Problems solved by technology

Using the above-mentioned existing technology, when the weather curve needs to be enlarged, because the weather curve is in the picture format, that is, the weather curve is composed of pixels, and the enlargement of the weather curve needs to be interpolated between the original adjacent pixels. method to add new pixels, when the image of the meteorological curve is enlarged to a certain extent, the presented meteorological curve continuously adds new pixels through interpolation between adjacent pixels, and the added new pixels do not It completely conforms to the trajectory of the meteorological curve, resulting in blurred or rough edges of the enlarged weather curve

Embodiment 1

[0071] refer to figure 1 , showing a flow chart of a method for creating a weather curve in the present invention, including:

[0072] Step 101, connecting the preset control points into a curve;

[0073] The user can select control points according to the weather trend, and connect the selected control points one by one to form a preliminary Bezier curve of the weather curve, that is, the control points are all on the weather curve. The advantage of this is that when making the weather curve animation, the animation effect of the weather curve can be realized by adjusting the control points, without the need to interpolate the weather curves one by one as in the prior art, so that Get an animation of the weather curve.

[0074] Step 102, selecting a first group of discrete points on the curve according to preset intervals;

[0075] Generally, the preset interval is set relatively short. The purpose of this is to make the connection between the discrete points coincide with...

Embodiment 2

[0086] This embodiment provides a method for constructing a triangle on a meteorological curve, and the method for acquiring the first and second discrete points mentioned in this embodiment is the same as that in Embodiment 1. see image 3 , constructing the triangle on the meteorological curve includes:

[0087] Step 301, selecting any point in the second group of discrete points as the first vertex of the basic triangle;

[0088] When implementing this step, the basic triangle is Figure 4 Triangle ABC shown in .

[0089] Step 302, select a point in the second group of discrete points as the second vertex of the basic triangle, the distance between the second vertex and the first vertex is the preset side length of the basic triangle;

[0090] In this embodiment, it is assumed that the preset side length of the basic triangle is exactly the distance between two discrete points in the second group of discrete points, that is to say, the first and second vertices are exact...

Embodiment 3

[0098] This embodiment provides a method for constructing an arc on a meteorological curve, and this embodiment is carried out on the basis of Embodiment 2. see Figure 5 , constructing the arc on the meteorological curve includes:

[0099] Step 501, make a semicircle with the distance between the first vertex A and the second vertex B of the basic triangle as the diameter, and the third vertex C of the basic triangle is on the made semicircle arc (see Figure 7 Give a schematic diagram of a triangular patch forming an arc on a curve)

[0100] Step 502, on the arc edge between the second vertex and the third vertex of the basic triangle, select a fifth group of discrete points at a preset distance, and the fifth group of discrete points includes B, c1...c8, C;

[0101] Step 503, every two adjacent points in the fifth group of discrete points and the second vertex of the basic triangle construct a triangular patch, and the discrete points adjacent to the third vertex of the b...

Abstract

The invention provides a method for creating a meteorological curve, comprising: connecting preset control points into a curve; selecting a first group of discrete points on the curve according to preset intervals; moving the selected first group of discrete points clockwise Or widen in the counterclockwise direction to obtain the second group of discrete points; construct a triangular patch with the first and second set of discrete points as vertices; integrate and render the constructed triangular patches to obtain a meteorological curve.

Description

technical field [0001] The invention relates to the technical field of animation, in particular to a method and device for creating weather curves. Background technique [0002] Weather lines such as cold fronts, warm fronts, stationary fronts, and solid fronts are often used in weather forecast systems, and the display of these curves directly affects the broadcasting effect of weather forecasts. In the prior art, various meteorological curves are often made into the format of pictures. When the weather forecast is broadcast, if the weather curves need to be used in the broadcast picture, the corresponding weather curve pictures will be prepared in advance. Place it at the corresponding position in the broadcast screen. Using the above-mentioned existing technology, when the weather curve needs to be enlarged, because the weather curve is in the picture format, that is, the weather curve is composed of pixels, and the enlargement of the weather curve needs to be interpolat...
