Average polygons in architectural visualization

[josem1]

I am wonder what is the average of polygons in a architectural scene, and what is the average of render time per frame (please explain your image size.)

 

I am working with a scene with 7,426,071 polygons.

Rendering time per frame is 161 minutes at 1920 x 1080 pixels.

 

Thanks, Jose

That depends on what it is...the more polygons the longer render time...no avarage polys in any scene, but lower is faster.

You will quickly discover there is no formula. If you have 5000 polys of a stack of diamonds, it will take longer than a scene consisting of a 7 million poly city made of paper. Your result depends on how hard the cpu has to think and there are endless methods for optimization.

Considering we don't know your PC specs or your render settings, it's incredibly hard to pinpoint numbers. However, 161 minutes for a 1080 frame seems way too excessive for my tastes.

 

What's considered an average architecture scene? For us, since we do arenas and large scale sports complexes, average for us is well into the millions of polygons. For a home? That could be a lot less. For a home with well sculpted furniture? Could be a lot more polygons that we even use. Architecture is way too broad of a subject to draw averages. You need to define a specific subset of architect. But even then, depending on your won personal tastes and your tolerance for chunky looking low poly objects, your polygon count will still vary wildly.

 

To top it off, low poly doesn't always mean low render time. I can make a single cube render 100 times longer than a scene with 6 million unique and turbo smoothed cubes if I screw up my material/lights/camera/render settings.

I am currently rendering 3400 frames @ 1080p for a casino interior with about 100 million polygons. I spent 3 days getting the render times down to ~50 mins per frame for the more complex areas and the more simple zones at about ~30. All comes down to aliasing in the end, balancing noise against time. DonoiserII (Red Giant) has been a great help. I rendered the whole thing over night on Rebus and swallowed the cost. Would have taken 8 days on my own hardware, 5 hrs online.
