Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
In order to solve technical problems in the related art, embodiments of the present invention provide a polygon rendering method, an apparatus, an electronic device, and a readable storage medium.
The electronic device may perform the method steps of the polygon rendering method provided by the embodiment of the present invention. The electronic devices include, but are not limited to, computers, smart phones, and smart wearable devices.
In addition, office software can be installed in the electronic equipment, and a user can draw a graph through a drawing tool in the office software. The office software includes but is not limited to: word software, PPT (PowerPoint, presentation) software, and WPS (WPS software).
Referring to fig. 1, a polygon rendering method provided by an embodiment of the present invention may include the following steps:
s101: determining the number of edges of a first graph drawn by a user through a polygon tool;
when a user wants to draw a polygon with a specified side length, the user can draw a first graph by using a polygon tool. For example, the user may draw a resulting hexagon as the first graphic using a hexagon tool.
The electronic device may then determine the number of edges of the first graphic. For example, the electronic device may determine that the number of edges of the first pattern drawn by the hexagon tool is 6.
The electronic device may record a mapping relationship between the polygon tool and the number of edges. In this way, after the user draws the first graphic through the polygon tool, the electronic device may determine the number of edges corresponding to the polygon tool according to the mapping relationship, so as to determine the number of edges of the first graphic drawn through the polygon tool.
Of course, a margin input box may also be displayed. In this way, it is reasonable that the user can input the number of edges of the first graphic in this edge number input box, so that the electronic device can obtain the number of edges of the first graphic.
In addition, it can be understood that when the user selects the polygon tool and draws the polygon by dragging the mouse, the side length of the drawn polygon is not always the side length desired by the user. For example, a user wants to draw a hexagon with all sides of 5 cm, but the drawn first graph has each side with a length of 5 cm and is different from each other.
S102: obtaining the side length to be set for the first graph input by a user;
wherein, the electronic equipment can display a side length input box. The user may input a value of the side length the user wants to set for the first graphic in the side length input box. The electronic device, after obtaining the value, may determine the value as a side length to be set for the first graphic.
For example, the user may enter, within a side length input box: the user wants to set a value of 5 cm for each side length for the hexagon.
S103: calculating the height and width of the polygon meeting the number of edges and the side length;
for example, the number of edges obtained may be 6, and the length of the edges obtained may be 5 cm. After obtaining the number of sides and the side length, the electronic device may input the side length and the number of sides to a circumscribed circle radius calculation formula. Thus, the radius of the circumscribed circle of the polygon satisfying the number of sides and the side length can be calculated.
Wherein, the circumscribed circle radius calculation formula can be:
wherein r is the radius of the circumscribed circle of the polygon, l is the side length input by the user, and n is the number of sides of the first graph.
After calculating the radius of the circumscribed circle of the polygon, the electronic device may input the number of edges of the first graph and the radius to a height calculation formula. Thus, the height of the polygon can be calculated. Wherein, the height calculation formula is as follows:
where h is the height of the polygon and mod is the remainder operator.
In addition, when the determined number of edges is an odd number, the electronic device may input the number of edges and the calculated radius to the first width calculation formula. Therefore, the polygon which is externally connected with the circumscribed circle and satisfies the width of the polygon with odd number of sides; wherein the first width calculation formula is:
wherein, w1The width of the polygon calculated when the number of sides is odd.
When the number of sides is an even number, the width of the polygon may be calculated by inputting the number of sides, the radius, and the height to the second width calculation formula. Therefore, the width of the polygon which can be circumscribed to the circumscribed circle and satisfies the even number of sides can be directly calculated based on the second width calculation formula. Wherein the second width calculation formula is:
wherein, w2The width of the polygon calculated when the number of sides is even.
In the above, the height and width of the polygon to be drawn may be calculated based on the number of sides and the length of the sides of the polygon to be drawn and the radius of the circumscribed circle. For example, the height h and width w of the hexagon to be drawn as shown in fig. 2 may be calculated. Wherein the hexagon can circumscribe a circumcircle with radius r.
