Title: The Legacy of OpenGL 2.0: Bridging the Fixed-Function Past and the Programmable Future

Hardware That Defined OpenGL 2.0

• NVIDIA GeForce 6 series (2004): The first to fully support OpenGL 2.0 hardware-accelerated shaders.
• ATI Radeon X800 series: Excellent GLSL performance, though some edge cases required vendor-specific workarounds.
• Apple Power Mac G5 + NVIDIA 6800 Ultra: OpenGL 2.0 brought workstation-class 3D to creative pros running macOS.

2. The Limitations of the Fixed-Function Pipeline

Prior to version 2.0, OpenGL operated on a rigid pipeline. Vertices were transformed, lighting was calculated via the Phong reflection model, and textures were mapped via fixed operations. opengl 20

1. Create vertex and fragment shader objects.
2. Compile GLSL source code.
3. Link them into a shader program.
4. Use glUseProgram(programID).
5. Set uniforms (matrices, lights) and attributes (positions, normals).

, allowing developers to write custom vertex and fragment shaders for more realistic lighting and special effects. Rendering Capabilities : Introduced Multiple Render Targets (MRT) Title: The Legacy of OpenGL 2
