Integrating Canvas with WebGL for 3D graphics and visualizations Mocktest

WebGL stands for Web Graphics Library, which is a JavaScript API for rendering 2D and 3D graphics within a web browser.

The Canvas element provides a 2D drawing context in HTML5, allowing dynamic rendering of graphics and animations.

WebGL leverages the GPU (Graphics Processing Unit) for accelerated rendering, leading to high-performance graphics within web browsers.

WebGL primarily focuses on rendering 3D graphics and visualizations directly within web browsers.

WebGL is a JavaScript API based on OpenGL ES (Embedded Systems) and is used for rendering 2D and 3D graphics within web browsers.

The primary advantage of using WebGL for 3D graphics is its high-performance rendering capabilities, leveraging GPU acceleration for smooth and realistic visualizations.

In JavaScript, the getContext('webgl') function is used to obtain the WebGL context from a Canvas element, allowing WebGL rendering within that canvas.

Shaders in WebGL are used for customizing rendering pipelines, allowing developers to control how vertices and pixels are processed, leading to complex visual effects and realistic rendering.

The WebGLRenderingContext in WebGL is responsible for creating and compiling shaders, essential for defining custom rendering logic in WebGL applications.

Vertices and faces in WebGL geometry are typically defined using arrays of coordinates (vertices) and indices (faces), specifying the geometry and structure of 3D objects to be rendered.
