摘　　要：由于现有的调度及渲染方法帧率低、空间占有程度高,为此,研究电网三维模型点对点分层快速调度及渲染算法。使用建模技术对原始电网模型进行结构解析,运用半边折叠算法对模型进行简化处理,获得一种连续的LOD模型。运用分块索引技术划分优化后的电网三维模型,使得每个区块都有唯一的索引,用于在需要时进行加载和渲染。通过控制模型载入量来提高调度效率,建立渲染分辨函数。利用GPU流处理技术将需要计算处理的顶点数据传输到着色器中,从而实现电网三维模型的渲染。结果表明,通过10次渲染实验后,其帧率均达到100 fps以上;5个小组空间占有率为20%~24.6%,符合预期目标,降低了渲染过程的复杂程度,满足了渲染需求。Due to the low frame rate and high space occupation of the existing scheduling and rendering methods,a point-to-point hierarchical fast scheduling and rendering algorithm for three-dimensional power grid models is studied.The original power grid model is analyzed by using modeling technology,and the model is simplified by using half-folding algorithm to obtain a continuous LOD model.The optimized three-dimensional model of power grid is divided by block index technology,so that each block has a unique index for loading and rendering when necessary.By controlling the model load,the scheduling efficiency is improved and the rendering resolution function is established.Using GPU stream processing technology,the vertex data that need to be calculated and processed are transmitted to the shader,so as to realize the rendering of the three-dimensional model of the power grid.The results show that the frame rate is above 100 fps after 10 rendering experiments.The space occupation rate of the five groups is 20%~24.6%,which meets the expected goal,reduces the complexity of the rendering process and satisfies the rendering requirements.
