Pixel Processor and sequenced lerps

bugo

Hey guys,

Got a quick question for the SD master minds.

On Pixel processor, I want to basically use the uvs of a normal map (whatever one) and push pixels in a sequence, and lerp one next to another, using max, min, whatever. Any chance I can get help from someone?

It's basically like the slope blur, but I want to experiment with this on the pixel processor and add some more things to it.

Thanks again,
Hugo

Here's an example of what im trying to do, but if I could have a sequence, I could add maaaany more instead of manually add each.

Hey,
As the pixel are processed in parallel, you can only change the value of the processed pixel.
therefore (if I understood correctly),
For each pixel I would scan the 8 pixels around, get the value of each red and green channels,
and do some maths to know from which pixel it should inherit the value.

LOL - yup Vincent and I just ran into this man. We were hoping it evaluated per pixel not in parallel - but alas we were wrong.

Would love to see an improved slope blur! Good luck and please let us keep us updated!

I just made a pixel processor function that also could have benefited from a loop. To simplify things I built the functions up in blocks of 32 pixels each and multiplied each variable in the block by the block number. This means for a 512 pixel wide image I only needed 16 blocks. For my function I only had 1 variable and 2 or 3 connections that needed to be set per block.
