Themen

Lighting Overview
You can position light sources and adjust the characteristics of the objects that are reflecting the lights.
Reflectance Characteristics of Graphics Objects
You can specify the reflectance characteristics of patch and surface objects and thereby affect the way they look when lights are applied to the scene.
Add Transparency to Graphics Objects
The transparency of a graphics object determines the degree to which you can see through it. Add transparency to graphics objects to customize the look of your charts or reveal details about an object that are otherwise hidden.
Changing Transparency of Images, Patches or Surfaces
This example shows how to modify transparency of images, patches and surfaces.
Modify the Alphamap
Every figure has an associated alphamap, which is a vector of values ranging from 0 to 1. You can view or modify the alphamap.
