Hi all,
I am reasonably new to shaders. I intend to implement a floating point
lookup table. The aim is to write a fragment shader that takes an in coming RGB
Color, Lookup a floating value from the table and write it to the frame buffer
pixel. I tried using a GL_FLOAT type 1-D LUMINANCE texture and accessing
it using a sampler, followed by GL_FLOAT type 1-D RGB texture, but both of them
put up a blank screen.
Thereafter, I tried to declare a varying float Array in the vertex shader
and computed it there and used the values in the fragment shader. But now I get
the following error:
** error C5041: cannot locate suitable resource to bind parameter "<null
atom>" **
Please help.
Regards
Harash
