Embodiment Construction
[0021] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0022] see figure 1 As shown, the embodiment of the present invention provides a method for quickly drawing multiple curves, including the following steps: selectively calculate the actual drawing points of the curve without greatly affecting the drawing accuracy, and after determining a reasonable initial value, Dynamically adjust the interval value of the actual drawing points according to the calculation results, which can reduce the calculation number of drawing points and thus improve the drawing speed. The specific process is as follows:
[0023] S1. Calculate the length sum of all line segments according to the order of the starting point, middle point, and end point of the curve, and obtain the inverse number as the initial value of the interval value of the actual drawing point of the curve to be drawn;
[0024] S2. The form...
