Transitioning Hidden Geometry?

Jim

As far as I know, Sketchup can not gradually transition hidden geometry, right? I mean, you can not gradually 'unhide' something - it is always either on or off? Would be a nice effect...

You are right.
However, you can mimic the fading - group the object(s), keep one as the base one, then copy it and explode anything inside, set all faces' material to nil; make a set of layers from 'visible' to 'invisible' and also a set of transparent materials ranging from 99% to 1% opacity, make copies of the group and edit their layers and materials to suit; now set up a series of scenes/pages with the same view, but with each having different layers on/off, so when you move through the scenes the group appears to fade away or reappear...

Hi folks.

You can also try using the Fog.

Create scenes and then increase the fog effect in each successive scene untill the object is barely visible or invisble if you want.

Animate that to see the effect. A short transition time and many scenes can give a good result.

Just ideas.

Fog is a great idea if all things are to fade...

Jim

It is a good idea, and will be put to use.

Something like the following is how it might fit into what I have already:


Animation.add('fog', start_value, end_value, duration (frames or seconds), easing_function)
Animation.add (...)
Animation.play
