Hopefully, S3 is more concerned about licensing to the hardware manufacturers than driver vendors. In the DRI drivers, using a compressed textures will be little more than specifying a new register value to indicate the compressed format. In software, it's just an implementation of the algorithm spelt out in the OpenGL extension specification. It's hardly a secret technique. > So instead I would hope that ATI (or > possibly S3) would provide a closed-source binary module to add S3 > Texture Compression to the Radeon / all DRI drivers. > Is this possible?

And since the algorithms are public, anyone could go and re-implement the binary module. So, it would be kind of pointless. -Brian ------------------------------------------------------- This sf.net email is sponsored by:ThinkGeek Welcome to geek heaven. http://thinkgeek.com/sf _______________________________________________ Dri-devel mailing list [EMAIL PROTECTED] https://lists.sourceforge.net/lists/listinfo/dri-devel
