Re: relief/parallax mapping

Heyas Gene,

 

Ive been playing with normal/parallax and displacements for the past 2 week at work for a near future job and i got the parallax shader working. it works great, especially with zbump plugged on normal. i couldnt get it to work with the normalmap node on (xsi's)  It is thou, a bit slow but there is no comparsion between it and normal maps. parallax is much much better. In one shot i tested them i can say that displacements are faster than the parallax thou but not in all cases it will all depend on the light you have plugged in.

 

Its the best reference model isnt it? having all the models in your scene actually being images in ultra low geometry. replace the image and you have a new model on:)

 

allright mate see ya soon:)

 

Saludos

 

Mario

Yeah that's the parallax shader I was referring to. Relief mapping is different btw... http://www.infiscape.com/doc/parallax_mapping.pdf

I finally got a little time last night to play with that shader and I can't seem to get it to work. Anyone have any success? I also played with the relief mapping plugin for max and I must say that it's pretty damn nice. Fast too.

your relief example below looks exactly like parallax mapping to me.

there's some small thingies with it, but overall Im very impressed with what this can do.

Subject: relief/parallax mapping

I was talking with a friend about this today (yes I know it's Christmas eve) and started wondering if there are any technical differences between relief and parallax shaders. Maybe I'm way off but I've been under the impression that they are one in the same, just with different names. I'm probably behind in my learning with this so feel free to slap me with the old school stick. I need to do some testing with the parallax shader anyway.

FYI... http://www.chaosgroup.com/forum/phpBB2/viewtopic.php?t=13906

Check out the difference between these two.
