Image

) to add an image as a plot. You can add it to 3D and 2D plot groups as an image on the surfaces of the plot. You can also add Image (Plot Attribute) subnodes directly to a 2D or 3D plot group. Right-click the Image node to add Deformation, Material Appearance, Translation, Transparency (3D only), or Visual Effects (3D only) subnodes if desired.

	Go to Common Results Node Settings for links to information about these sections: Data, Selection, Title, Quality, and Inherit Style.

Click the button (

This section controls how the image is mapped to the 2D and 3D surfaces; you can choose an automatic or manual mapping as well as predefined planar, cylindrical, and spherical mappings for 3D surfaces and a rectangular mapping for 2D surface.

•

When the list is set to , an automatic planar projection algorithm is used to map the image to the surfaces. The setting always finds the best fitting plane and projects on it while choosing a suitable projection size. If the check box is selected (the default), then the image’s aspect ratio is preserved by the automatic mapping algorithm. If the image and the data have aspect ratios, then some padding must be added. The images are centered in the dimension where padding is needed.

•

When you select from the list, you get access to more detailed control over the mapping. Each point on the surface is mapped to a pixel in the image. This functionality can be used for more advanced mappings. The following example provides a mapping that embeds a world map that uses an equirectangular projection on a sphere of radius r centered at the origin (when using a relative coordinate interpretation):

•

When you select from the list, you can define a plane for the image to be mapped to. From the list, choose one of the following planes: , , , , , , (the default), or . For , the software chooses the plane type that best suits the selected surfaces.

Enter a under , which is the side length that the image will have, interpreted in the length unit of the geometry that the solution dataset refers to. The will be computed based on the image’s size. Also, provide the coordinates for an anchor point in the , , and fields under . For , specify a normal vector in the , , and fields under . The default is (0, 0, 1); that is, the positive z direction). Also specify a rotation angle, in degrees, if desired, in the field.

•

When you select from the list, you get a cylindrical mapping of the image. Specify the position of the cylinder (center of the bottom circle) in the , , and fields under , and from the list under , choose , , s (the default), , or . For , specify the axis direction in the , , and fields. For , specify the axis direction in the and fields as θ and φ angles in degrees. Under , specify a rotation angle, in degrees, if desired, in the field and an angle range, in degrees. for which you want to apply the mapping (default: 360 degrees). Under Height, choose one of the following options from the Mode list: (the default), , or . If you choose , enter a height and a displacement in the and fields, both in coordinates in the geometry’s coordinate system and its length unit. The displacement is the shift along the axis measured from the middle.

•

When you select from the list, you get a spherical mapping of the image. Specify the position of the sphere’s center in the , , and fields under , and from the list under , choose , , (the default), , or . For , specify the axis direction in the , , and fields. For , specify the axis direction in the and fields as θ and φ angles in degrees. Also specify a rotation angle, in degrees, if desired, in the field.

•

When you select from the list, you define a rectangle for the image to be mapped to. Enter a under , which is the side length that the image will have, interpreted in the length unit of the geometry that the solution dataset refers to. The will be computed based on the image’s size.

From the list under , choose (the default), , or to control the type of extrapolation to use. The effect of the option is that each coordinate is mapped to the closest valid value at an edge of the image. The list is not available when you have selected the or mapping from the list.
