Cast shadows layer in Eduard
This layer computes shadows cast by a source of illumination.
Adjust the horizontal Illumination direction with the round slider. The illumination angle is relative to the default top-left direction. Click on the small dot at the top-left of the round slider to use the default top-left direction of 0°.
The Altitude Angle is the elevation angle above the horizon of the light source. With an angle of 0°, the light source is at the horizon. With an angle of 90°, the light source is at the zenith, that is, vertically above the terrain.
Minimum Shadow Length removes small batches of cast shadows. The distance is in pixels.
Gaussian Blur smooths the outlines of the cast shadows.
Adjust the granularity with the Details slider.
Oversampling reduces the jaggedness of cast shadows when viewed at a close distance.
Hint: A cast shadows layer has a 50% opacity and a multiply blend mode. Adjust layer blending and opacity by clicking on the circular half-filled icon in the list of layers.
