Detailed Description

This class produces quads for post-processing purposes.

Constructor & Destructor Documentation

QuadTextured::QuadTextured	(	glm::mat4	_modelMatrix,
		ShaderController *	_shader_ctrl,
		bool	_b_fill_window
	)

Constructor.

The geometry definition is contained in this class.

Parameters

[in]	_modelMatrix	is the object model matrix,
[in]	_shader_ctrl	is the shader controller for passing information btw geometry and environment,
[in]	_b_fill_window	is true, if the quad should be rendered over the entire window, false - if it should occupy the upper left quarter for debugging output.

Definition at line 5 of file QuadTextured.cpp.

QuadTextured::~QuadTextured ( )

virtual

Destructor.

Deletes the VBOs and the VAO built in the constructor.

Definition at line 55 of file QuadTextured.cpp.

vis2::QuadTextured::QuadTextured ( const QuadTextured &  )

private

Hidden copy-constructor.

Member Function Documentation

void QuadTextured::draw ( glm::mat4 &  _projectionMatrix )

virtual

The standard drawing function.

Calls draw(glm::mat4 & _projectionMatrix, glm::vec3 _edge_color).

Parameters

[in]

_projectionMatrix

passes the combined view and projectino matrices.

Implements vis2::DrawableObject.

Definition at line 71 of file QuadTextured.cpp.

void QuadTextured::draw	(	glm::mat4 &	_projectionMatrix,
		glm::vec3	_edge_color
	)

A drawing function for drawing with particular edge color when using edge detecting shaders.

This function activates the shader program, passes the updates to the shader uniform variables,
binds the Vertex Attribute Object (VAO), makes a draw call, then unbinds both the VAO and the shader program.

Parameters

[in]	_projectionMatrix	is the camera projection matrix,
[in]	_edge_color	is the edge color to be used.

Definition at line 76 of file QuadTextured.cpp.

void QuadTextured::update ( double  _deltaT )

virtual

Empty update function.

Implements vis2::DrawableObject.

Definition at line 67 of file QuadTextured.cpp.
