Inara is covering the update of the Black Dragon Viewer for Second Life™, version 18.104.22.168. See: Black Dragon 22.214.171.124: snapshot floater and cinematic camera.
The effect of the new Cinematic/Head Tracking Camera is shown in the video. I would have to play with the camera to see if I like it and think it useable, which has nothing to do with whether it is or isn’t. The effect in the video is pretty neat.
I may have to try it to see how it works with the SpaceNavigator, which uses flycam mode when controlling the camera..
NiranV is working on the viewer’s snapshot panel. NiranV designed the panel that appears in the SL Viewer distributed by the Lab. In NiranV’s viewer the panel is apparently evolving. That is S.O.P. for NiranV, which is the reason I like the Black Dragon Viewer but don’t use it. I like the innovation. I hate continually having to figure out how things work or what controls have moved to where with each update.
It isn’t as bad as I may make it sound. I think everyone that takes pictures or makes machinima in SL should try the viewer.
