Testimonials
Here’s a few examples of what people have been saying about OGRE:
Those three characteristics make me choose it and so far, after almost a year and a half, I have never regretted that decision. Ogre3D has helped us a lot by speeding up the prototyping phase, testing new techniques for the physics algorithms really quickly, and, as part of my Argo Engine, serving really well as the presentation module.”
When we looked at Ogre the bar was instantly raised, it easily fulfilled all our criteria and more. The clean, extensible, object oriented architecture was well suited to our needs. Some open source projects often consist of cryptic, un-maintainable, spaghetti code. The thing I like most about Ogre, is that I do not feel compelled to have a shower every time I touch the code.
In addition, creating the scripts for interface components is a breeze since Ogre’s approach is clean and straight-forward. While you can (and we did) manipulate GUI components through code for advanced effects, it is easy to get GUIs up and running quickly. Ogre’s well-documented design makes it great both for prototyping and for customization of a finished product.
As an accolade to it’s stability, it has performed outstandingly in an embedded environment. The transparent portability has allowed the development under a Microsoft environment and subsequent deployment on Linux with painless ease. With constant ongoing development in a growing, and evermore supportive, community, we have visions of using this engine for many years to come.
