Umajin 1.7 has a lot of new 3D capability, here is an example of exploiting it using JavaScript. This shows creating a sphere, texturing and rotating it. Loading a complex animated 3D model and triggering a new animation on completion. Then loading, positioning and rotating a static 3D model of a ladybird.
This really opens up the ability to create and share amazing interactions and games with the new 1.7 plugin system.
3D performance and visual quality is really a focus for the 1.7 release. Here are some example models and animation running on device.
