Synfig, a free 2D vector animation software can create 2D animation for free and designed to be capable of producing feature-film quality animation. Synfig is actually originated from custom animation platform called as “Voria Animation Studios”, but when the voria studio animation closed down. The primary developer Robert Quattlebaum registers the free 2D vector animation software under open source GNU GPL in early 2006. Since then Synfig is under active development; the latest version released was Synfig
This free 2D vector animation software is capable of simulating soft shading using curved gradients within an area so that the animator doesn’t have to draw shading into every single frame. There is also a wide variety of other real-time effects that can be applied to layers or groups of layers like radial blurs, color tweaks that all are resolution-independent. Other 2D animation features include the ability to control and animate the width of lines at their individual control points, and the ability to link any related data from one object to another. Synfig also works with High Dynamic Range Imaging.
Overall, Synfig major features:
Most elements are vector-based, and all layers are parametrically generated, hence even when changing the target resolution of a project, the only pixelation will occur in imported raster images, not the built-in components.
Temporal resolution independence
Animation-key frames are automatically interpolated by the computer, resulting in smooth motion
High Dynamic-Range Imaging (HDRI)
By using floating-point math in the image calculations, HDRI processing allows canvases to internally understand a far greater range of pixel luminance, resulting in better lighting effects, and improved colour composition.
The draw tool already reads the pressure sensitivity channel off your favourite tablets, for natural line weighting, and more to come!
While it may not be obvious in this early state, Synfig (and its proprietary predecessors) has been designed from the ground up with animation workflow in mind.
Unlike purely SVG-based vector software, and most consumer-level animation programs, Synfig has full support for gradient paths – gradients that follow along a drawn shape. This allows artists to easily add soft shading to animation without the trouble of painting it onto every frame.
Synfig supports a multitude of layers of various types; geometric, gradients, filters, distortions, transformations, fractal and a few others.
However, You will also need to download Synfig Core, GTK+ Runtime Environment and Gtkmm installers. Install all three before installing Synfig Studio. Beside that, there are huge Synfig 2D animation resource of documentation, tutorials and an active community to help you learn out Synfig animation studio.
So, it would be nice to see some more shape tools in future versions like Synfig free 2D animation software. Meanwhile, this 2D vector animation support Windows, Linux and Mac.
