Revolver has released in the last week, a Beta version of FreeSpin 3D which is completely free. This component is based on their OL3D technology. There are some good features i see in this component that worths to be mentioned, such as the ability to support in near future any 3d model (currently beta, just supports .3ds). The way that models are imported to the library, is also a good point, as it contributes to a faster application development. This component was made not only for developers but also to designers, as to implement 3D content into a flash movie, doesn’t means you will need to use any code on it, just depends on your needs or skills.
I liked what i’ve read and seen. It is definitely a component to bear in mind each time we want to produce 3d content within our flash projects.
