Dent And Errode Top


RickWork

Recommended Posts

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,

We're running into legacy territory here. 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.

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:

As I remember it the erode TOP was basically a noise pattern which was clamped and the black bits made transparent.

Thanks Simon.

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.

I'm glad Simon could help you with that errode buisness, because I couldn't remember what that was suppose to look like. 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

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.
