i am interested in Unity because it can play in a browser, on an iPad, and on Android
apart from that, i have little inclination to start creating in Unity because, in my opinion, it makes it harder to do virtual worlds. easier accessibility is clearly the advantage that Unity has, however, OpenSim is far more approachable
my personal “acid test” for this and to demonstrate what i mean by “more approachable” is to ask how long would it take to get a 12 year old to the point where they can create a house in a 3D space. i know what it takes to learn Blender (great tool but steep learning curve) and in OpenSim i can teach someone how to make a house in an hour, including textures and scripting a door (cut and paste, but they still get a door)
OpenSim will be my choice for a while as far as having a way for kids to create BUT . . . Unity may be the choice for sharing what i have built in conjunction with subQuark’s book. his project is about virtual field trips and not about teaching anyone how to build. for that purpose, Unity seems to be the only viable browser-based option and a very good one performance-wise
to be fair to Unity and Tipodean, i wanted to post a video showing the quality settings that redsolarmoon, Chris Collins, and Eurominuteman educated me about (the video below was made from Tipodean OpenSim conversion this demo - boys sure do love guns!)
the video shows how the user can set their own quality settings (hit Esc) and the overhead difference on the CPU is minimal – my Task Manager went from 22% on the lowest setting to only 29% on the highest!
the quality of textures, lighting, and shadows do change but i still see some edges not getting anti-aliasing applied – it is a minor thing for being browser-based but still one that i hone in on and is shown in the full size of the static image on the left
overall, i am very impressed with this and with it as a possible means to do the virtual component of subQuark’s field trips for Enclave Harbour
