Presentation in processing? Is my idea doable?

Hi,

Me and a co-worker are about to make a presentation of a project that’s almost completed. Its a change in layout in production flow in a factory.

Since we cant have a “grand opening” cause of the pandemic we are doing a demonstration on Wats done and I had an idea of making this presentation a bit more interactive than just a video och a report.

I am looking in to the possibility to make the presentation in WordPress but I also want to check with you programming gurus if this maybe possible in Processing?

I have a drawn image in this link on my vision on the flow of the presentation: https://imgbb.com/2yJsJ5t

I’m thinking like this
When I open the processing file I see a map of the factory from above. The map have some points marked out where I am able to click with the mouse.
If I click with the mouse on one of these point a “zoom in” animation starts so I feel like im traveling down to the building.
Here, I want a transition there the image fades out to all white and the page with the specific info based on where I clicked comes fading in from all white.

Also… I need video to play on the info pages…

I have no idea if this is doable in Processing and if it is, its above my skill level in programming so I would really appreciate some code examples to get me started.

My plan is to release the presentation 1st of april. We are documenting the videos and images for the presentation next week.

It would be awesome if we could use processing as a tool for this. Way cooler that sending a web page around :wink:

Hi! I did give some talks with slides made with Processing before

However it’s not “easy” in a sense that basically you need to build your own framework by yourself. If your goal is to include Processing sketches in your slides, presentation with Processing would be a great idea, but the interactive slides you proposed may need extensive development.

p5.js can be more powerful for transition effects because you can make use of HTML/CSS animations. But you still need to code a lot. Maybe looking into existing platforms like prezi would be more helpful as the first step.

Hi,

As @micuat said, this is exactly that :

Processing gives you all the building blocks if you want to code your own animation and transition framework in order to display text, videos, images…

It’s doable but it’s going to take time.

On the other side, you have the full power of the web technologies in order to display interactive slides and perform complex animations. You might want to look at https://revealjs.com/ which is a HTML presentation framework where you can integrate JavaScript and p5js for example!

Interesting

Maybe even MS PowerPoint can do this. Depends how you want to deploy the presentation (web or usb-stick or server or …)

When you try to do this in processing, a lot of ideas will come up (you haven’t thought of before) so you have to alter the framework and the data which would be VERY hard.

For example, have a Back button, additional movies and images on a page, start and stop button for the movie etc.

Also, 1st of April is very close…

That’s awesome!. But when you say VERY hard I guess I wont try to make my presentation in processing this time…

However!. This sketch is saved and it really showed me a new side of processing (as processing and programming seem to have a lot of sides) so I will take some time and really jump down this rabbit hole.

Thank you!

It allows you to do exactly what you described really simply!

You should take at look at Soby by Jeremy Laviole.
