GLScene is a free OpenGL-based library for Delphi, C++ and Free Pascal. It provides visual components and objects allowing description and rendering of 3D scenes.

Development of the original library was started in 1999 by Mike Lischke [2] and at version 0.5 the library was made Open Source and placed in the care of project administrator Eric Grange.

GLScene allows programmers to create OpenGL 3D objects at design-time using the interface shown. A wide range of objects and additional VCL controls are provided to help the programmer to build powerful 3D Delphi applications.

GLScene is supported by its user-base and comes with a number of demonstration applications and examples. Beginning with version 1.2 it also supports the C++Builder and Lazarus IDE for Free Pascal.

Pascal is an imperative and procedural programming language, designed by Niklaus Wirth as a small, efficient language intended to encourage good programming practices using structured programming and data structuring. It is named in honour of the French mathematician, philosopher and physicist Blaise Pascal.

Turbo Pascal is a software development system that includes a compiler and an integrated development environment (IDE) for the Pascal programming language running on CP/M, CP/M-86, and DOS. It was originally developed by Anders Hejlsberg at Borland, and was notable for its extremely fast compilation. Turbo Pascal, and the later but similar Turbo C, made Borland a leader in PC-based development.

The Windows API, informally WinAPI, is Microsoft's core set of application programming interfaces (APIs) available in the Microsoft Windows operating systems. The name Windows API collectively refers to several different platform implementations that are often referred to by their own names ; see the versions section. Almost all Windows programs interact with the Windows API. On the Windows NT line of operating systems, a small number use the Native API.

C++Builder is a rapid application development (RAD) environment, originally developed by Borland and as of 2009 owned by Embarcadero Technologies, for writing programs in the C++ programming language currently targeting Windows, iOS and for several releases, macOS and Android C++Builder combines the Visual Component Library and IDE written in Object Pascal with multiple C++ compilers. Most components developed in Delphi can be used in C++Builder with no or little modification, although the reverse is not true, but this constraint is valid only for source code. Binary code generated by Delphi can easily be linked to binary code generated by C++Builder and vice versa to generate an executable written in both Object Pascal and C++. With this approach, C++ can be called from Object Pascal and vice versa. Since both Delphi and C++ use the same back end linker, the debugger can single step from Delphi code into C++ transparently.

The Visual Component Library (VCL) is a visual component-based object-oriented framework for developing the user interface of Microsoft Windows applications. It is written in Object Pascal.

Delphi is a general-purpose programming language and a software product that uses the Delphi dialect of the Object Pascal programming language and provides an integrated development environment (IDE) for rapid application development of desktop, mobile, web, and console software, currently developed and maintained by Embarcadero Technologies.

Open Inventor, originally IRIS Inventor, is a C++ object-oriented retained mode 3D graphics toolkit designed by SGI to provide a higher layer of programming for OpenGL. Its main goals are better programmer convenience and efficiency. Open Inventor exists as both proprietary software and free and open-source software, subject to the requirements of the GNU Lesser General Public License (LGPL), version 2.1.

Irrlicht is an open-source game engine written in C++. It is cross-platform, officially running on Windows, macOS, Linux and Windows CE and due to its open nature ports to other systems are available, including FreeBSD, Xbox, PlayStation Portable, Symbian, iPhone, AmigaOS 4, Sailfish OS via a QT/Qml wrapper, and Google Native Client.

Object Pascal is an extension to the programming language Pascal that provides object-oriented programming (OOP) features such as classes and methods.

<span class="mw-page-title-main">Free Pascal</span> Free compiler and IDE for Pascal and ObjectPascal

Free Pascal Compiler (FPC) is a compiler for the closely related programming-language dialects Pascal and Object Pascal. It is free software released under the GNU General Public License, with exception clauses that allow static linking against its runtime libraries and packages for any purpose in combination with any other software license.

Borland Kylix is a compiler and integrated development environment (IDE) formerly sold by Borland, but later discontinued. It is a Linux software development environment based on Borland Delphi and Borland C++ Builder, which runs under Microsoft Windows. Continuing Delphi's classical Greek theme, Kylix is the name for an ancient Greek drinking cup. The closest supported equivalent to Kylix is the free Lazarus IDE package, designed to be code-compatible with Delphi. As of 2010 the project has been resurrected in the form of Delphi cross compiler for Mac and Linux, as shown in the Embarcadero's Delphi and C++ Builder roadmap. As of September 2011 with Kylix discontinued the framework for cross-platform development by Embarcadero is FireMonkey.

<span class="mw-page-title-main">Lazarus (software)</span> Free cross-platform integrated development environment for Free Pascal

Lazarus is a free cross-platform visual integrated development environment (IDE) for rapid application development (RAD) using the Free Pascal compiler. Its goal is to provide an easy-to-use development environment for programmers developing with the Object Pascal language, which is as close as possible to Delphi.

In Microsoft Windows applications programming, OLE Automation is an inter-process communication mechanism created by Microsoft. It is based on a subset of Component Object Model (COM) that was intended for use by scripting languages – originally Visual Basic – but now is used by several languages on Windows. All automation objects are required to implement the IDispatch interface. It provides an infrastructure whereby applications called automation controllers can access and manipulate shared automation objects that are exported by other applications. It supersedes Dynamic Data Exchange (DDE), an older mechanism for applications to control one another. As with DDE, in OLE Automation the automation controller is the "client" and the application exporting the automation objects is the "server".

Internet Direct, also known as "Indy", is a free software / open source socket library written in Object Pascal, an object-oriented version of Pascal. It includes clients, servers, TCP, UDP, and raw sockets, as well as over 100 higher level protocols implementations such as SMTP, POP3, NNTP, and HTTP. Indy includes support for OpenSSL and Zlib in the protocol implementations. Indy 10 was ported to Free Pascal, and runs on Windows, FreeBSD, Linux, and Darwin.

<span class="mw-page-title-main">FireMonkey</span>

FireMonkey is a cross-platform GUI framework developed by Embarcadero Technologies for use in Delphi or C++Builder, using Object Pascal or C++ to build cross platform applications for Windows, macOS, iOS, and Android. A 3rd party library, FMX Linux, enables the building of FireMonkey applications on Linux.

Smart Pascal is a dialect of the Object Pascal computer language that is derived from Delphi Web Script, but is enhanced and adapted for Smart Mobile Studio, a commercial development suite that generates JavaScript rather than machine code.
