【摘要】 为提高实时大批量目标符号绘制速度,提出基于GPU的高速标绘技术,使用CPU把大批量目标的属性数据传递给GPU,基于GPU的并行计算能力,使用顶点着色器和片段着色器,直接把每个目标的属性信息转换为对应的符号绘制。实际工程应用结果表明,随着目标数量的增多,高速标绘技术的绘制效率显著提高。更多还原

【Abstract】 In this paper, a real-time plotting method for massive targets is presented, which can be used to dramatically improve the speed of drawing symbols on the screen. The attribute data of massive targets is sent from CPU to GPU at first. Based on GPU parallel computing capability, the rendering of targets’ attributes is directly implemented at vertex shaders and fragment shaders of GPU. The experimental results show that the method based on GPU plotting technology is to be more efficient as the number of targets increases.更多还原
