Shader texture lookup

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 ?


seems like it is possible :)

second question remains…

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

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

i can not find the thread
desax made a shader

Heighmap Displacement with (6.8 kB)

thanx for finding it ! that’s exactly the source i was looking for to get on with my shader experiment
