Second, the library display module end
1. Display module for simulating three-dimensional effect
Mainly include indoor 3D effect display module, indoor article show module:
a) indoor 3D effect display module: the module shows the 3D effect of the library according to the designed attributes such as the shape point position, the size, the wall and the ceiling of the 2D library and a conversion algorithm, and a user can select to view indoor conditions from 4 angles by switching directions.
Specifically, in the present embodiment, switching angles is supported to view an indoor scene.
Conditions for support angle switching:
the first condition is as follows: the object plane picture and the 3D picture are respectively made and provide pictures in 4 directions of transverse direction, longitudinal direction, forward direction and backward direction;
and a second condition: when objects such as a bookshelf, a bookcase table and a chair are placed indoors by using the object layout device, data such as the coordinate position and the orientation (one of 4 directions) of the objects are recorded.
As shown in fig. 7, g1, g2, g3 and g4 are 4 corners of the top of the object BS1, s1, s2, s3 and s4 are 4 corners of the top of the object BS2, g1 of the object BS1 and s1 of the object BS2 which are currently displayed are opposite to the user, when the user switches to the diagonal direction, the system switches the point shape of the 3D library floor to the point shape when the user looks at the diagonal according to the switching instruction, replaces the 3D picture of the BS1 with the 3D picture of which the g3 corner is displayed as the front side, replaces the 3D picture of the BS2 with the 3D picture of which the s3 corner is displayed as the front side, and replaces the pictures of the wall and the ceiling in the corresponding directions, so as to realize that the viewing angle is switched to the diagonal, the switching process of switching to the other direction angles is similar in principle.
b) Indoor article show module: the module comprises two parts: 1. and displaying the 3D pictures corresponding to the objects at the positions appointed by the object layout device according to indoor 2D layout data designed by the object layout device, and calculating the precedence hierarchical relationship among the object pictures according to the coordinates of the objects and the occupation using hierarchical relationship to achieve a visual 3D effect.
Size calculation of 2D (two-dimensional) picture of object in I and 2D scenes
The size of the 2D picture presentation can be calculated relative to a grid (the grid is square) assuming that the side length of the grid is 1, one side length representing 30 cm.
Suppose a bookshelf has a length of 120cm, a width of 50cm and a height of 160 cm. The display width (relative to the grid) of this bookshelf 2D picture is then: 50/30, the length of the grid is 1.67, and the display length of the 2D picture on the bookshelf is: 120/30 is 4 grid sides long.
II, calculating the display size of the 3D picture of the object in the 3D scene
As shown in fig. 8, the size of the 3D picture of the object should be the size of the Q1Q2Q3Q4 rectangle, and it is Q1Q4 (picture width), Q1Q2 (picture height) that needs to be calculated. The l (length), D (width), h (height) of the object are known, according to the 2D/3D conversion settings: A. the B angle is known.
Calculating the formula:
picture width Q1Q4 ═ d × cos (a) + l × cos (b);
picture height Q1Q2 ═ d × sin (a) + h + l × sin (b).
III, calculating the display position of the 3D picture of the object in the 3D scene
As shown in fig. 8, the rectangle marked by P1P2P3P4 is a 3D scene display canvas (the coordinate origin of the canvas may be P1 or P2 or P3 or P4), the object 3D picture is a Q1Q2Q3Q4 rectangle, and the display position of the object 3D picture should be the coordinate position of the picture relative to the canvas origin. The l (length), D (width), h (height) of the object are known, according to the 2D/3D conversion settings: A. the B angle is known, assuming that the lengths of the 4 sides of the grid are all 30cm, the length of the H1H2 position is known, and the length of the H2H3 position is known.
Assuming that P1 is used as the origin of coordinates, the coordinate position of the picture Q2 relative to P1 is the picture display position, and the calculation formula is as follows:
q2 coordinates (X, Y):
X＝H1H2×cos(A)-d×cos(A)；
Y＝d×sin(A)+h+l×sin(B)+30×sin(B)+30×sin(A)。
IV, processing the precedence hierarchy relationship of the 3D pictures of the indoor objects
In a 3D effect display scene, all objects in the scene need to be calculated according to the overlooking plane shape and position occupation of the objects to calculate the front-back relationship (which object is displayed in front of and which object is displayed behind) of all objects, and the objects can be stored in a queue, and when the 3D scene is displayed, a 3D picture of each object needs to be displayed according to the calculated front-back relationship (i.e. the display sequence of the objects) of the objects, so as to achieve the object hierarchical relationship displayed by a 3D view.
2. In the process of remote viewing by a user of the 2D/3D effect switching module, the switching of the 2D/3D display effect can be realized by switching the view mode.
Switching from 2D to 3D: hiding or clearing 2D object pictures, grids and the like on the canvas, and presenting 3D grids, backgrounds, wall pictures, 3D object pictures and the like according to a 3D algorithm.
Switching from 3D to 2D: hiding or clearing 3D grids, backgrounds, wall pictures, 3D object pictures and the like on the canvas, and presenting the 2D grids, the 2D object pictures and the like according to a 2D algorithm.
3. The bookshelf effect display module displays side pictures of all books on the bookshelf according to book data placed on the bookshelf by the bookshelf placement layout device, so that a user can conveniently view the side pictures, brief introduction, value-added resources and the like of a certain book in a proper area when the user selects the book, and the user can view the brief introduction or electronic contents of the book.
4. All objects in the indoor view can be enlarged or reduced according to the need
In order to achieve the purpose that the object can be clearly viewed by zooming in or the object can be reduced to enable the object displayed in the interface to be more, a user can use a middle rolling key (rolling is performed in a mode of zooming in and zooming out, and vice versa) of a mouse or an interface button to send an instruction of zooming in and zooming out to the 2D or 3D view display canvas, so that the view display canvas is zoomed in or zoomed out according to a certain proportion, all the graphs and pictures in the view display canvas are automatically zoomed in or zoomed out according to a certain proportion along with the size of the canvas, and the purpose that the object in the view can be zoomed in or zoomed out according to needs is achieved.
