Shading

To access this command...

Open the context menu of the 3-D object, choose 3-D Effects - Shading tab.

## Shading

Specify the type of shading to apply to the selected 3-D object.

### Mode

Select the shading method that you want to use. Flat shading assigns a single colour to a single polygon on the surface of the object. Gouraud shading blends colours across the polygons. Phong shading averages the colour of each pixel based on the pixels that surround it, and requires the most processing power.

## Shadow

Adds or removes a shadow from the selected 3-D object.
