Question How to draw multiple polygons in groups?

I have sectors and in the sectors I draw groups of polygons.

I use Graphics.Draw to render polygons, but I want to draw after I determine if the polygons are visible or not.

Can there be one draw after shader clipping or how do you draw multiple polygons from groups?

I put in Graphics draw and material property block to clip and draw the polygon, is there a better way?

 

I would generate retained graphics data in the form of GameObjects, MeshFilters (with the Mesh) and MeshRenderers.

That way you can do 100% of anything that sits in a scene and gets stared at by Camera.

If you want simple examples of producing retained geometry, check out my MakeGeo project.
