Unity3d or virtools, which is easy to learn? Which one has a good future?

Virtools (VT for short): French heavyweight engine, which is designated by the World Expo, and its weight can be stated. VT was originally defined as a game engine (balance ball played, VT's works), and later mainly made virtual reality. VT has good expansibility, can customize functions (as long as it can program), can connect peripheral hardware (including vr-platform), has its own physical engine, and can interact almost omnipotent. The production is similar to WF or EON, but its modules are very detailed, so it can have great freedom and support Shader (although there are restrictions), and the effect is very good. He can create works in any field. Because the network plug-in has function restrictions, if it is put on the network, the function production will be slightly limited, but it doesn't matter if it is a single machine.

Unity3D (U3D for short): A rising star of virtual reality, paved by several previous big brother engines, U3D was defined as a high-end large engine from the beginning, which attracted wide attention in the industry. At first, it could only run on Mac system, and later it was extended to Windows system. What is commendable is that it is free (not for personal use). U3D comes with a lot of tools, making it easy. Interaction is also omnipotent, but there is no module, and the functions are almost all based on code, so you should have a good programming language, which also limits a large number of groups, and the picture effect is better than Q3D. In addition, he can easily link to the database, so that he can do some multi-person online work. Generally speaking, like VT, he can make works in any field.

Unity3d is recommended.
