/** Example 022 Material Viewer
|
|
|
|
This example can be used to play around with material settings and watch the results.
|
|
Only the default non-shader materials are used in here.
|
|
|
|
You have a node with a mesh, one dynamic light and global ambient light to play around with.
|
|
You can move the light with cursor-keys and +/-.
|
|
You can move the camera while left-mouse button is clicked.
