![]() ![]() The Spacing Adjustment control allows the spacing to be modified to produce a more pleasing result, as shown in the right (blue) example. However, if it's interpreted as a tilted circle, the circles become crowded together as they recede into the distance. When interpreted as an ellipse perpendicular to the viewing direction, the spacing makes sense. Most of the controls are self-explanatory, but the Spacing Adjustment may require some explanation.Ĭonsider the left (red) ellipse in this example: The number of subsamples is this value squared. ![]() Enables and disables antialiasing.Īntialias Quality: The number of subsamples per pixel. If disabled, only the subsequent copies will be kept.Īntialias: Antialiasing preference. Keep Original Object: Option to keep the original object. Trail Transparency Adjustment: The amount to increase the trail transparency. A value of 1 produces exponential fades - the opacity of the copies decreases by a constant ratio. A value of 0 produces linear fades - the opacity of the copies decreases by a constant amount. The opacity (alpha) of each pixel's final copy is approximately equal to the pixel's original opacity multiplied by one minus this value.įade Profile (0 for Linear 1 for Exponential): The type of fade. Generally, 0 works well for objects that represent two-dimensional objects which are parallel to the canvas, while 1 works well for objects that represent three-dimensional objects, provided the vanishing point is appropriate.įade Amount: The amount by which object copies decrease in opacity with depth. This can be useful to produce an appearance of even spacing between the copies of objects that represent three-dimensional objects. Increasing this value leaves the position of the first copy and the last copy unchanged, while shifting the other copies toward the first copy, with the nearer copies shifted more. ![]() Spacing Adjustment: The amount to adjust the spacing between object copies. When Perspective is 0, object copies do not decrease in size. Perspective: The rate at which object copies decrease in size with depth. Decreasing Perspective moves the vanishing point outward along the line through the canvas center and the specified location. When Perspective is set to its default value of 1, this is the actual vanishing point. Vanishing Point: The location of the vanishing point. (Due to perspective, the copies become closer together in screen-space as they recede into the distance.) Repetitions: The number of times each object is repeated at increasing depths, including the original object.ĭistance: The apparent distance between the object copies. (An "object " is a region of non-transparent pixels surrounded by transparency.) Closely spaced copies can also be used to add the appearance of thickness to objects. Vanishing Trails produces multiple copies of objects which appear to recede into the distance. ![]()
