![]() inflation readings and interest rate decisions later this week from the U.S. Treasury yields and the dollar were virtually unchanged ahead of key U.S. NEW YORK/LONDON, June 12 (Reuters) - Global stocks gained ground, hitting their highest level in more than a year on Monday, while U.S. Fed expected to skip rate hike this week.In the video below, the adaptive window is represented in red. Once points converge (stop moving beyond some threshold), they are removed from the adaptive window. These two steps are iteratively applied to an adaptive window of recent samples and rendered after each pass of the smoothing process. This spline has very nice properties in that it generates curves with smooth curvature and zero discontinuities. Given the filtered input points, Meander now uses those points as control point inputs to a uniform quadratic b-spline. This smoothing operation is very subtle such that artists don’t realize it’s happening - if they did notice, it would compromise the desired illusion of drawing on real paper or canvas. ![]() In order to generate a smooth curve representation, Meander uses a 2-step approach applied in an adaptive window of the most recent samples from the input device.įirst, the points input from the device are “faired” or smoothed. If an application simply connects these points with straight lines, the strokes will appear jagged and contain hard angles. Each device delivers sequential points at a particular frequency representing the path of the input. Meander accepts input from any standard input device, such as a mouse or tablet. For easy integration into a variety of applications, MeanderKit also has C and Python API layers, which allow for the integration into C, ObjC, Python and Swift applications. Meander and MeanderKit are both written in C++ for fast performance and leverage OpenGL for hardware-accelerated rendering. This technique was also used in the short-film Feast. This allowed us to create the effect of an animated painting on Paperman– with all the benefits of CG animation (smoothness, depth, stability) and combine it with the benefits of hand-drawn animation (emotional cues from lines, every frame drawn to camera). Given 3D animation and strokes drawn on top, those strokes are then “carried” along with the 3D animation but always drawn as two-dimensional strokes. Taking this concept a step further– on Paperman, the stroke geometry could be “attached” to an underlying 3D animated character. While the system cannot make artistic choices, it can however assist the artist in doing arduous tasks such as inbetweening subtle movements that require great precision. For example, Meander has inbetweening capabilities– given similar drawings on different frames, the system can interpolate the strokes and draw them as if the artist had drawn them. Once we could ensure that the drawing quality was as good or better than all other drawing tools, we could then focus on adding the new abilities that the geometric information would allow. ![]() To be compelling, Meander has to empower artists in ways not possible without a computer while not compromising the ease-of-use of paper. In the case of drawing, it’s difficult to improve upon pencil and paper. ![]() The primary goal of any artistic tool is to allow an artist to express their intent as quickly and easily as possible– unencumbered by complexity of interface. In short, Meander stores the geometry and characteristics of a stroke (its centerline, width, color, pen) but renders the curves similar to how a raster program does.
