- Purpose:
The purpose of GTK+OGLTK is to simplify creating 3D and 2D applications using OpenGL under the Gtk+2.x Application framework.
Using the GObject and signal framework from glib 2.x with Gtk+-2.x and Gtkglext this toolkit provides programmer with an easy to use API to create and manage 3D objects and scenes within a GTK Application.
This library is written in C because SandorLabs wants as many people to benifit using this library as possible. The abstarct GObject framework provides C programmers with an object oriented system. A C++ version of OGTLK can be undertaken by anyone who wishes since SandorLabs has no plans on taking on that project. However anyone doing so, SandorLabs requests it fall under the LGPL to keep license compatability.
2) About
- What Gtk+-OGLTK stand for?
- OGLTK stands for OpenGL Toolkit.
- What is ogltk_view?
Every application using the OGLTK requires this object. It is the only class which returns a GtkWidget . This widgets is then attached to a GtkWindow or inside a window container.
- What is ogltk_globject (GLobject)?
Don't be fooled, it looks like GObject but it's GLobject which stands for Graphic Library Object. This is an abstract class which is used to create 3D objects within a scene.
- What is a ogltk_scene?
It is not nescessary to use this class, but why wouldn't you, It provides a mechanism to place GLobjects within a scene. A gltk_scene maybe attached to a ogltk_view and called when the method ogltk_view_render is called. The ogltk_scene also has a signal which can be used by your appliation to give the frames per second at timed intervals you specify.
- I don't understand some of the source file prefixes.
- ogltk = OpenGL ToolKit Class (eg. ogltk_view.c ogltk_scene.c)
- glo = GLObject (eg. glo_cube.c glo_box.c)
- glt = GL Type (eg. glt_matrix.c , glt_color.c)

6) SandorLabs and the LGPL
SandorLabs supports the opensource community and especially the LGPL. The action of sharing source and libraries without the restriction of publishing all intellectual property from a project but any changes to the library (bugfixes, new features) are published back for all to use is more then acceptable.
