for development of interactive 3d web applications, which engine is recommended? I am aware that WebGL has been anounced to become standarized for all browsers in the near future (1~2 years). I am afraid that by investing time into a proprietary game engine such as Unity, torque would be not great once plugin-less open source 3d engines appear (webgl & 3D javascript). Is this a stupid thing to worry about ? Should I begin with Unity3D (it's demo's and tools were mind blowing).
