<pre class="sourcecodebox">Introduction:
This sample code demonstrates how to load, compile, and link GLSL fragment and
vertex shaders from within a simple Cocoa application.
The Fragment and vertex shaders have c like syntax and reside in the files with
".vs" and ".fs" extensions respectively, inside the main application bundle.
They're loaded, compiled, linked and bound to a program object using OpenGL APIs
and instantiated through the Shader class. The shader class here does not
validate the program object.
This project further contains a simple class for displaying strings in an
OpenGL view using GLUT's built-in bitmap fonts.
This application further demonstrates a simple timer based OpenGL animation
from within a Cocoa application.
It is also worth noting that the Tranguloid Trefoil geometry here is a
parametric surface, created using a display list.
Mouse support:
* For zooming the object, hold the right-mouse down and move mouse up or down.
* For updating the pitch, hold the left-mouse key down and change the angle.
Revision History:
* Refactored the sample code to better demonstrate the interaction of OpenGL
APIs with an OpenGL view.
* Moved the GLSL program object instantiation into its own basic class.
* Moved the GLSL hardware check code into its a separate file.
* Consistent use of float math library functions for pattern and palette
generation.
* Animation continues during window resizing.
* Consistent use of doubles and their OpenGL equivalents during geometry
generation.
* Updated the Xcode project to use the new format.
* Updated the NIB to use the new format.
* Added a simple GLUT string class.</pre>
