pointer to function;; pointer to member function;; functor;; lambda expression.; std::function is a template class that can hold any callable object that matches its signature.; In C++, any class that overloads the function call operator operator() may be called using function-call syntax.
Free and open-source software portal; Slic3r is free software 3D slicing engine for 3D printers.It generates G-code from 3D CAD files (STL or OBJ). Once finished, an appropriate G-code file for the production of the 3D modeled part, or object is sent to the 3D printer for the manufacturing of a physical object.
A slicer is a toolpath generation software used in 3D printing.It facilitates the conversion of a 3D object model to specific instructions for the printer. The slicer converts a model in STL (stereolithography) format into printer commands in G-code format.
In version 4, the core application is implemented in C++, and the API is available through a Python wrapper to facilitate rapid, iterative development and visualization in the included Python console. The user interface is implemented in Qt, and may be extended using either C++ or Python. [18] Slicer supports several types of modular development.
Once finished, the g-code can be sent to the printer for the manufacture of the physical object. [ 8 ] The open source software, compatible with most desktop 3D printers, can work with files in the most common 3D formats such as STL , OBJ , X3D , 3MF as well as image file formats such as BMP , GIF , JPG , and PNG .
Let C be a category with finite products and a terminal object 1. A list object over an object A of C is: an object L A, a morphism o A : 1 → L A, and; a morphism s A : A × L A → L A; such that for any object B of C with maps b : 1 → B and t : A × B → B, there exists a unique f : L A → B such that the following diagram commutes:
In Python, functions are first-class objects, just like strings, numbers, lists etc. This feature eliminates the need to write a function object in many cases. Any object with a __call__() method can be called using function-call syntax. An example is this accumulator class (based on Paul Graham's study on programming language syntax and ...
In many object-oriented languages, objects are represented internally in two parts. The object is stored as a block of data placed on the heap, while the name (or "handle") to that object is represented by a pointer. Objects are passed between methods by copying the value of the pointer, allowing the same underlying data on the heap to be ...
