rendertarget_id(3) Arcan Lua API rendertarget_id(3) NAME rendertarget_id - Assign a numeric identifier to a rendertarget SYNOPSIS id or nil rendertarget_id( vid:rtgt ) rendertarget_id( vid:rtgt, int:id ) DESCRIPTION This function is intended to be used for the rendering cases where a shader need to distinguish between the destination rendertarget, e.g. the case when stereoscopically rendering a side-by-side packed textured source with- out manually managing multiple pipelines. To do this, create two rendertar- gets, one via define_rendertarget and the other via define_linktarget . Give each a unique identifier with the help of this function, and then write your shader so that it does this distinction via the builtin int uni- form rtgt_id. The two forms of this function is simply one that retrieves the current identifier, and another that updates. If the vid specified with rtgt does not exist, nil will be returned.
