Detailed Description

This class manages textures.

This class contains functionality for loading textures from JPEG files
as well as creating empty textures for rendering.

Definition at line 19 of file Texture.h.

Constructor & Destructor Documentation

vis2::Texture::Texture ( )

inline

Empty constructor.

Definition at line 23 of file Texture.h.

Texture::Texture

(

const std::string &

_str_path

)

Constructor for creating a texture from a JPEG file.

This constructor laods the texture to the Graphics Card
and defines interpolation parameters and calls mipmap generation.

Parameters

[in]

_str_path

is the path to the JPEG file

Definition at line 6 of file Texture.cpp.

Texture::Texture	(	const unsigned int	_width,
		const unsigned int	_height,
		const unsigned int	_type
	)

Constructor for creating an empty texture for rendering.

Color textures have GLRGB8 or GL_RGBA8 format, depth textures have GL_DEPTH_COMPONENT32F format.

Parameters

[in]	_width	is the width of the new texture,
[in]	_height	is the height of the new texture,
[in]	_type	can be VIS2_TEX_TYPE_RGB, VIS2_TEX_TYPE_RGBA or VIS2_TEX_TYPE_DEPTH.

Definition at line 30 of file Texture.cpp.

Texture::~Texture

(

)

Destructor.

Definition at line 73 of file Texture.cpp.

vis2::Texture::Texture ( const Texture &  )

private

unsigned int vis2::Texture::getTextureWidth ( ) const

inline

getter for the texture attributes: width

Returns

Definition at line 57 of file Texture.h.

static void vis2::Texture::initDevIL ( )

static

Function for calling the DevIL library.

void Texture::loadTextureFromFile ( const std::string  _file_path )

private

Hidden copy-constructor.

Parameters

[in]

is

the path to the file on the local system

Definition at line 106 of file Texture.cpp.

void Texture::textureBind

(

const int

_unit

)

This function binds texture as a source.

Definition at line 81 of file Texture.cpp.

void Texture::textureBind2FBO

(

const int

_unit

)

This function binds texture to a bound FBO as a rendering target.

Parameters

[in]

_unit

is the id of the color or depth attachment, to which to bind the texture

Definition at line 87 of file Texture.cpp.

Member Data Documentation

private

is the id of this texture data as implemented by DevIL

Definition at line 67 of file Texture.h.

GLuint vis2::Texture::texture_handle

private

is the id of this texture on the Graphics Card

Definition at line 70 of file Texture.h.

unsigned int vis2::Texture::texture_height

private
