Abstract

The invention provides a display device and a firework animation special effect drawing method, and the method comprises the steps: dynamically creating an explosion position of a firework animation special effect through responding to a control instruction, and selecting an initial speed and a direction angle of firework particles in a preset initial speed range and a direction angle range; the center point coordinates of different time nodes are calculated in real time through a preset curve mathematical model, then a normal vector is generated based on direction vectors of two continuous center point coordinates, a firework path is divided into a plurality of firework path segments through the normal vector, and finally the firework path segments are drawn according to the path sequence to display animations. According to the method, by controlling parameter conditions such as the initial speed, the direction angle and the curve model, different firework paths can be generated when the firework animation effect is played every time, and the randomness and the dynamic adjustment flexibility of the firework animation effect are improved.
