A good alternative is MSPhysics. You can program camera and targets on paths at any speed or control them directly with sliders. The entire model to be driven through is set as to be ignored in order not to be subject to gravity and to fall down.... The animation can be saved and output as a SketchUp, Indigo, Twilight or Kerkythea movie. A scene animation is also possible.

Here is a short animation how the MSPhysics simulation of the flexible parts of the object (orca) is constructed in context. The code behind it is still a bit rudimentary and incompetent - but I'm still learning...

Hi HornOxx, your hammers would be a good example for an animation of the march with animator (Fredo6). The threatening effect comes across quite well in your renderings. At that time I recorded the concert of Pink Floyd in Berlin from the TV to a videotape.
Those were the days...

Models, textures, light, rendering, presentation - perfect!
I would like to touch the loose parts and put them together....

Thank you for your incredible efforts to develop plug-ins for building construction solutions. Even the renderings are getting better and better. I'm thinking about whether the techniques are also suitable for the requirements of building constructions in Germany... Keep up the good work!

I'm getting closer to the point.... In a day or two, I finally have my flexible caudal fin...

@HornOxx:
Don't try MSPhysics as it can be addictive.... Using gravity is the beginning of the end... Devil's work! You will neglect your job and your family, ultimately become lonely, impoverished and physically stunted. And yet you can't stop and you will always want to achieve more... And you will get it...
@Box:
Thank you for the playful application and convincing demonstration of some powerful plugins for creating a seemingly simple heap of stones! The hard part, which is now easy to do...

In my case, it is caused when Indigo RT sets a different aspect ratio for rendering in the active scene (for example, for a resolution of 1920x1080 or multiples of that) and when I apply these settings to the scene.
In the viewport, the different aspect ratio is typically represented by vertical or horizontal gray bars.
SketchUp 2017 (Make) does not cope with these settings of the render program during normal image export from the same scene and produces grey areas of different widths depending on the image resolution. Up to version SketchUp 2016 (Pro) this was no problem for me.
I use version 2016 Pro for work and 2017 Make for hobby (Animation, because MSPhysics only runs with 64-bit SketchUp).
Indigo RT (plugin "Skindigo") has in the menu "Skindigo Render Settings" a "Reset Camera" button, which also fixes this problem.
"Advanced Camera Tools" are, I think, a pro feature.

The complex looks good in terms of use, but is not very inspiring from an architectural point of view.
Involving an architect is not a bad approach. In such a big studio can blow a little more modern wind of design.

It's a problem of SketchUp 2017. Please look into this post:

Hi Anton,
Do you see a possibility that "non-collidable" set objects will be ignored by the Buoyancy Plane?

@Patrick: Twilight has an "Animation Editor" under "Twilight Render V2" in the extensions pull-down menu. There you can select quality, resolution, MSP Replay output etc. It could be helpful to test which scenes you include ore exclude into an animation in scene settings.

@rick149: great detailed model! Can't wait to see it in action.

You're one of the most extreme perfectionists I've ever seen.
A really excellent degree migration between photo- and non photorealistic representation. The steaming cup touches the i-dot on the whole thing...
I have a holiday feeling.

Here is an animation of the sailboat on a simulated water surface in a simple SketchUp style.
A simpler solution for displaying the phases of the sail during the MSPhysics simulation is the visibility control.
All phases of the sail are grouped and are switched visible ore invisible with a scripted random function. This eliminates the need for transformations and saves data volumes in MSP Replay.

Looks like your "Sketchy Shadow Experiments" were successful.
Otherwise a clean and clear presentation!

A very professional architectural approach to the existing building. A perfect visualization. But who needs the antennas at the chimney today?

I couldn't resist... Here is another example using the same technique as above.
For the intermediate phases of the sail I used the ingenious plugin "Soap Skin & Bubble".
The ship sailed from the 3D warehouse to me...

Again a very nice illustration! The virtual representation makes me want to play the game "brett"-hard and real again.

Thank you, men!
@Duane Kemp: Yes, modelling the intermediate forms of the joint is quite complex, since the oscillation runs sinusoidal and the angles to the respective end positions become smaller.
The automatic generation of the intermediate shapes of the joint depending on the oscillations (frequency, angle, power of the bend, reduction ratio, external influences (impacts) etc. would be ingenious. I'm a long way from that.
@Pixero: Thanks for the link to the Ruby examples! They are from the book "Automatic SketchUp - Creating 3-D Models in Ruby" by Matthew Scarpino, 2010. I have the PDF but not the Ruby files. So now I must not transform them myself.

Hello Anton, here an other little question:
When I let run "Replay" with active hidden geometry all emitted objects remain in there last position still after there lifetime. Is this normal? Could that explain why Twilight takes longer and longer to render the images during the simulation?
