WebGL Status
About
This tool performs a deep diagnostic of your browser's ability to render interactive 3D graphics via the WebGL API (Web Graphics Library). Unlike standard HTML rendering, WebGL allows the browser to communicate directly with your device's GPU (Graphics Processing Unit), unlocking hardware-accelerated performance for games, data visualization, and complex user interfaces.
We test for both WebGL 1.0 (based on OpenGL ES 2.0) and WebGL 2.0 (based on OpenGL ES 3.0). The report extracts critical hardware limits - such as the Max Texture Size and Shader Precision - which determine the complexity of scenes your device can handle. A functioning WebGL environment relies on a chain of trust: Valid HTML5 Browser → Up-to-date GPU Drivers → Hardware Acceleration Settings.
Formulas
While this tool is diagnostic, the underlying logic relies on Linear Algebra to project 3D coordinates onto your 2D screen. The Vertex Shader performs this transformation for every corner of the geometry:
Where P is the Perspective Projection Matrix, V is the View (Camera) Matrix, M is the Model (Rotation/Scale) Matrix, and vpos is the original vertex position in 3D space.
