|
|
*
|
|
* Fog vs texture: We apply the fog in the vertex color. An app could set up texturing settings which
|
|
* ignore the vertex color, thus effectively disabling our fog. However, in D3D this type of fog is
|
|
* a per-vertex fog too, so the apps shouldn't do that.
|
|
*
|
|
* Fog vs lighting: The app could in theory use D3DFOG_NONE table and D3DFOG_NONE vertex fog with
|
|
* untransformed vertices. That enables lighting and fog coords at the same time, and the lighting
|
|
* calculations could affect the already blended in fog color. There's nothing we can do against that,
