Member Function Documentation

StelTextureSP StelTextureMgr::createTexture	(	const QString &	filename,
		const StelTexture::StelTextureParams &	params = `StelTexture::StelTextureParams()`
	)

Parameters

filename	the texture file name, can be absolute path if starts with '/' otherwise the file will be looked for in Stellarium's standard textures directories.
params	the texture creation parameters.

StelTextureSP StelTextureMgr::createTextureThread	(	const QString &	url,
		const StelTexture::StelTextureParams &	params = `StelTexture::StelTextureParams()`,
		bool	lazyLoading = `true`
	)

Note: This method is safe to be called from threads other than the main thread.

Parameters

url	the texture file name or URL, can be absolute path if starts with '/' otherwise the file will be looked for in Stellarium's standard textures directories.
params	the texture creation parameters.
lazyLoading	define whether the texture should be actually loaded only when needed, i.e. when bind() is called the first time.

StelTextureSP StelTextureMgr::wrapperForGLTexture ( GLuint texId )

The wrapper takes ownership of the texture and will delete it if it is destroyed.

Parameters

texID The OpenGL texture ID which should be wrapped. If this is already a StelTexture, the existing wrapper will be returned.

Returns: the existing or new wrapper for the texture with the given GL name. Returns a null pointer if the texture name is invalid.
