Hi, I'm trying to use lispbuilder with cl-opengl. Specifically, I'm trying to convert a texture example from C++ into lisp [1].
I ran into a little trouble when the example got the pixels from the surface: surface->pixels What I eventually got working in lisp is: (sdl-base::with-pixels (pixels (sdl:fp surface)) (sdl-base::pixel-data pixels)) Which seems to work ok. (But I'd still like confirmation that this is the best way to do it. It seems like too much code to do something so simple.) My second question is about how to free the texture after I'm done. I know this isn't really an SDL thing, but I figured you dealt with this when you created lisp wrappers around SDL surfaces. My intuition would be to create a finalizer for the wrapper, and free the texture then. But according to trivial-garbage [2], in some lisps it isn't safe to use an object when the finalizer is called. (Or does CFFI do this automatically for me?) Thanks. Any advice would be appreciated.