S104: and adjusting the first graph by using the height and the width to obtain a polygon meeting the number of sides and the side length.
In particular, the first pattern may be adjusted to a pattern that conforms to the height and width. Then, the side length of the first graph can be adjusted to the specified side length input by the user, so that a polygon with the specified side length can be drawn.
When the number of the obtained edges is determined to be even, obtaining a polygon to be drawn by the following method:
the width and height of the first pattern are adjusted by using the height and width while keeping the number of edges of the first pattern constant. That is, the width and height of the first pattern are adjusted to satisfy the height and width, thereby obtaining the second pattern.
And then, under the condition of keeping the number of sides and the width and the height of the second graph unchanged, setting the side length of each side of the second graph as the side length input by a user and setting the angle of each vertex angle of the second graph as equal to obtain a polygon. Thereafter, the polygon may be rendered and the first graphic replaced with the polygon.
Wherein, the side length of each side of the second graph is set as the side length input by the user and the angle of each vertex angle of the second graph is set as equal, and the polygon is obtained by the following steps:
and searching for the parameter information of the adjusting points which have a mapping relation with the edge number in a preset mapping table. And the adjusting point parameter information is parameter information used for adjusting the second graph. Then, the adjustment point of the second graph can be adjusted according to the adjustment point parameter information, so that the side length of each side of the second graph is the side length input by the user, and the angle of each vertex angle of the second graph is equal, thereby obtaining a polygon.
Wherein, the preset mapping table may specifically record: the mapping relationship between the number of edges six and the first adjustment point parameter information, and the mapping relationship between the number of edges eight and the second adjustment point parameter information are, of course, not limited thereto. Wherein the first adjustment point parameter information may be parameter information for adjusting the hexagon to a regular hexagon. The second adjustment point parameter information may be parameter information for adjusting the octagon to a regular octagon.
Wherein, the first adjusting point parameter information is:
the second adjustment point parameter information is:
the following explains the adjustment points provided by the embodiments of the present invention:
referring to fig. 3, the adjustment point is provided at the position of the upper left vertex of the hexagon shown in fig. 3. And the position of the adjustment point will change with the change of the parameter information of the adjustment point. Wherein one position of the adjustment point corresponds to one adjustment point parameter information. When the adjustment point parameter information of the second graph is set to 0.25/cos30 °, the hexagonal adjustment point may be located at a quarter of the long side of the rectangular dashed box shown in fig. 3, that is, the distance from the position of the adjustment point to the wide side of the rectangular dashed box is a quarter of the long side.
The adjustment point shown in fig. 3 may move left and right on the long side of the rectangular dashed frame where the adjustment point is located when the value of the adjustment point parameter information changes (where the rightmost position may move to the center of the long side). When the adjusting point moves leftwards for a preset distance, the point of the lower left vertex angle of the hexagon also moves leftwards for the preset distance horizontally, and the point of the upper right vertex angle and the point of the lower right vertex angle of the hexagon move rightwards for the preset distance horizontally. In addition, when the adjusting point moves rightwards for a preset distance, the point of the lower left corner of the hexagon also moves rightwards horizontally for the preset distance, and the point of the upper right corner and the point of the lower right corner of the hexagon move leftwards horizontally for the preset distance.
In an embodiment of the invention, the number of edges of a first graphic drawn by a user via a polygon tool may be determined. Also, the side length to be set for the first graphic input by the user may be obtained. Thereafter, the height and width of the polygon satisfying the number of sides and the side length may be calculated. Then, the first graph is adjusted by using the height and the width to obtain a polygon meeting the number of sides and the side length. In this way, the side length of the polygon obtained by drawing is the specified side length. Moreover, the polygon with the specified side length can be simply and quickly drawn.
In conclusion, by applying the polygon drawing scheme provided by the embodiment of the invention, the polygon with the specified side length can be simply and quickly drawn, and the user experience is improved.
