To what is exposed through core functionality, so they should be Through ARB extensions and through core 2.0 specification.īasically, what is exposed through extensions is completely orthogonal Remove the extensions, and support only the 'core' functions.Īlso, sometimes when functionality is promoted from ARB extension intoĬore it's slightly changed (although in 99% cases it stays the same).Įxample is the GLSL shaders, that expose (very slightly) different API It supports the same functionality in core already. OpenGL doesn't have to support the extension entry points, even when AFAIK it has the same entry points as the core functionality and OpenGL versions are required to support the ARB version of functions even if the non ARB version is in the core now.Ī: No. quality of life, and adherence to treatment in a sample of Pascal Auquier 1 patients with schizophrenia. Usually unit names are listed in the clause. The modules listed in the clause have to be capable of exporting identifiers, that means a program name may not appear in the list. Q: I don't understand why the ARB version does not work. The uses clause consists of the word uses, followed by a comma -separated list of module names, which is terminated by a semicolon.

Castle Game Engine allows you to navigate and render 3D worlds (in VRML, X3D and other 3D formats).

GLScene is a Lazarus package with lots of extra features for OpenGL applications.

Basically it is the same as the system unit. If you want to modify TOpenGLControl implementation, for example to add new properties like ColorBits and AuxBuffers, see Extending TOpenGLControl. The system unit contains the standard supported functions of Free Pascal. An example can be found in lazarus/examples/openglcontrol/openglcontrol_demo.lpi. Contents 1 Purpose 2 Format 2. 2 Common multiple units of the pascal are the hectopascal (1 hPa 100 Pa), which is equal to one millibar, and the kilopascal ( Pa), which is equal to one centibar. It must appear before anything in the unit except comments. The unit of measurement called standard atmosphere (atm) is defined as 101,325 Pa.

The Lazarus package LazOpenGLContext can be found in lazarus/components/opengl/lazopenglcontext.lpk. A unit is a source code file (or the binary compiled from that file) which was written using the Pascal programming language, and that is designed to be a single module in an application or an object module. Lazarus includes a TOpenGLControl - a LCL control with an OpenGL context. Obviously, you cannot use this unit on non-X Window systems such as Windows. Free Pascal is also available on the start menu at Start -> Programs. Procedures always start with the preposition 'glx'. You may invoke the Free Pascal compiler by typing fpc program.pp at any command shell. glx: glx provides functionality to set up an OpenGL window in an X Window system.

Although this is a cross-platform unit, most Windows operating systems don't have a glut dll by default.

glut: This unit provides functionality for creating an OpenGL window.

If your OpenGL library version is older than X.Y, Load_GL_version_X_Y will return false. Initializing this functionality is similar to initializing normal OpenGL extensions: just call Load_GL_version_X_Y function. The functionality specific to higher OpenGL versions (1.2 and later) is available in this unit as well.

glext: Vendors can provide additional functionality through extensions.

Procedures always start with the preposition 'glu'. Although it has some useful functions, this unit is not necessary as you can implement all glu Procedures with the functionality of the gl unit. Procedures always start with the preposition 'gl'.

gl: This unit contains the main functionality such as drawing polygons, applying transformations, setting colors and materials.

The Free Pascal OpenGL interface consists of the following units:
