Creating a 3D surface map without colors may be useful when draping an image base map over a 3D surface and you want to see the image in 3D with the 3D shading, but not with additional colors. To do this:
- Create the 3D surface map by going to Home | New Map | 3D Maps | Surface, selecting your grid file and clicking Open.
- Add any other map layers you choose by going to Home | Add to Map | Layer.
- Select the 3D Surface layer in the Contents window.
- In the Properties window, click the Overlays tab.
- Make sure the Color Modulation is set to Blend overlay and surface colors. Choosing Use overlay color only would work just fine to see only the overlay colors, but it would not have the 3D shading.
- Click the General tab
- Under Material Color, click the (...) button to the right of Upper.
- In the Colormap dialog, create an all white spectrum. To do this, select the GrayScale preset (at the top of the list), select the left color node on the color spectrum, and choose the White color from the Color drop down list.
- Once you have an all white spectrum, click OK.
- When I overlay an image on a surface in Surfer, it is too dark. How do I correct this?
- How can I overlay a 3D surface map with another map in Surfer, and see only the colors of the other map but with the shading of the surface map?
