This sketch creates a 3D model from a text, based on text structure. (A text consists of paragraphs, a paragraph of sentences, a sentence of words and a word of letters)
You can explore the structure using primitive picking.
Use standard peasycam controls to manipulate camera:
*Click & drag to rotate, scroll to zoom, arrow keys to pan
*Click nodes to highlight their structure & display the text element they represent (text > paragraph > sentence > word > letter)
*Press & hold enter to reset selection
