Title: An Exploration into Computer Graphics: L-Systems and a Non-Photorealistic Filter
Abstract: LSystems : • L-systems are a Photorealistic method to render trees and other fractal like designs. • To build the L-systems below, I used a 3D turtle, which follows the position and orientation of the fractal as the lines are drawn. • The basic commands in an L-system are: ‘F’ move forward, ‘-’ move left, ‘+’ move right, ‘[ ‘ branch forward, and ‘]’ branch backwards. Branching allows for trees to be drawn. For more complex L-systems more commands can be defined. NPR Filter: • NPR is a field in computer graphics that puts emphasis on artistic expression. • This filter was inspired by a SIGGRAPH paper on picking isoluminant colors and applying them to create images that look like Chuck Close’s artwork. • Up close, you will see a mess of dots or shapes, but as you move farther away from the poster, the image will become clearer. • The different filters depend on how the isoluminant colors are drawn into the image.
