model and detecting the distance of the card carrying the model;
object movement is the most central function of the whole system interaction, and other AR interaction functions are realized based on the interaction function. The function mainly comprises card distance detection, automatic movement of objects and animation, and an array is used because one object can generate effects with a plurality of objects.
The user reduces the distance between two cards through moving, when the distance is smaller than the appointed distance, the object automatically moves to the target point of the other card, and when the distance is larger than the appointed distance after the object moves, the object automatically returns to the original position. The movement is used to simulate the forces required to build up the build-up material.
The positions of the two cards are obtained, then the distance between the two cards is calculated by utilizing a two-point distance formula, then the size of the appointed distance is set, and whether the distance is smaller than the appointed distance or not is judged, the cards move when the distance is smaller than the appointed distance, and the distance is not changed when the distance is larger than the appointed distance. Because the other card is a group of arrays, circulation is needed before the distance is judged, whether the arrays are empty or not is judged, whether the card is recognized or not is judged, and the recognized card and the other card are subjected to distance calculation. Since the formula of the distance between two points in the three-dimensional space is derived from the two-dimensional plane, the calculation principle of the formula between two points is shown in fig. 2, and the flow is shown in fig. 1.
Step three, detecting the distance of the card, and when the distance is smaller than the specified distance, automatically moving the object and generating animation changes of the movement and combination of the object, wherein the animation changes are specifically micro-particle model movement animations and substance animations formed by combining micro-particles; when the distance between the objects is pulled again after the objects are moved so that the distance is not smaller than the designated distance, the objects automatically return to the original positions and the rotation animation of the microscopic particle model is restored.
When the distance is smaller than the specified distance, the object can automatically move to the target and become a sub-object of the target point, and the process simulates the process of forming molecules (ionic compounds) by atoms (ions) and atoms (ions). When the distance between the objects is pulled again after the objects move, the objects automatically return to the original positions and the rotation animation is restored.
The object is automatically moved to the target point by using the starting point, the target point and the distance of the object moving every second, using the vector3.Movetoward method, and then the object is set as a sub-object of the target point, and moves along with the target point, so that when the other card is out of recognition, the following functions can still be operated normally. Since the target point is a set of arrays, it is necessary to perform loop first and then judge. The calculation principle of the vector3.MoveToward method is shown in fig. 4, and the flow is shown in fig. 3.
When an object moves to a destination point, if a certain substance can be formed, the corresponding substance can be displayed, so that an experimenter can realize that the substance is formed by microscopic particles. The delay effect is achieved by using the Invoke function, and the microscopic particles of the model of the substance appear after 3 seconds of movement to the target point. If the movement to the target point does not exceed 3 seconds, the material model does not appear and the model of the microscopic particles continues to be maintained.
After the atoms (ions) can synthesize molecules (ionic compounds), the pictures on the card are switched from the pictures originally representing the atoms (ions) to the pictures of the molecules (ionic compounds), and the model is kept corresponding to the pictures. The essence of the picture switching is in fact the transformation of the material, creating a cuboid model conforming to the size of the picture, adjusting the thickness to be as thin as possible, making it look like a plane, creating material balls for different pictures, and giving the material balls to the cuboid. And an array for declaring the Material type is used for storing the materials, declaring the Material component and acquiring, enabling the Material component to acquire the original picture Material, and when the atomic (ionic) combination is achieved, forming molecules (ionic compounds), wherein the Material in the picture is replaced by another Material ball in the Material array.
In addition, as the animation can add dynamic sense to the whole picture, the microscopic particle model which is recognized by the system is provided with the rotary animation, the animation can be changed in the process of moving to the target point, the rotary animation can be gradually absent, and the process of combining with other microscopic particles to form a substance is convenient to observe. The animation component for obtaining the object obtains the animation of the object, the animation of the Bool variable type is added, the initial animation of the model is false to the final animation, the final animation of the model is true to the initial animation, and the transition time of the animation is controlled by utilizing the cooperative program instead of enabling the object to be transited when the object starts to move.
The method also has a highlighting effect, so that the model generates the highlighting effect, and the simulated atoms or ions are combined to form substances, so that the method can attract the eyes of an experimenter. The method is concretely realized as follows: and judging whether other objects to be highlighted are sub-objects of the object on which the script is mounted, and highlighting the effect when the objects are all sub-objects. The realization process uses the Highlighting System de mo plug-in for displaying the highlight effect on the object, and the plug-in can rapidly realize the desired functional effect and reduce the realization difficulty. The model can be highlighted by associating the script and utilizing the results obtained by other scripts.
