![]() In 2017, researchers at Karlsruhe Institute of Technology (KIT) developed a sterelithography (SLA) method to 3D print glass, at high resolution, a few tens of micrometers, and possibly even 150-500 nanometers (just ten times the size of silica particles). ATTRACT is in turn funded by the EU Horizon 2020 program, and so far has provided grants to 170 projects focused in breakthrough innovation. You’ll just have to scale it larger once you start working on the actual installation.The OptoGlass3D project is funded with a one-year €100,000 grant from ATTRACT, a collaborative initiative bringing together the research, industry and investment communities in Europe to develop the next-generation of sensing and imaging solutions, by streamlining breakthrough innovation, and using new, open innovation models at scale. Even if you're planning on making a large sidewalk drawing, starting with these graphs can help you plan out your design.You may want to label the rows and columns with numbers and letters to help you keep track of each square.The number of lines you’ll use will depend on the size of your drawing, but for a simple sketch, a 5x5 grid is a good place to start. Don’t make the squares too small, or it will be hard to see the details of your drawing.The more dramatically you angle the lines, the larger the object will seem. The bottom of the graph (typically the part closest to the photo point) should be the widest, then it should become more narrow the further up the page it goes. Once you know where you want your photo point to be, use a ruler to draw a graph with angled lines so it looks like the graph is trailing into the distance. Draw a line graph with vanishing perspective lines.
