By making these stages programmable using a C-like syntax, OpenGL 2.0 enabled visual effects that were previously impossible in real-time, such as per-pixel lighting, procedural textures, and advanced bump mapping. Key Features of OpenGL 2.0
: Controlling the color and light of every individual pixel. 2. Why Use OpenGL 2.0 in 2026?
// Create and compile fragment shader GLuint fragment_shader = glCreateShader(GL_FRAGMENT_SHADER); const char* fragment_shader_source = "#version 200\n" "out vec4 frag_color;\n" "void main() \n" " frag_color = vec4(1.0, 0.0, 0.0, 1.0);\n" "\n"; glShaderSource(fragment_shader, 1, &fragment_shader_source, NULL); glCompileShader(fragment_shader);
: The first version of the C-like shading language integrated directly into the core API. Programmability
