Heightmap in Shader VS_Model 2.0

vvvv beta question
1

hello there.

We are working with the heightmap displacement shader from deaxismundi heightmap-displacement, which is awesome.
but our final hardware will be a bit old and doesn’t support shader model 3.
From what I see (shader newbie), the tex2dlod gets the color values from the incoming texture in the vertexshader.

is there something like this, that does this in vs_shader model 2?

thanks a lot.

what kalle said.

(vertex texture fetch is a sm 3.0 feature afaik)

pleeease…
