generative modeling for Rhino
How can I add an image or a text in the grasshopper canvas??
For importing an image (but single colored vector graphic): take a look at this topic:
If you want your image to be in color like original, you can simply drag it and release it onto the canvas, and an image sampler with an image in it will appear.
For text you can use the Rhino tool called Scribble (in Params->Special toolbar).
Or you can even double click on a yellow Panel and type in something, then click OK.
Thank you, :).
