I have set up a Google Spreadsheet that receives real-time data from a vibration sensor, with values ranging from 0 to 100. I managed to retrieve this data using a WEB DAT in TouchDesigner.
I’m looking to create an animation where an image of a circle appears and then slowly fades out, depending on the intensity of the vibration. How can I achieve this? Specifically, I’d like to know how to use a Math CHOP to process the data and link it to a Transform TOP for the animation.
Additionally, I would like to know how to set up the WEB DAT to request and update the data at regular intervals. Any guidance would be greatly appreciated!
under the assumption that the data is now available in TouchDesigner as a Table DAT, you can convert this to a CHOP using the DAT To CHOP. Now you should have a channel containing all the values from your original spreadsheet which, using a Lookup CHOP can be played back over time.
This value can be adjusted using a Math CHOP and finally exported or referenced in the Transform TOPs parameter of your choice (scale perhaps).
The Web DAT has a Request parameter which can be pulsed using for example an LFO CHOP.
