Here is the dev test so far: http://www.allforthecode.co.uk/development/away3d/sphere_dev<http://www.allforthecode.co.uk/development/away3d/sphere_dev/index.html>
Still needs work but getting there, it now has: - Rotation on drag - dead zone 40px on x and y - Click rotate look at target using camera3D - Click target sceneXYZ face normal for cube tween to location - Owncanvas glow - Sphere with transparent placement png for cloud rotation nice little cpu killer, reload if the materials don't fully load, found this to be a tad unpredictable. Next up, put it all in a container, do the same with the container to allow items added to the surface of the sphere to be rotated instead of just the spheres... lol I didn't think of this while building it doh :p <http://www.allforthecode.co.uk/development/away3d/sphere_dev/index.html> On 13 July 2010 10:57, Michael Iv <[email protected]> wrote: > With some vector+ trig magic you can manage it.
