18 | \brief |
---|
19 | Specialisation of OGRE's framework application to show the transparency, |
---|
20 | or scene blending features. |
---|
21 | \par |
---|
22 | Note that this is a little rudimentary - it's because whilst |
---|
23 | OGRE supports lots of blending options, the SceneManager has |
---|
24 | to ensure the rendering order is correct when object transparency |
---|
25 | is enabled. Right now this is not quite right in the default |
---|
26 | manager so this scene is kept deliberately simple. |
