SceneGraphAnalyzerMeter

class SceneGraphAnalyzerMeter

Bases: TextNode

This is a special TextNode that automatically updates itself with output from a SceneGraphAnalyzer instance. It can be placed anywhere in the world where you’d like to see the output from SceneGraphAnalyzer.

It also has a special mode in which it may be attached directly to a channel or window. If this is done, it creates a DisplayRegion for itself and renders itself in the upper-right-hand corner.

SceneGraphAnalyzerMeter(SceneGraphAnalyzerMeter const&) = default

void clear_window(void)

Undoes the effect of a previous call to setup_window().

static TypeHandle get_class_type(void)

DisplayRegion *get_display_region(void) const

Returns the DisplayRegion that the meter has created to render itself into the window to setup_window(), or NULL if setup_window() has not been called.

PandaNode *get_node(void) const

Returns the node to be analyzed.

double get_update_interval(void) const

Returns the number of seconds that will elapse between updates to the frame rate indication.

GraphicsOutput *get_window(void) const

Returns the GraphicsOutput that was passed to setup_window(), or NULL if setup_window() has not been called.

void set_node(PandaNode *node)

Sets the node to be analyzed.

void set_update_interval(double update_interval)

Specifies the number of seconds that should elapse between updates to the meter. This should be reasonably slow (e.g. 0.5 to 2.0) so that the calculation of the scene graph analysis does not itself dominate the frame rate.

void setup_window(GraphicsOutput *window)

Sets up the frame rate meter to create a DisplayRegion to render itself into the indicated window.

void update(void)

You can call this to explicitly force the SceneGraphAnalyzerMeter to update itself with the latest scene graph analysis information. Normally, it is not necessary to call this explicitly.
