Member Function Documentation

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

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().

void LineDrawingGLSLMode::after_drawing_outside_dl ( const Patch * patch ) [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 from RenderingMode.
Definition at line 893 of file line_drawing.C.
References glUseProgramObjectARB.

virtual GLStripCB* LineDrawingGLSLMode::get_new_strip_cb ( ) const [inline, 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.

Implements RenderingMode.

LineDrawingGLSLMode& LineDrawingGLSLMode::operator= ( const LineDrawingGLSLMode & rhs ) [private]

void LineDrawingGLSLMode::setup_for_drawing_inside_dl ( const Patch * patch ) [virtual]
