| void OpenTissue::gl::CrossSections< grid_type >::get_bitmaps | ( | color_func_type & | color_func | ) | [inline, protected] |
Get Axes Bitmaps and Update Textures. This method determines which coordinate axes planes that have changed. Only for the changed axes are bitmaps retrieved and textures updated.
| color_func | A color function funtor. This functor is used to translate the grid values from the cross section into color values (RGBA values stored as a (255,255,255,255) color format). |
| void OpenTissue::gl::CrossSections< grid_type >::get_i_cut | ( | color_func_type & | color_func | ) | [inline, protected] |
Get Axis Bitmap and Update Texture. This method retrives the cross intersection with the x-axis plane. The cross intersection is stored in the corresponding axis bitmap and then the corresponding texture is updated with the content of the bitmap.
| color_func | A color function funtor. This functor is used to translate the grid values from the cross section into color values (RGBA values stored as a (255,255,255,255) color format). |

| void OpenTissue::gl::CrossSections< grid_type >::init | ( | grid_type const & | grid | ) | [inline] |
Initialization. This method should be invoked before any visualization takes place. The method will allocate and initialize any internal data structures that is needed for the cross section visualization.
Observe that this class is completely bound to one grid. If one has multiple grids that need to be visualized. Then a seperate instance of this class is needed for each visualization wanted.
| grid | The grid that should be visualized. |
| void OpenTissue::gl::CrossSections< grid_type >::invalidate | ( | ) | [inline] |
Invalidate Visualization. Invoking this method will force the visualization to re-fetch all cross intersections and store them in textures. The following draw-invokation will then be a complete re-draw of the data.
It is generally a good idea to invoke this method when data stored in the grid volume is altered.
