Blender demo loop

[ton]

One of the new python features is the possibility to make an automatic running loop, showing .blend files, play anims, render, do radio calculus, and so on.

You can grab what I quickly assembled for siggraph:
(with help from Ianwill
http://www.blender.org/bf/demos.zip (2.5 MB)

Just drag one of the .blend files on top of a 2.34 Blender executable (works with osx, windows, linux). Or start blender 2.34 and load a file.
You can exit looping by pressing ESC (sometimes twice).
In the current API, only the Play() call returns an event to denote ESC is pressed, so that's still a bit awkward.
(For useful demo looping having an ESC is crucial.)

Nevertheless, it's a very interesting method to explore two things;
- an automatic testing environment
- make a demo CD to hand out on tradeshows and send to stores

Especially the latter I like to do work on; it should be possible to make a demo cdrom that shows all kinds of Blender features in a loop, and which doesnt require any installation at all (e.g. runs from CDROM completely).

I would need more experienced python scripters for it however, so hopefully people like to pick this up and create their own 'demos'
The current python API allows to do *very* interesting things!

Uber cool Ton.

Good luck for Siggraph '04.

pretty cool!

Q - could it also be used for tutorials?



have fun there in the states, and try to get jos stam working for blender!

Yes, it could be used for interactive tutorials. It'd require some time for scripting it, but you can ie. enter/leave editmode for an object through the blender python api. Also, you can set what layers are visible, so you could make a progress chain in different layers and wait for specific user input to switch to the next, or add layers progressively.

... Also, you can set what layers are visible, .../jesterKing

How can we do this in the current API ? I mean : set a layer visible or not.

Thanks for posting this Ton! I have been hoping for something like this in Blender for a long time. I will find many uses for this feature in my work.

See the function ViewLayer from the Window module.

I just noticed that the python documentation on b.org needs still to be updated.

A sample of what you can do with the layers:

Thanks jesterking for posting the demo and links.

Thanks jesterking for posting the demo and links.

The best way to thank is learn and apply. Post some über-groovy stuff, make us happy

Point taken.

Eeek, that's something I've forgotten to do: Make new docs and upload them - well tell you where to get them so you can put them online

If I forget to create those, just mention it on irc this evening


With regards,
Michel

awesome stuff, nice feature.

Nice, Demoloop is back

So is it already possible to start the gameengine from the new python API? And to give back control to the demoloop....

Carsten.

another testiment to alleged crossplatform compatibility
