Yes, you can display your points in 3D space in the 3D View. In order for the points to be displayed, the following conditions must be true:
- The points must be in a Post, Classed Post, Base, or Base from Data map layer
- At least one point in the layer must have third data column or attribute (as well as the X and Y position), which must be numeric. This will be used as the Z coordinate. Other points in the layer that lack a Z coordinate will not be displayed in the 3D View as true 3D points, although they may be displayed as texture overlays on a surface.
To view point data in true 3D space in the 3D View:
- Create a Post map, Classed Post map, Base map , or Base from Data map. Your Map frame may also contain other types of map layers.
- Create the 3D View by either right clicking over the map or layer and clicking the 3D View command, or by selecting the map and clicking Map Tools | View | 3D View.
- The Contents window shows Environment and Vector Data:
- Select the Post object from the Contents window under Vector Data. The properties for this layer are displayed in the Properties window.
- Set the Z coordinates field:
- If your data file contains columns named Z, ZLEVEL, ELEVATION, or DEPTH, then the Z coordinates field will be automatically populated, and your point data will be displayed.
- If the conditions above or not fulfilled, then you will need to manually select a data column in the Z coordinates field. The points will now appear in the 3D View.
- The symbol can either be set as Same as Plot or a fixed 3D Symbol. If Same as plot is chosen, the symbol will be the same as those chosen on the Plot View (2D View). Changing the symbol in the Plot View will also change the symbol in the 3D View.
- The symbol size can be either Same as plot, Fixed, or Proportional. If Proportional is selected, a Size data column must be selected that defines the scale of proportional sizing.
- The symbol color method can be set to Same as Plot, Fixed, or By colormap. If By colormap is selected, a Color data column must be chosen that defines the stretch of the colormap.
The Environment and Surface parameters can also be controlled in the 3D View. You can watch a brief overview of the 3D View features here: Surfer 3D View Training Video
