VisuSurfaces object can be drawn with this class. Simply
create a new VisuGlExtSurfaces object and add surfaces with
visu_gl_ext_surfaces_add(). It is better to add several surfaces to
a single VisuGlExtSurfaces object since all vertices are reordered
when necessary to ensure proper transparency.
#define VISU_GL_EXT_SURFACES_ID "Surfaces"
The id used to identify this extension, see
visu_gl_ext_rebuild() for instance.
struct VisuGlExtSurfacesClass {
VisuGlExtClass parent;
};
A short way to identify _VisuGlExtSurfacesClass structure.
VisuGlExtClass |
the parent class; |
Since 3.7
gboolean visu_gl_ext_surfaces_add (VisuGlExtSurfaces *surfaces,VisuSurfaces *surf);
Add a new surface to the list of drawn surfaces.
|
a VisuGlExtSurfaces object. |
|
a VisuSurfaces object. [transfer full] |
Returns : |
FALSE if surf was already reguistered. |
Since 3.7
void visu_gl_ext_surfaces_draw (VisuGlExtSurfaces *surfs);
Rebuild each visible surface's list. The order in which to draw the surfaces
is given in the order argument. If the resource 'isosurfaces_drawIntra' is TRUE
then, the interior of the surfaces is drawn as color inverse.
|
a VisuGlExtSurfaces object. |
Since 3.7
VisuGlExtSurfaces * visu_gl_ext_surfaces_getDefault (void);
V_Sim is using a default surfaces object.
Returns : |
a VisuGlExtSurfaces object used by default. [transfer none] |
Since 3.7
gboolean visu_gl_ext_surfaces_getDrawIntra (VisuGlExtSurfaces *surfs);
Retrieve if the interiors of surfaces are drawn with a colour inverse or not.
|
a VisuGlExtSurfaces object. |
Returns : |
TRUE if the interior is painted in colour inverse. |
VisuGlExtSurfaces * visu_gl_ext_surfaces_new (const gchar *name);
Creates a new VisuGlExt to draw surfaces.
|
the name to give to the extension (default is VISU_GL_EXT_SURFACES_ID). [allow-none] |
Returns : |
a pointer to the VisuGlExt it created or NULL otherwise. |
Since 3.7
gboolean visu_gl_ext_surfaces_remove (VisuGlExtSurfaces *surfaces,VisuSurfaces *surf);
Removes surf from the list of drawn surfaces.
|
a VisuGlExtSurfaces object. |
|
a VisuSurfaces object. |
Returns : |
TRUE if visu_gl_ext_surfaces_draw(à should be called. |
Since 3.7
gboolean visu_gl_ext_surfaces_setDrawIntra (VisuGlExtSurfaces *surfs,gboolean status);
Set if the interiors of surfaces are drawn with a colour inverse or not.
|
a VisuGlExtSurfaces object. |
|
a boolean. |
Returns : |
TRUE if calling routine should redraw the surfaces with
visu_gl_ext_surfaces_draw(). |
gboolean visu_gl_ext_surfaces_setOnObserveOrdering (VisuGlExtSurfaces *surfaces,VisuInteractive *inter);
Attach surfaces to inter, so it can be rendered there. See visu_gl_ext_surfaces_draw().
|
the VisuGlExtSurfaces object to attached to rendering inter. |
|
a VisuInteractive object. [transfer full][allow-none] |
Returns : |
TRUE if visu_gl_ext_surfaces_draw() should be called and then 'OpenGLAskForReDraw'
signal be emitted. |
Since 3.7
gboolean visu_gl_ext_surfaces_setOnTheFlyOrdering (VisuGlExtSurfaces *surfaces,VisuGlView *view);
Attach surfaces to view, so it can be rendered there. See visu_gl_ext_surfaces_draw().
|
the VisuGlExtSurfaces object to attached to rendering view. |
|
a VisuGlView object. [transfer full][allow-none] |
Returns : |
TRUE if visu_gl_ext_surfaces_draw() should be called and then 'OpenGLAskForReDraw'
signal be emitted. |
