I need multiple text book illustrations made. They are technical as they are representing the orbital movement of the Moon, so a sense of geometry and perspective are important- in the attached image, the dotted line is the earth's orbit around the Sun, and the wavy line represents the Moon's slight upward and downward orbit as it circles the earth (from a side view). 14.7655 days correlates to degrees of the circle of the dotted line. Other images are similar. I made a project page to show the style I am looking for: http://shrifreedom.org/project-page/ Please give a link to similar portfolio work when replying for this job. I prefer to pay per image for the right artist.

We have developed a method for identifying polygon objects and recoloring their surface while preserving lighting conditions. This is a two part algorithm. Part one requires no user input, runs a custom line detection method, and finds all line intersections. Part 2a has a single coordinate as user input, extracts a color from that coordinate and finds a polygon around that coordinate using both the custom line detection from part one and color segmentation. 2b takes a user input color, maps the image to a different colorspace and changes the polygon around the user input to the target color to preserve shaging of the original image. Please note that the lightness of the input color is considered an important part of that color and cannot be separated from the input. We have a process in this algorithm which sometimes does not appear end and thus causes a drain on memory (perhaps a memory leak, not certain). As our application scales, this causes the server to run out of...
