[osg-users] shader in OSG

[杨光]

*I want to pass a two-dimensional array into the shader. Is this difficult 
to do? If this is not possible, in what form should this information be 
passed to the shader? Can this information be stored in a picture as a 
texture and passed to the shader, if so, how can the information in the 
texture be read out in the shader? thank you very much*
