3D drawing with your fingers

The 3D technology is developing new and amazing applications and tools every day. It is no longer a thing of the future, but a daily amazing discovery that we all make. Just like kids discover how much fun it is painting with your fingers, adults can now use a touchscreen in order to start 3D drawing, all by themselves. More than this, the 3D drawings can be used for 3D printing afterwards. In the past, finger painting for printing would involve scanning a 2D drawing from a piece of paper and rendering it in 3D – that is what 2D-Drawing-for-3D-Printing would be all about. The future brings is 3D-Drawing-for-3D-Printing, by using the new Draw In 3D application for touch screen mobile devices.

Apart from the 3D technology applications dedicated to engineers, architects and marketing specialists, the new developments are now targeting a more entertaining approach. It is all about fun, as the HP announcement states. The playful field of 3D-Drawing-for-3D-Printing is launching on a new and amazing adventure. Individual developers, such as Steffan Poulsen, a solo developer based in Aarhus, Denmark, are also taking a stand, presenting new 3D drawing applications. The developed product addresses beginners, schools and leisure consumers alike, in order to provide easy to use tools that can turn the touch of your fingers into a 3D schetch ready to print out in a 3D model.

Drawing directly in tangible 3D space is definitely something that kids will grow up accustomed to, since the tools that are being developed nowadays are as simple to use as a regular pen. The new Draw In 3D application for the Apple iPad, makes it easy and fun to draw in three dimensions. Using just common gestures creates a drawing. Panning around the space, pinching-to-zoom, and choosing colours can be done by selecting items from a pallette icon.

3D drawing made easy

The principle is easy to understand, as it uses drawing Cartesian freeform lines and using camera rotate with polar coordinates in Euclidean space. ”I decided to try to disable the slowdown of the camera momentum, when rotating around the drawing. The result, of course, was that the camera kept spinning. Then I tried to draw while spinning – magic! It felt like a mix between drawing on paper and doing clay pottery. That was the moment ‘Draw In 3D’ was really born. That was two years ago, and today, I am proud to present the final product”, Steffan Poulsen explains.

The kids will surely appreciate it. Adults alike might find it intriguing enough to try. The result is It is colourful, friendly and fun. The future of 3D drawing is full of color.
