| === <tt>vtkProp::RenderTranslucentGeometry()</tt> is gone ===
| |
|
| |
| <tt>vtkProp::RenderTranslucentGeometry()</tt> is gone and has been broken down into 3 methods:
| |
| * <tt>HasTranslucentPolygonalGeometry()</tt>
| |
| * <tt>RenderTranslucentPolygonalGeometry()</tt>
| |
| * <tt>RenderVolumetricGeometry()</tt>
| |
|
| |
| Here is what to change in a vtkProp subclass:
| |
| * If <tt>RenderTranslucentGeometry()</tt> was used to render translucent polygonal geometry only, override <tt>HasTranslucentPolygonalGeometry()</tt> and <tt>RenderTranslucentPolygonalGeometry()</tt>. <b>Just renaming <tt>RenderTranslucentGeometry()</tt> to <tt>RenderTranslucentPolygonalGeometry()</tt> is not enough!</b>
| |
| * If <tt>RenderTranslucentGeometry()</tt> was used to render translucent volumetric geometry only, override <tt>RenderVolumetricGeometry()</tt>.
| |
| * If <tt>RenderTranslucentGeometry()</tt> was used to render translucent polygonal geometry and translucent volumetric geometry, override all 3 methods.
| |
|
| |
| The reason of this change is that <tt>HasTranslucentPolygonalGeometry()</tt> is used to decide if an expensive initialization of the new rendering algorithm of translucent polygonal geometry (depth peeling) is necessary. <tt>RenderTranslucentPolygonalGeometry()</tt> is called multiple times during the rendering of the translucent polygonal geometry of the scene. <tt>RenderVolumetricGeometry()</tt> is called in an additional pass, after depth peeling. For this reason, <b><tt>RenderTranslucentGeometry()</tt> cannot just be marked as deprecated but had to be removed from the API</b>.
