![]() In combination with line binding, users can animate their artworks with great ease. Take a look at this video if you are interested in the problem of colorize mask. But it seems not fast enough for production and hard to edit the content on canvas since it's based on pixelmap. You may be interested in statistics on some existing artworks, the number of polylines and points are critical to the performance of 2D arrangements.Ī similar feature offered by Krita is called " colorize mask". Third, send face data to GPU for rendering a colored polygon.Ĭompared to flood fill on high-resolution pixelmap, it can be 100~1000 times faster and the final artwork can be freely modified. Second, query with labeling curves' and fetch desired face data (faces are polygons generated from artworks). First, artists paint on canvas and meanwhile arrange the polyline data. In Ciallo, the color filling is separated into three steps. Color filling in 2D artworks is exactly a point-location problem. In computational geometry, the point-location problem is well-researched and widely used in GIS and motion planning. For example, on the upper part of the picture, blue strokes inside the character indicate fill in shadows, red strokes indicate highlights, green or yellow indicate contours need to be filled in combination with other strokes.Ĭiallo will utilize these labeling strokes for coloring. In animation industry, artists use labeling strokes to indicate how to fill colors. It's an anime about anime making.Īrtists cannot bucket fill in a vector graphics software like Adobe Illustrator or Inkscape. Curve binding for stroke editing and animatingįig.Help me out by staring on this project and follow up the evolution of 2D computer graphics. Artists would love to paint/animate their artworks and researchers could easily develop and test their 2D geometry/rendering algorithm in a real production environment. But I wish it could shine as free open-source software. Ciallo fixes some fatal rendering drawbacks in blender grease pencil and tries to provide more innovative tools.įor now, Ciallo is more of a personal research project. Here are some successful artworks drawn with the polyline method (in blender): GPencil open project. It's a wonderful toolset based on polylines in 3D space inside Blender. They are rendered with GPU and edited based on computational geometry algorithms.Ĭiallo is greatly inspired by Blender Grease Pencil. ![]() ![]() The name "Ciallo" is the combination of the Italian "Ciao" and English "Hello", and comes from the video game Sabbat of the Witch developed by Yuzusoft.ĭifferent from traditional pixel image or bezier curve based painting software, polylines/polygons are the first citizens in Ciallo. ![]() IntroductionĬiallo aims for improving 2D artists' work efficiency with modern GPU and computational geometry.
