- Digital art encompasses various forms created or presented using digital technologies (, , )
- Digital technologies include hardware (computers, tablets, displays) and software (image editors, 3D modeling tools, programming languages) used to create, manipulate, and display digital art
- Pixel is the smallest unit of a digital image arranged in a grid to form a complete image
- Color models are systems for representing and specifying colors in digital art
- (red, green, blue) is commonly used for digital displays
- (cyan, magenta, yellow, black) is used for printing
Raster vs vector graphics
- Raster graphics are images composed of a grid of pixels, each with a specific color value
- -dependent: quality degrades when scaled up
- Suitable for photographs and complex images with gradients and textures (, , , )
- are images defined by mathematical equations and geometric primitives (points, lines, curves, shapes)
- Resolution-independent: can be scaled without loss of quality
- Ideal for logos, illustrations, and designs with clean lines and shapes (, , , )
Resolution and color depth
- Resolution measures the number of pixels in an image, usually expressed as pixels per inch (PPI) or dots per inch (DPI)
- Higher resolution means more pixels and greater detail
- Affects image quality, file size, and printability
- (bit depth) is the number of bits used to represent the color of each pixel
- Higher color depth allows for a wider range of colors and smoother gradients
- Common color depths:
- 8-bit (256 colors)
- 16-bit (65,536 colors)
- 24-bit (16.7 million colors)
Generative Art and Algorithms
Algorithms in digital art creation
- is a set of instructions or rules that a computer follows to perform a task or solve a problem
- Used in digital art to create, manipulate, or analyze images, animations, and interactive experiences
- is created using algorithms and autonomous systems
- Artist defines the rules and parameters
- Computer generates the artwork based on those constraints
- Can produce unique, complex, and unpredictable results
- is the algorithmic creation of content (textures, 3D models, landscapes)
- Allows for the generation of large amounts of varied content with minimal manual input
- involves using programming languages and frameworks to create interactive and generative digital art
- Popular tools include , , , and
