| 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. |

Instead of standard Emscripten, use the Rexo compiler:

OpenGL serves as a cross-platform, industry-standard API for high-performance 2D and 3D graphics rendering by interfacing directly with the GPU. Modern implementations (3.3+) focus on programmable pipelines, utilizing shaders and buffer objects for hardware-accelerated graphics. For a comprehensive guide, visit LearnOpenGL.com .
