Oldschool effect name question
category: general [glöplog]
I need the name for the effect of the oldschool tunnels and distortions, you know the look up tables for x and y 2d displacement over a texture.
I suppose "2D displacement map" could be a good name for it, but as far as I remember, there is a more propper name. Do you remember it?
Thanks in advance

"offset-effect" ?
  
hmm. "movetable" effect ?
  
Table effect?
  
JSYK, in SVG they call them displace effect/filter.
  
+1 for "table effect".
  
first you give a good answer yourself
"2d displacement map", which is about exactly what it is
and then you people say table effect, 'movetable' effect or 'offset-effect' is more descriptive?
go to hell

offsetmap
  
movetable is the most common term I've heard at least.

That apparently was not boring enough to be used in shitload of Atari demos. ;)
we called all similar effects "színesforgó", which roughly means "colorful rotating stuff" 
  
I used "deformation matrix" at the time.
  
static texturemapper
  
grid effect?
  
i call them "bernard".
  
it was called "your mum".
  
you don't store x and y 2d displacement over a texture, you store the offset in that texture and use addressing modes to pass in the base address of the texture.
that's why i call it an offsetmap, because it store offsets, and because it's a map, like in pixmap and bitmap.

you are confused, that was the "pretty cool mid90s atari effect" :-)
back in the days, we called that effect "analraid" for obvious reasons :-)
  
offsetmap: a boring old effect, for which you need to be called tobe to use it effectively.
