... from an anonymous commenter, some excellent questions. (I'll be
adding these to the FAQ).
This system is complementary to Truelight / Cinespace. AlthoughOne question I think would be good for the faq: how does this system
Truelight comes with a bunch of plugins, its core functionality is to
generate the 3D luts for things like print emulation, device mapping,
etc, and I don't see this role changing. (Our library does not
to fill these roles). It will be very straightforward to implement
reader for unencrypted truelight luts. Note that supporting
*encrypted* luts is probably not simple due to legal considerations.
am unsure if Cinespace has the capability to export un-encrypted LUTs.
Sorry for being confusing. ALL of the Cg / GLSL generation stuffAlso, I didn't totally get this line in the faq: "GPU Acceleration is
developed at SPI (related to color processing) is being included in
This entry was intended to clarify issues relating to integration;
even though this library generates cg / glsl code, we don't link to
GL directly. Instead, the library returns "simple" data types, a
std::string with the shader text, and a float* with the lookup
It is left to the client app to make the appropriate GL calls
accordingly. (which in our experience is not much of a burden, and
actually makes everyones lives simpler). A bit of extra information
(such as cacheIDs for the 3d luts) are also included to allow for
additional client-side optimizations. (In the 3dlut cacheid case, to
prevent reloading the 3d texture every time something changes).
