Unigine::DecalOrtho Class

Header: #include <UnigineDecals.h>
Inherits: Decal

This class describes how to create and modify orthographic decals.

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 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:
	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, material to "decal_base"
	decal_ortho = DecalOrtho::create(10.0f, 2.0f, 2.0f, "decal_base");

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

	// release ownership of its pointer and add the node to UnigineEditor
	decal_ortho->release();
	Editor::get()->addNode(decal_ortho->getNode());

	return 1;
}

int AppWorldLogic::shutdown() {
	
	// clear pointer
	decal_ortho.clear();

	return 1;
}

DecalOrtho Class

Members


static DecalOrthoPtr create ( float radius, float width, float height, const char * material )

Constructor. Creates a new projected decal with the given properties.

Arguments

  • float radius - The height of the projection box along the Z axis, in units.
  • float width - The length of the projection box along the X axis, in units.
  • float height - The length of the projection box along the Y axis, in units.
  • const char * material - A material of the decal.

Ptr<DecalOrtho> cast( const Ptr<Decal> & base )

Casts a DecalOrtho out of the Decal instance.

Arguments

  • const Ptr<Decal> & base - Pointer to Decal.

Return value

Pointer to DecalOrtho.

Ptr<DecalOrtho> cast( const Ptr<Node> & node )

Casts a DecalOrtho out of the Node instance.

Arguments

  • const Ptr<Node> & node - Node smart pointer.

Return value

Pointer to the DecalOrtho.

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( )

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( )

Returns the projection matrix.

Return value

The projection matrix of the decal.

void setRadius( float radius )

Sets a new height of the projection box along the Z axis.

Arguments

  • float radius - A height of the projection box along the Z axis, in units. If a too small value is provided, 1E-6 will be used instead.

float getRadius( )

Returns the current height of the projection box along the Z axis.

Return value

The height of the projection box along the Z axis, in units.

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( )

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( )

Returns the value of the near clipping plane.

Return value

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

int type( )

Returns a type identifier.

Return value

Type identifier.
