![]() ![]() If you've found this educational demo helpful, please consider supporting us on Ko-fi. ![]() The square root of x (for positive x only)Ĭontour lines can be a bit difficult to understand, so if you are having trouble, you may find the 3D surface plotter useful to help visualise the actual shape of the 3D surface. It is amazing how this AI model can generalize the transformation to not just face. The inverse of the three trigonometric functions listed above ArtLine transforms any image into sketch or something similar to line art. ![]() The table below lists which functions can be entered in the expression box. To update the function that the graph is showing, enter the new function in the input box, and click "update". You can see how the contour lines equate to the colors in the key just below the graph. While other APPS are displaying contours from topo maps, we generate contours with configurable interval, using sophisticated GRID and TIN interpolation approaches which are also configurable and. This is premium modul & need internet connection. By default they are set to (-100,100) and 21 respectively, so this means that the displayed contour levels will start at -100 and go up to and including +100 in intervals of 20. Vector programs are drawing programs so converting a photograph into vector format means making a drawing of the photo. Module to generate contours based on number of contour lines, desired elevation or contour interval. You can change which values the contour lines should display by tweaking the "Range of contour levels" and "Number of contour levels" sliders. There's nothing special about which contour lines are displayed, it's just a matter of choice. This is because you are looking at part of the graph that is very steep and a small change in x or y will have a big effect on the value of z. You might also notice that when you have many contour lines close together, if you go slightly off the line, the z value quickly deviates from the line's z value. See how the z value always stays the same. Try picking another contour line and follow it with your mouse.

So, that explains why we see a contour line along the line x = y. You should see in the sidebar that the (x,y,z) indicator displays (2,2,0). You can use this tool to create contour lines for any function you input Maths Geometry Contour Contour Lines Key: If you've ever looked at a map, particularly of a hilly or mountainous region, you may have noticed groups of lines like this: These are known as contour lines, and every point on the line is at the same height. So if x = 2, and y = 2, z will equal 4 - 4 = 0. Each point also has a z value which is calculated by plugging the x and y values in to the expression shown in the box. In the demo above, every point in the graph has an x and y value. Download PNG SVG Download contours as vector graphics. Contour lines aren't just limited to giving us info about mountains though, they can help us visualise a surface described by a mathematical function. These are known as contour lines, and every point on the line is at the same height. If you've ever looked at a map, particularly of a hilly or mountainous region, you may have noticed groups of lines like this: ![]()
