These properties control surface object visualizations. For each property, the type of control and the values that can be assigned are listed. For a description of how a particular control is used, refer to Property Controls.

Table D-44: Surface Properties

Table D-44: Surface Properties
Property | Control Type: Values
--- | ---
Color | Color: Color of the surface visualization. Click to choose from the default color palette, or specify RGB values. Default = `[255,184,0]` (gold)
Use color on bottom | Boolean: Display a color for the bottom of the surface. Choose True or False. Default = False
Image palette | User Defined: By selecting Edit Color Table Edit`` access the color table to manipulate surface color values.
Bottom color | Color: Color to be used for the bottom of the surface. Click to choose from the default color palette, or specify RGB values. Default = `[255,255,255]` (white)
Minimum value | Number: Minimum Z-Axis value of the surface plot. Edit the number to change the value.
Maximum value | Number: Maximum Z-Axis value of the surface plot. Edit the number to change the value.
Surface style | String List: Style used for rendering the surface. Select a style from the list. Choose from these values: Points: Data points in the surface are rendered as points. Wire mesh: Data points in the surface are connected with lines, forming a mesh. Filled: Data points in the surface are connected with filled quadrangles or triangles, forming a solid surface. Ruled XZ: Data points in the surface are connected with horizontal (Z-direction) lines, forming a grid. Ruled YZ: Data points in the surface are connected with vertical (Y-direction) lines, forming a grid. Lego: Stacked histogram-style plot in which each data value is rendered as an outline box covering the XY extent of the cell and with a height proportional to the Z value. Lego filled: Same as Lego, but the boxes are filled. Default = Filled
Fill shading | String List: Method used for shading the surface polygons. Select a shading method from the list. Choose from these values: Flat: Shades polygons with a uniform fill. Gouraud: Interpolates intensities from each vertex along each edge. Then, when the polygons are converted, interpolates the shading along each scan line from the edge intensities. Results in a more natural appearance. Default = Flat
Draw method | String List: Method used for drawing the surface. Select a method from the list. Choose from these values: Quads: Draw a surface composed of quadrangles. Triangles: Draw a surface composed of triangles. Default = Quads
Line style | Line Style: Style of lines used for constructing the surface. Select a style from the list. Default = (solid line)
Line thickness | Line Thickness: Thickness of lines used for constructing the surface. Select a thickness from the list. Default = `1`
Remove hidden lines | Boolean: Hide lines that show through the surface mesh or grid. Choose True or False. Default = False
Show skirt | Boolean: Display the edges of the surface as a filled skirt? Choose True or False. Default = False
Skirt bottom height | Number: Set bottom of displayed skirt to this height. Edit the number to change the value. Default = `0`
Texture interpolation | String List: Method used for interpolating selected texture map. Select a method from the list. Choose from these values: Nearest Neighbor: Assign the value of the nearest pixel to the pixel in the output image. Fastest method, but may cause jagged edges. Bilinear: Create a weighted average based on the nearness and brightness of the closest four pixels, and assign that value to the pixel in the output image. Default = Nearest Neighbor
Texture hires | String List: Method used for tiling the selected high-resolution texture map. Select a tiling method from the list. Choose from these values: No tiling: Do not use tiling LOD tiling: Use level of detail tiling Tiling: Use tiling Default = No tiling
Skip zero opacity | Boolean: Skip zero opacity for surface? Choose True or False. Default = True
Vertex Color Scale | User Defined: Select vertex color scale bottom/top.
Texture Map Scale | User Defined: Select texture map scale bottom/top.
