@chk:matrix.orgchkalso doing this right now like that, but also not so sure if its the most elegant solution19:00:46

@chk:matrix.orgchkfeels like an aweful lot to do, there must be better solutions19:17:00

@bj-rn:matrix.orgbj-rn Maybe not the most elegant but according to this it should be fast. 19:37:22

@bj-rn:matrix.orgbj-rn * Maybe not the most "elegant" but according to this it should be fast. 19:38:02

@CeeYaa:matrix.orgCeeYaa it's very elegant bj-rn in his way 19:39:01

@chk:matrix.orgchkalso another question - I am trying to apply a filter only to certain areas of a texture, and built for this a control texture with skia, that is fading random squares in a grid between black and something gray-ish (color value of 0.6). the control texture fades wonderfully and linearly, but the filter drags behind... does this relate to linear and srgb?19:39:16

sent an image.
This is using RandomSpread internally.

@chk:matrix.orgchkalso tried with a lineartosrgb node after the control texture, but this also does not look perfect19:40:26

@CeeYaa:matrix.orgCeeYaaI think the Blur Strength is not liniear - so you didn't see it in the white - maybe logarithmic - no shaderguy - just a gess19:56:07
@CeeYaa:matrix.orgCeeYaa * I think the Blur Strength is not liniear - so you didn't see it in the white - maybe logarithmic - no shaderguy - just a guess 19:56:23
@CeeYaa:matrix.orgCeeYaa * I think the Blur Strength is not liniear - so you didn't see it in the last values of the white color - maybe logarithmic - no shaderguy - just a guess 19:56:57
@CeeYaa:matrix.orgCeeYaa * I think the Blur Strength is not liniear - so you didn't see it in the last values of the white color - maybe logarithmic - no shaderguy - just a guess - maybe change the filter 19:57:57
@CeeYaa:matrix.orgCeeYaa * I think the Blur Strength is not liniear - so you didn't see it in the last values of the white color - maybe logarithmic - no shaderguy - just a guess - maybe change the filter - ah but you want a linear BlurStrenght transition ?! 19:58:47

@chk:matrix.orgchkcan it be that it is gammatolinear?20:01:06

Creating the control texture with skia sounds a bit slow. Just drawing quads or even just using a low res dynamic texture with point filter might be much faster.

@chk:matrix.orgchkyes, I can imagine, also thought about that. but in my case it is better to use skia, because I am collaborating with somebody who is more used to drawing with skia than with the stride pipeline.09:28:13
@chk:matrix.orgchkstill... this is not related to the initial problem, right?09:28:35
