Unigine::Profiler Class

Header: #include <UnigineProfiler.h>

The Profiler class is used to create counters for the engine Performance Profiler. Allows using counters in your code in the following manner:

Source code (C++)
Profiler::get()->begin("my_counter");
// ...code to profile...
Profiler::get()->end();

Notice
Counters can be nested.

Usage Example#

The following example contains different approaches to creating counters:

  • Two counters are added via the setValue() function: one shows the number of dynamic mesh vertices, the other shows the update time. This approach should be used when you need to show, for example, a value of a setting, the number of objects, and so on.
  • Another two counters are added by using the begin()/end() construction. They shows the time spent for mesh grid modifying and the time spent for mesh normal vectors, tangent vectors and a mesh bounding box calculation. This approach should be used when you need to show time spent for executing a part of the code.

AppWorldLogic.h contains declaration of the required variables.

Source code (C++)
#include <UnigineLogic.h>
#include <UnigineStreams.h>
#include <UnigineObjects.h>

class AppWorldLogic : public Unigine::WorldLogic {

public:
	AppWorldLogic();
	virtual ~AppWorldLogic();
	
	virtual int init();
	
	virtual int update();
	virtual int render();
	virtual int flush();
	
	virtual int shutdown();
	virtual int destroy();
	
	virtual int save(const Unigine::StreamPtr &stream);
	virtual int restore(const Unigine::StreamPtr &stream);

private:
	// declare variables
	int size = 128;
	Unigine::ObjectMeshDynamicPtr mesh;
};

In AppWorldLogic.cpp, a dynamic mesh is created and then modified on the engine update. All counters are created on update() too.

Source code (C++)
#include "AppWorldLogic.h"
#include <UnigineProfiler.h>
#include <UnigineEditor.h>
#include <UnigineGame.h>

using namespace Unigine;

int AppWorldLogic::init() {

	// create a dynamic mesh
	mesh = ObjectMeshDynamic::create(ObjectMeshDynamic::DYNAMIC_VERTEX | ObjectMeshDynamic::IMMUTABLE_INDICES);
	// release script ownership
	mesh->release();
	// pass ownership to UnigineEditor
	Editor::get()->addNode(mesh->getNode());
	// set the mesh settings
	mesh->setWorldTransform(Math::translate(Math::Vec3(0.0f, 0.0f, 2.0f)));
	mesh->setMaterial("mesh_base", "*");

	// create dynamic mesh vertices
	for (int y = 0; y < size; y++) {
		for (int x = 0; x < size; x++)
		{
			mesh->addVertex(Math::vec3(0.0f));
			mesh->addTexCoord(Math::vec4((float)x / size, (float)y / size, 0.0f, 0.0f));
		}
	}
	
	// create dynamic mesh indices
	for (int y = 0; y < size - 1; y++) {
		int offset = size * y;
		for (int x = 0; x < size - 1; x++) {
			mesh->addIndex(offset);
			mesh->addIndex(offset + 1);
			mesh->addIndex(offset + size);
			mesh->addIndex(offset + size);
			mesh->addIndex(offset + 1);
			mesh->addIndex(offset + size + 1);
			offset++;
		}
	}

	return 1;
}

int AppWorldLogic::update() {
	
	// add a counter that shows engine update phase duration
	Profiler::get()->setValue("Update time", "ms", Engine::get()->getUpdateTime(), (float)NULL, Math::vec4(0.0f));

	float time = Game::get()->getTime();
	float isize = 30.0f / size;
	// start the counter that shows the time spent for dymanic mesh grid modifying
	Profiler::get()->begin("Grid", Math::vec4(1.0f));
	for (int y = 0; y < size; y++)
	{
		for (int i = 0; i < size; i++)
		{
			float Y = y * isize - 15.0f;
			float Z = Math::cos(Y + time);
			for (int x = 0; x < size; x++)
			{
				float X = x * isize - 15.0f;
				mesh->setVertex(i++, Math::vec3(X, Y, Z * Math::sin(X + time)));
			}
		}
	}
	// stop the counter
	Profiler::get()->end();
	
	// start the counter that shows the time spent for 
	// dynamic mesh normal vectors, tangent vectors and a mesh bounding box calculation
	Profiler::get()->begin("mesh");
	mesh->updateBounds();
	mesh->updateTangents();
	mesh->flushVertex();
	// stop the counter
	Profiler::get()->end();
	
	// add the counter that shows the number of dynamic mesh vertices
	Profiler::get()->setValue("Num vertices", "", mesh->getNumVertex(),NULL,NULL);
	
	return 1;
}

ObjectMeshDynamicPtr mesh;
// ...
// start the counter that shows the time spent for 
// dynamic mesh normal vectors, tangent vectors and a mesh bounding box calculation

Returns a pointer to the GUI of the engine Performance Profiler.

Return value

Pointer to the GUI.

Sets the GUI for the engine Performance Profiler.

Arguments

  • const Ptr<Gui> & gui - A pointer to the GUI class instance.

int beginMicro( const char * name )

Starts a counter with a given name in the Microprofile only, without overloading the Performance Profiler layout. The counter shows user how many millisecods have been spent for the operation that is peformed between the beginMicro() and the endMicro() functions.
Notice
Each counter has an ID. Thus, several nested beginMicro() / endMicro() blocks can be created, which can't be done in the Performance Profiler.
Source code (C++)
ObjectMeshDynamicPtr mesh;
// ...
// start the counter that shows the time spent for 
// dynamic mesh normal vectors, tangent vectors and a mesh bounding box calculation, with a nested counter for tangent vectors only
int c_id = Profiler::get()->beginMicro("mesh");
mesh->updateBounds();
int c_nested_id = Profiler::get()->beginMicro("mesh_tangents");
mesh->updateTangents();
Profiler::get()->endMicro(c_nested_id);
mesh->flushVertex();
// stop the counter
Profiler::get()->endMicro(c_id);

Arguments

  • const char * name - Name of the counter.

Return value

ID of the new added counter.

void endMicro( int id )
