topology | 程序化几何体的拓扑。 |
vertexCount | 要渲染的顶点数。 |
instanceCount | 要渲染的实例数。 |
在 GPU 上绘制程序化的几何形状。
DrawProceduralNow 在 GPU 上执行绘制调用,没有任何顶点或索引缓冲区。
主要适用于 Shader Model 4.5 级别的硬件,其中着色器可以从 ComputeBuffer 缓冲区
读取任意数据。
注意,该调用立即执行,类似于 Graphics.DrawMeshNow。它使用当前设置的渲染目标、变换矩阵和着色器通道。
CommandBuffers 中也有类似的功能,请参阅 CommandBuffer.DrawProcedural。
另请参阅:Graphics.DrawProceduralIndirectNow、SystemInfo.supportsInstancing。
