Shader texture lookup

vvvv beta question
#1

is it possible to do a texture lookup in a vvvv hlsl shader now ?

i remember, it wasn’t at some point.

i want to feed a grayscale texture into the shader and deform a grid according to the lightness of pixels. maybe someone has already done it ?

second question remains…

#3

there was a shader called “Displace” in the last vvvviki, i think.

and if i remember right this may NOT work on ATI cards

#4

i can not find the thread
but
desax made a shader

Heighmap Displacement with Normals.zip (6.8 kB)
