High-performance frustum clipping is offloaded to the GPU using ComputeShader logic and indirect drawing to bypass CPU-GPU data transfers. This system utilizes a C# manager to handle buffer lifecycle and a specialized shader for rendering clipped geometry.

1. Attach your camera movement script to the main Camera to track transform.hasChanged for frustum updates.
2. In your mesh clipping manager, initialize ComputeBuffer objects for vertices, UVs, and the triangleBuffer.
3. Calculate frustum planes using GeometryUtility.CalculateFrustumPlanes and pass them to the ComputeShader as a Vector4 array.
4. Dispatch the ComputeShader kernel to perform Sutherland-Hodgman clipping on each mesh triangle.
5. Append valid clipped triangles to the triangleBuffer and update the indirect arguments buffer.
6. Use Graphics.DrawProceduralIndirectNow in OnRenderObject to draw the processed geometry directly from GPU memory.

Additional Tips:

• Use ComputeBufferType.Append for the triangleBuffer to allow the GPU to dynamically determine the output count.
• Optimize performance by caching the camera frustum planes and only re-dispatching the ComputeShader when the camera or object moves.
• Ensure your rendering shader uses SV_VertexID to fetch triangle data from the structured triangleBuffer.
