Detailed Description

The TextureManager loads and handles textures.

It is a singleton and can be accessed anywhere using its static instance. Currently only PNG textures are supported.

loadTexture() [1/2]

unsigned int sgct::TextureManager::loadTexture	(	const Image &	img,
		bool	interpolate = true,
		float	anisotropicFilterSize = 1.f,
		int	mipmapLevels = 8 )

Loads a texture to the TextureManager.

Parameters

img	The image with the texture data
interpolate	Set to true for using interpolation (bi-linear filtering)
anisotropicFilterSize	The filter size that is used for the anisotropic filtering. If this value is 1.f, only bilinear filtering is used
mipmapLevels	The number of mipmap levels that will be generated, setting this value to 1 or less disables mipmaps

Returns

The OpenGL name for the texture that was loaded

loadTexture() [2/2]

unsigned int sgct::TextureManager::loadTexture	(	const std::filesystem::path &	filename,
		bool	interpolate = true,
		float	anisotropicFilterSize = 1.f,
		int	mipmapLevels = 8 )

Loads a texture to the TextureManager.

Parameters

filename	The path to the texture
interpolate	Set to true for using interpolation (bi-linear filtering)
anisotropicFilterSize	The filter size that is used for the anisotropic filtering. If this value is 1.f, only bilinear filtering is used
mipmapLevels	The number of mipmap levels that will be generated, setting this value to 1 or less disables mipmaps

Returns

The OpenGL name for the texture that was loaded

removeTexture()

void sgct::TextureManager::removeTexture

(

unsigned int

textureId

)

Removes a previously generated OpenGL texture.

Parameters

textureId

The id of the texture that should be deleted, this has to be an id that was returned from a previous call to loadTexture
