![]() You will need the VG.net build, or later, to view in the designer. To see the details of the shadows, and to examine the Picture for yourself, download the raindrop sample code. Let me introduce myself - I'm Drippy, the (un)official USGS Water Science School mascot. Water Science School HOME Water Basics topics Are Raindrops Shaped Like Teardrops Sources/Usage: Public Domain. Later I changed from an ellipse to a copy of the Spline shape. Science We all know that raindrops are shaped like teardrops, right Actually, that is not true. TwoColorBell must be used as a GradientType to get nice shadows. The shadow for each raindrop in the original picture is an ellipse, with a PathGradientFill, the center a translucent black color, and the edge completely transparent. This gives a tighter fit to the gradient. I made the bounds smaller than the Shape because the Shape is nearly diagonal. This pushes the most intense white to the upper-left, in the direction of Angle StartOpacity: 0 (completely transparent). ![]() The bell curve is great for rounded surfaces using a linear gradient. In the past, the nonspherical raindrops model had been investigated by several experts 15 16 17. The Fill property on the shine has these settings: In the calculations, information on the raindrop shape is necessary. The Spline was converted to a Path, and the control points were moved to make it look like the bent reflection of a rectangular light source: The shine on the upper left corner of each drop was created by first drawing a Spline. The Gamma Correction combo box was added in the build. If you do not see the combo box, download a new version of VG.net. Since GammaCorrection defaults to true, you must set it to false here. However, we did find a slightly expensive way to simulate this with two GradientTypes: TwoColorBell and TwoColorTriangular. You may remember we complained about the lack of gamma correction in the. Gamma correction is necessary when trying to simulate rounded surfaces. To get a "glow" or interior lighting effect, gamma correction must be set to false. ![]() I could have gotten the same effect by reducing the luminosity and saturation of the StartColor. I decided to make the gradient bounds a bit bigger than the Spline, to reduce the intensity of the StartColor. You can also drag the green adornement in the sample box with the mouse, until it looks good.
