so many buttons.. thanks Big O

Hey, back again, testing the render_region stuff...

It works much nicer with linear tonemapping, but it's still only getting a small section of the specified region.

I rendered the whole scene for a minute or two (with .igi saving on), then resumed with the render_region enabled. (I'm assuming that's the way it's supposed to be used anyway...)

So, as you can see in the attached pic, the alpha has the right dimensions/position, but the region it was actually updating doesn't. If I'm not resuming, that section is just black...

kinda; for a numerical methods project last year i derived the coefficients for a fourth order spline interpolating filter that has O(h^5) convergence, so it's a small generalisation of the MN filters. one of the nice things about this procedure is that if you don't want it to be an exact interpolation spline, you have a free parameter which can be used for noise control (acts as a very selective bandpass filter, somewhat similar to the MN b-coefficient but more detail preserving).

you can see the result here (look at the top silhouette): http://lyc.deviantart.com/art/tundra-72898099

um....where does the 'splat' filter belong?
is this a system option/ renderer option ? or what...

Thank you Ono !!!

Hi Alex,
actually resuming with just a particular region doesn't work (it will give incorrect results)

Can someone please send me a scene or tell me the settings that are causing those weird edge artifacts that Lyc was seeing? thanks.

I think i also got those edges with the DOF test scene. I can't 100% confirm though cause I can't run Indigo where i am at the moment.

Ah, nvm, got it.

Ono: If you could come into irc sometime, that'd be nice... It'd make it easier to have these discussions/fix these problems...

Umm... I think it was working with the resume... it looked fine to me. Either way, It won't render the entire render_region, as I said. It misses some on the top and right edges. (I even have another render [not resumed...] to prove it again if I need to)

Replaced download link with link to new version 1.0.5.2 which fixes overflow bug (hopefully) spotted by Lyc

it was (hopefully) spotted by lyc?

Seems to be fixed, thanx! ;o))


take care
psor

That's what he meant, alex

thanks for the fix
