RickWork Posted February 11, 2006 Share Posted February 11, 2006 Hello, I'm going through one of the old pdf files (pop_fire) and towards the end it talks about getting a dent top and an errode top. What are these? Or rather, is there an equivilant shader to these in shops now? Cheers, /Rick Quote Link to comment Share on other sites More sharing options...

Tops( texture operators ) was a module that was discontinued as of version 4. Basically vex, vops and shops replaced tops. If you let me know what the shader needs to do I can probably tell you how to create it. Luca Quote Link to comment Share on other sites More sharing options...

Luca 24618[/snapback] Hi Luca, I guess the dent TOP is like the vex fractal dent SHOP? I don't know about the Errode though. To save on some typing, I have uploaded screen captures of the the pages that describe the TOPs here: http://www.rickw3d.com/DentTop.jpg http://www.rickw3d.com/ErrodeTop.jpg Cheers, /Rick Quote Link to comment Share on other sites More sharing options...
sibarrick Posted February 11, 2006 Share Posted February 11, 2006 As I remember it the erode TOP was basically a noise pattern which was clamped and the black bits made transparent. Quote Link to comment Share on other sites More sharing options...

How would I go abouts doing this in VOPS? I guess I can use an AA Noise VOP but i'm not too sure on how to make the black bits transparent.

As far as the alpha para and alpha perp I thought there was a vop that did this but I guess not. So make your own, you can use the dot product of "I" and "N" to control the alpha of your object. I can't remember what the "role off" controled but, maybe simon remembers. All the best Luca Quote Link to comment Share on other sites More sharing options...
sibarrick Posted February 13, 2006 Share Posted February 13, 2006 Well I don't remember exactly but rolloff is usually just a function applied to the output of the dot product to change way the values interpolate. If you are using Vops go with the alpha mix vop, everything is there for you. I bet its the same as the old tops would use. If you are rolling your own with the dot product vop then I would probably just follow it up with a smooth vop and use the rollof provided there. But you can also use a power vop and muck around with the exponent. Quote Link to comment Share on other sites More sharing options...
RickWork Posted February 13, 2006 Author Share Posted February 13, 2006 Thanks guys, I'm gonna work on these VOPs today. Yeah I found the alpha mix vop last night. Good stuff! Thanks! /Rick Quote Link to comment Share on other sites More sharing options...
