Detailed Description

Uses basic self-repairing state control inside create_texture, delete_texture, drop_texture loop. Calling create_texture second time will automatically delete previous texture. Constructors and destructors don't create or delete texture, so this should be done by a wrapper class, otherwise, it's a leak.

RenderTarget should be set to valid value when calling this from draw method.

Member Function Documentation

◆ CreateTexture()

void iv::GlTexture::CreateTexture	(	Context const *	logger,
		RenderTarget *	target,
		int2	size,
		GlMinFiltering	min,
		GlMagFiltering	mag,
		bool	repeat,
		PixelFormat	storage_format,
		ColorSpace	color_space
	)

Creates (or recreated) texture in opengl context. Texture is stored using given PixelFormat.

Definition at line 50 of file GlTexture.cpp.

◆ LoadData()

void iv::GlTexture::LoadData	(	Context const *	logger,
		RenderTarget *	target,
		uint8_t *	values,
		size_t	values_size,
		PixelFormat	data_format
	)

The data_format can be different than the format used in CreateTexture - data will be transformed, but performance warning will be printed to log.

◆ DestroyTexture()

void iv::GlTexture::DestroyTexture	(	Context const *	logger,
		RenderTarget *	target
	)

Definition at line 122 of file GlTexture.cpp.

◆ DropTexture()

void iv::GlTexture::DropTexture	(	Context const *	logger,
		RenderTarget *	target
	)

Disassocieates GLuint texture_id from this instance without destroying it.

◆ allocated()

bool iv::GlTexture::allocated ( ) const

Definition at line 45 of file GlTexture.cpp.

◆ size()

int2 iv::GlTexture::size ( ) const

Definition at line 35 of file GlTexture.cpp.

◆ texture_id()

GLuint iv::GlTexture::texture_id ( ) const

Definition at line 40 of file GlTexture.cpp.

◆ gpu_color_space()

ColorSpace iv::GlTexture::gpu_color_space ( ) const

Color space in shaders = in which colorspace will texels be when fetched in shader.
