The Terminology of Digital Painting: Vector and Raster
Now that you have the digital illustration and digital painting software packages installed, it’s time to get into underlying concepts that span digital illustration and digital painting. Digital imaging software, such as GIMP, Photoshop, and PaintShop Pro are based on "raster" or pixel-based technologies. I wrote a book called Digital Image Compositing Fundamentals (Apress, 2015) if you want to dive into raster imaging in detail. There is also a "vector" or math-based technology that is used in digital illustration and 3D software packages such as Inkscape or Blender. I wrote a Digital Illustration Fundamentals (Apress, 2015) book, covering this area, if you want to dive into vector illustration in further detail as well.
