[GEM-dev] vertex displacement

[cyrille henry]

hello,

i investigate a bit more the vertex displacement problem.
so i've got a 8 bit texture that is rendered in a FLOAT framebuffer, in order to convert it to 32 bit.
then, the frambuffer texture is used in a shader to distord a primitive

i have to strangely mix mode 0 and mode 1 in the patch to make it work, and this is very ineficient (just like in 8bit mode).

framebuffer and fragment shader usually work in mode 0 and 1 on my computer.

see patch for more.

thanks to have a look.
using texture in vertex shader would be great...

thanks
Cyrille
