#MakingMapsPretty I’m developing a #QGIS tool to generalize and smooth a DEM, then generate a shaded relief and matching contour lines, all adapted to the selected level of generalization. Azimuth, height, Z-factor, and contour interval are controlled with a single click.

Want your drawings to look more realistic? Watch this video! #MEEDEN #howtodraw #drawingtutorial #pencildrawing #coloredpencil If you want your artwork to look more realistic, stop thinking of objects as flat outlines. Instead, start seeing them as 3D forms. Every object has volume. Once you understand that volume, you'll know exactly how to shade, color, and add depth. One of the easiest ways to train your eye is by using contour lines. 1. Start with a simple shape, like a sphere. Draw the basic outline first, then add curved contour lines that wrap around the surface. Think of them like the lines on a globe they follow the form and instantly make it feel three-dimensional. 2. Now imagine where your light source is coming from, and lightly sketch in the shadows. Suddenly, the shape has volume. This works for almost any object. Try it with a cylinder, an oval, or a cube. The contour lines should always follow the direction of the surface, helping you understand how the object turns in space. 3. Now let's apply the same idea to a simple apple. Begin with the outer shape, then draw contour lines across the apple to understand its round form. Don't worry about making them perfect they're just a guide. Once you can visualize the volume, adding color becomes much easier because you'll know exactly which direction your pencil strokes should I follow. 4. The same principle applies to a banana. Instead of coloring with random strokes, let every stroke wrap around the curve of the fruit. Follow the contour lines as you build up your layers. This simple change makes the banana feel fuller, rounder, and much more realistic. So next time you draw, build the structure first, then let your contour lines guide every stroke. Give this technique a try on your next drawing, and you'll be surprised by how much more realistic it looks.
