Detailed Description

Wraps an OpenGL texture object.

Can be created from an image file on disk or from a raw pixel buffer (e.g. a glyph atlas), then bound for sampling in a shader.

Constructor & Destructor Documentation

Texture() [1/2]

cangine::Texture::Texture

(

)

Constructs an empty texture without loading any data.

Texture() [2/2]

cangine::Texture::Texture

(

std::string

path

)

Constructs a texture from an image file path (not yet loaded).

Parameters

path	Path to the image file.

Member Function Documentation

bind()

void cangine::Texture::bind

(

)

Binds this texture for sampling.

createFromBuffer()

void cangine::Texture::createFromBuffer	(	int	width,
		int	height,
		unsigned char *	data,
		bool	mono = false
	)

Creates a texture from a raw pixel buffer.

Parameters

width	Width of the buffer in pixels.
height	Height of the buffer in pixels.
data	Pointer to the pixel data.
mono	If true, treat the data as a single-channel image.

load()

void cangine::Texture::load

(

)

Loads the image at path into GPU memory.

unbind()

void cangine::Texture::unbind

(

)

Unbinds the current texture.

update()

void cangine::Texture::update

(

std::string

path

)

Replaces the texture's source image and reloads it.

Parameters

path	Path to the new image file.

Member Data Documentation

ID

unsigned int cangine::Texture::ID

OpenGL texture object handle.

path

std::string cangine::Texture::path

Path of the source image, if loaded from a file.
