摘要: Most of the applications in real world today are more toward non-photorealistic rather than photorealistic. Slihouette Rendering Algorithms is one technique that important creating image. It has been successful used various such as game engine, communicating shape, cartoon rendering and 3D terrain visualization. This paper explores how silhouette algorithms could be created using a data have extracted from Kedah topography map. Contour map convert raster to vector (vectorisation) order create grid Digital Elevation Model (DEM) data. The vectorisation software for producing these then into format suitable existing software. results produced compatible images Sik District, closer human drawn illustration look like an artistic style.
