Member Function Documentation

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

Load an image from a file and create a new texture from it.

Parameters
filenamethe texture file name, can be absolute path if starts with '/' otherwise the file will be looked for in Stellarium's standard textures directories.
paramsthe texture creation parameters.
StelTextureSP StelTextureMgr::createTextureThread ( const QString &  url,
const StelTexture::StelTextureParams params = StelTexture::StelTextureParams(),
bool  lazyLoading = true 
)

Load an image from a file and create a new texture from it in a new thread.

Note
This method is safe to be called from threads other than the main thread.
Parameters
urlthe 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.
paramsthe texture creation parameters.
lazyLoadingdefine whether the texture should be actually loaded only when needed, i.e. when bind() is called the first time.
int StelTextureMgr::getGLMemoryUsage ( )

Returns the estimated memory usage of all textures currently loaded through StelTexture.

StelTextureSP StelTextureMgr::wrapperForGLTexture ( GLuint  texId)

Creates or finds a StelTexture wrapper for the specified OpenGL texture object.

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

Parameters
texIDThe 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.
