Js-visg-m-s | Manual

| Error Code | Message | Likely Cause & Solution | |------------|---------|------------------------| | E-1001 | INVALID_CANVAS_ID | The canvas selector does not exist. Check DOM readiness. | | E-2104 | SHADER_COMPILATION_FAIL | GPU does not support required precision. Fallback to precision lowp float in shader header. | | E-3207 | M-S_BUFFER_OVERRUN | Incoming data rate > 60 updates/sec. Implement throttling or increase maxStreamLag . | | E-4420 | TEXTURE_DIM_MISMATCH | Texture size not power of two (e.g., 513x513). Resize to 512x512. | React Example import useEffect, useRef from 'react'; import SceneManager from 'js-visg-m-s'; function VisualizationPanel( data ) const canvasRef = useRef(null); const sceneRef = useRef(null);

// Import the module (ES6 syntax) import SceneManager, GeometryBuilder, ColorMap from 'js-visg-m-s'; // Step 1: Obtain a canvas element const canvas = document.getElementById('visg-canvas'); js-visg-m-s manual

// Step 3: Create a test geometry (a 64x64 heightfield) const terrain = GeometryBuilder.fromHeightmap( widthSegments: 64, depthSegments: 64, heightAmplitude: 2.5, textureRepeat: 4 ); | Error Code | Message | Likely Cause
