====== Colour and appearance settings for implicit surfaces ======

CGRAPH displays implicitly defined surfaces as a point cloud formed from individual small cubes.

In addition to the **//colour//**, the **//size of the cubes//** can also be specified. However, this size is relative – the actual display depends on the position of a cube in 3D space. Cubes that are closer to the front are displayed larger than those in the background. 

Displaying the cube edges in a different colour facilitates three-dimensional perception. The edge display can be **//disabled//**, which speeds up the drawing process. The **//edge colour//** can also be freely selected. In addition, you can specify whether CGRAPH should **//only draw the edges when scaling up//**. This prevents the edge colour from being visible instead of the fill colour when scaling down.

Furthermore, the graphic as a whole can be drawn translucent by moving the **//transparency//** slider to the left. The default value for transparency when creating the graphic can be set in the [[3D graphics|settings]].

The example shows the approximate appearance that can be expected later in the graphic representation. The selected size of the cubes is marked in red in the example window.
