Some rants on SMELT, QMidiPlayer and Virtools

+Well, I have to admit that creating a new blog post but not writing the +actual content until more than a month later is bullshit. I've +almost forgotten what I was thinking about when I created the post... +

+

+But as you can tell from my recent activity, development of QMidiPlayer +seemed to be stalled. No new features has been added since the rewrite +of the MIDI mapper. However the rewrite is actually for the next planned +major feature: an OPL3 emulator plugin and probably a VST host plugin. +I spent one third of my winter break on reading the specs of the YMF262 +chip but made no real progress, which is a real shame. +

+

+As for SMELT, I ported it to OpenGL 3.3+ but this is definitely not in +my original schedule. The initial port has a whole bunch of bugs and +quirks, also its performance was poor. Most of these were fixed later on +with the help of apitrace. +However currently the new port still makes way more OpenGL calls than +expected. +

+

+Planned features for SMELT include vertex array switching, material, +lighting and custom shaders. Adding these features will likely make the +older version deprecated though. Plus there's no strong demand for these +features. Therefore they may not be added any time soon. +

+

+The Virtools part is an entirely accident. 2jjy and I suddenly got excited +with the Virtools SDK and decided to find out what can it achieve. Before +long 2jjy managed to analyze the internal structure of a Virtools +behavior. These data determines how the behavior graph is presented +in the schemetic interface. Checking 'hide script representation in +schemetic' while saving simply discards these data, effectively obfuscating +the script. The final tool we made public reconstructs the base of this +structure using the logic of the script and tries to arrange behavior +building blocks in a more human-readable way. It definitely helps future +analysis of our old pal (Ballance), but not so much in my opinion. Porting +the custom DLLs used by Ballance to a "newer" Virtools verion might be way +more important. +

+

+The tool has been +made public. +As the job it does falls into a "grey zone", we don't know whether it is +legally acceptable to use it. Use at your own risk! +
