# Controlling perspective (and how to use Rendering Pane)
After adding a new layer or selecting a layer from the list, **Rendering Pane** displays the meteorological data in the 3D-image and contains some options for controlling perspective.
You can control the display options in **Rendering Pane** as follows.
### Setting color map and limit range
* You can edit the color map and limit range of the current layer as follows:
1. Double-click the *Color Bar* or the *Limit Range*.
1. In the *Setup Colormap and Limit Range* dialog box, you can customize the options for the layer, and click *OK* button.
* In the *Colormap Range and Levels* panel, you can set options for the layer's colormap.
* In the *Limit Range to Display* panel, you can set the display range of the layer.
* In the *Contour Levels* panel, you can set options for creating isopleths (contour lines) to display Horizontal Plane/Vertical Cross-Section type layers.
* In the *Emphasis Level* panel, you can set the display options to highlight certain lines from the isopleth data to be displayed on the Horizontal Plane/Vertical Cross-Section layer.
Note that the options in the *Contour Levels* panel and the *Emphasis Level* panel are applied only if the selected layer is a scalar (Horizontal Plane/Vertical Cross-Section) layer.
* The alternative way to edit the options for the current layer is as follows:
1. In *Menu Category*, choose *Home* category.
1. In *Layer Setup* panel, you can
* click the upper part of the *Layer Option* button to see the *Setup Colormap and Limit Range* dialog box; or
* click the lower part of the Layer Option* button to select the detail setup options.
