Unigine::DecalOrtho Class

Creating an Orthographic Decal#

The following code illustrates how to create an orthographic decal, set its parameters and add the node to UnigineEditor.

Source code (C++)

// AppWorldLogic.h

#include <UnigineLogic.h>
#include <UnigineEditor.h>
#include <UnigineDecals.h>

class AppWorldLogic : public Unigine::WorldLogic {
	
public:
	AppWorldLogic();
	virtual ~AppWorldLogic();
	
	virtual int init();
	
	virtual int update();
	virtual int postUpdate();
	virtual int updatePhysics();
	
	virtual int shutdown();
	
	virtual int save(const Unigine::StreamPtr &stream);
	virtual int restore(const Unigine::StreamPtr &stream);

private:
	Unigine::DecalOrthoPtr decal_ortho;
};

Source code (C++)

// AppWorldLogic.cpp

#include "AppWorldLogic.h";

using namespace Unigine;

int AppWorldLogic::init()
{

	// create an ortho decal and setting its radius to 10, width and height to 2
	decal_ortho = DecalOrtho::create();
	decal_ortho->setRadius(10.0f);
	decal_ortho->setWidth(2.0f);
	decal_ortho->setHeight(2.0f);

	// set the name and position of the decal
	decal_ortho->setName("Ortho Decal");
	decal_ortho->setWorldPosition(Math::Vec3(0.0f, 0.0f, 5.0f));

	return 1;
}

DecalOrtho Class

Members

static DecalOrthoPtr create ( ) #

Constructor. Creates a new orthographic decal with default parameters.

void setHeight ( float height ) #

Sets a new length of the projection box along the Y axis.

Arguments

float height - The length of the projection box along the Y axis, in units. If a negative value is provided, 0 will be used instead.

float getHeight ( ) const#

Returns the current length of the projection box along the Y axis.

Return value

The length of the projection box along the Y axis, in units.

Math::mat4 getProjection ( ) const#

Returns the projection matrix.

Return value

The projection matrix of the decal.

void setWidth ( float width ) #

Sets the new length of the projection box along the X axis.

Arguments

float width - The length of the projection box along the X axis, in units. If a negative value is provided, 0 will be used instead.

float getWidth ( ) const#

Returns the current length of the projection box along the X axis, in units.

Return value

The length of the projection box along the X axis, in units.

void setZNear ( float znear ) #

Sets a new value of the near clipping plane.

Arguments

float znear - A value of the near clipping plane, ranging from 0 to 1. If a negative value is provided, 0 will be used instead.

float getZNear ( ) const#

Returns the value of the near clipping plane.

Return value

The value of the near clipping plane, ranging from 0 to 1.

static int type ( ) #

Returns a type identifier.

Return value

Type identifier.
