I need to create an image in a format that can be burned on wood with a heat-pen. I was wondering if anyone is familiar with some functionality (free preferably online or in a own software) which can convert an image into a dotted image, where each dot is proportional in size to its position in the depth of the image. So if the y-axis is inward and outward of the image, the a dot is smaller the more the respective countour of an object is distant from the viewer. The closer the respective contour or point of that image is to the view, the larger the dot becomes.
Here is an example of dotted images: https://www.google.com/search?q=dotted+images&client=firefox-b-lm&source=lnms&tbm=isch&sa=X&ved=2ahUKEwipqdyVwpX_AhWLU6QEHeIABFMQ_AUoAXoECAIQAw&biw=1467&bih=694&dpr=1.09
However, I would like to generate a dotted simplified version of the following image
Any ideas appreciated.
