Detailed Description

The abstract interface for a rendering mode.

Rendering modes determine how a gTexture is rendered (for example, using just shaders, using shaders and textures, or using no shaders).

Concrete rendering modes should subclass this class and override one or more of the setup_for_drawing or after_drawing methods. Subclasses should also create their own subclass of RenderingModeStripCB to act as the GLStripCB for their gTexture. The get_new_strip_cb() method should be overriden to return a newly allocated one of these RenderingModeStripCB subclasses.

Note:

Each concrete rendering mode is responsible for managing all the OpenGL resources it needs for rendering. These resources will most likely be allocated in the rendering mode's constructor and deallocated in the destructor.

Member Function Documentation

virtual void RenderingMode::after_drawing_inside_dl (  const Patch *  patch  )  [inline, virtual]

Perform any operations that should happen after drawing is complete. This method will be called once inside a display list. Definition at line 67 of file rendering_mode.H. Referenced by RenderingModeSingleton< RenderingModeSelectionPolicy >::after_drawing_inside_dl().

virtual void RenderingMode::after_drawing_outside_dl (  const Patch *  patch  )  [inline, virtual]

Perform any operations that should happen after drawing is complete. This method will be called each time the style is drawn. Note: Code that uses values that vary from redraw to redraw should be put in this method so that the values are not captured once in a display list. Reimplemented in LineDrawingGLSLMode. Definition at line 63 of file rendering_mode.H. Referenced by RenderingModeSingleton< RenderingModeSelectionPolicy >::after_drawing_outside_dl().

virtual GLStripCB* RenderingMode::get_new_strip_cb (   )  const [pure virtual]

Get a newly allocated object of the GLStripCB class used by this mode. Note: The returned GLStripCB pointer should be deleted by the caller when it is done being used. Implemented in CurvatureARBvpARBfpMultiTextureMode, LineDrawingVprogFprogNoSSDMode, and LineDrawingGLSLMode. Referenced by RenderingModeSingleton< RenderingModeSelectionPolicy >::get_new_strip_cb().

virtual void RenderingMode::setup_for_drawing_inside_dl (  const Patch *  patch  )  [inline, virtual]

Setup the OpenGL state for rendering in this mode. This method will be called once inside a display list. Reimplemented in CurvatureARBvpARBfpMultiTextureMode, LineDrawingVprogFprogNoSSDMode, and LineDrawingGLSLMode. Definition at line 55 of file rendering_mode.H. Referenced by RenderingModeSingleton< RenderingModeSelectionPolicy >::setup_for_drawing_inside_dl().

virtual void RenderingMode::setup_for_drawing_outside_dl (  const Patch *  patch  )  [inline, virtual]

Setup the OpenGL state for rendering in this mode. This method will be called each time the style is drawn. Note: Code that uses values that vary from redraw to redraw should be put in this method so that the values are not captured once in a display list. Reimplemented in CurvatureARBvpARBfpMultiTextureMode, LineDrawingVprogFprogNoSSDMode, and LineDrawingGLSLMode. Definition at line 51 of file rendering_mode.H. Referenced by RenderingModeSingleton< RenderingModeSelectionPolicy >::setup_for_drawing_outside_dl().
