What is path rendering?

3D Rendering vs. Path RenderingCharacteristic GPU 3D rendering Path renderingDimensionality Projective 3D 2D, typically affinePixel mapping Resolution independent Resolution independentOcclusion Depth buffering Painter’s algorithmRendering primitives Points, lines, triangles PathsPrimitive constituents Vertices Control pointsConstituents per primitive 1, 2, or 3 respectively UnboundedTopology of filled primitives Always convex Can be concave, self-intersecting, and have holesDegree of primitives 1 st order (linear) Up to 3 rd order (cubic)Rendering modes Filled, wire-frame Filling, strokingLine properties Width, stipple pattern Width, dash pattern, capping, join styleColor processing Programmable shading Painting + filter effectsText rendering No direct support (2 nd class support) Omni-present (1 st class support)Raster operations Blending Brushes, blend modes, compositingColor model RGB or sRGB RGB, sRGB, CYMK, or grayscaleClipping operations Clip planes, scissoring, stenciling Clipping to an arbitrary clip pathCoverage determination Per-color sample Sub-color sample
