THE PLACE FOR ALL THINGS BRYCE - GOT A PROBLEM? YOU'VE COME TO THE RIGHT PLACE


Subject: Image resizing

It is a common practice in Terragen to render images over 3000x3000 and then resize, resample and sharpen. Does anybody do that in Bryce, especially images that aren't extremely complex? Terrage render times for these size images come in at a few hours to over 24 hours. Is there any advantage to doing something like this in Bryce or with all the anti-aliasing effects and such is it a waste of time?

I know a lot of people will render large and resize down. I just render to specifically what I want at the time, which is mostly just an upload to my gallery, so I'll render at 800x600/1024x768/etc.

If I don't need to render for magazine print or similar, why suffer through the long render times? (as I see it)

But...I DO remember reading in the notes of a Bryce render, of one of our fave Bryce artists, "hobbit", that he had rendered 3,000 pixels wide with NO AA, and then resized down to get a certain "look". (see link)

Also, in Bryce if you aren't using resizing techniques, and want a less soft look to something, we can select specific objects, and specify that, that object will not get anti-aliased (except for its edges) For example, this will help rocky surfaces stay "rocky" and not look too soft by AA. AS

Over sampling isn't as common as it use to be. To over sample a complex scene in B5 could take over 2 or more days even with AA turned off. If you haven't hear render time in Bryce is it's biggest downfall.

I don't remember when I started this render but I think it is entering its 24th hour. I will post it full size when it is finished. It doesn't look bad in the image provided but full size everything below the line is really jagged.

I also render to my end product destination and thats mostly for web viewing in which case I would render at either 72dpi or 96 dpi (depending on the intricacies of the textures used) and output to either 800x600 or 1024x768. For printing purposes I then crank up to 150dpi 3000x4500 and this can be very CPU intensive and time consuming. Ive gone for 2 weeks time without the use of the computer while waiting for the final render. Believe me, you can go mad waiting and often tempt the hand of fate when trying to sneak in some on-line multitasking and praying that nothing crashes. 8/

I haven't had Bryce very long but I have never had a problem with running out of resources. I do basic word-processing and surf the internet and play internet-based games while images are rendering all the time. I am typing this with it rendering right now. The only thing that even slightly bothers me is that the line doesn't show back up until it moves to the next row after I restore Bryce.

TobinLam - It's still rendering, not to worry. It literally is just Bryce waiting for the next line to refresh. Priorities.

When it finished sometime early this morning the summary said 58:27. Is that 58 minutes? I know it didn't go 58 hours. Wait, I just check the file properties and the last time it was modified was October 6 at 10:35, about the time I hit render I think. Maybe it did go for 58 hours, by far the longest I have ever rendered. I knew it was still rendering, the line always showed up a few minutes later. Thanks AgentSmith.

That should be 58 minutes, as long as it just says 58:27, and not 58:27:00, which would be 58 hours. Even scarier, when I ran Bryce on my old, snail slow computer, if I did the alt+ctrl+delete, during a Bryce render to disk, it would tell me that "Bryce is not responding" even though it really was still rendering.
