OpenGL (Open Graphics Library) is a cross-language, cross-platform application programming interface (API) used for rendering 2D and 3D vector graphics. It acts as a bridge between your application and the graphics processing unit (GPU), allowing you to leverage hardware acceleration for fast rendering. Key Characteristics

| Tip | Why it matters | |------|----------------| | | Each gl.useProgram , gl.bindTexture causes GPU pipeline stalls. | | Batch draw calls | Merge multiple objects into one buffer; use gl.drawElements with index buffers. | | Use vertex array objects (VAOs) | Store attribute configurations in one object (WebGL2+). | | Compress textures | Use WebP or basis-universal to reduce upload bandwidth. | | OffscreenCanvas + Web Worker | Perform heavy computations or even whole WebGL rendering off the main thread. | | Tip | Why it matters | |------|----------------|
