This example demonstrates WebGL’s ability to generate a gradient directly on the GPU, where the fragment shader colors each pixel based on its x and y coordinates relative to the canvas size. Using a minimal vertex shader and a full-screen triangle fan, it renders a smooth color transition without any external data. The code compiles and links shaders manually via the WebGL API, sets uniform and attribute locations, and calls `drawArrays` to produce the final image.

Part three of my introduction to WebGL, wherein the fragment shader computes the color based on the fragment coordinates.

Hello WebGL II

This example demonstrates vertex-color interpolation in WebGL by rendering a square with different colors bound to each corner. Using the canvas element’s WebGL context, it compiles separate vertex and fragment shaders as text. The shaders define a `varying` color variable that smoothly interpolates RGBA values across the shape. The code explicitly binds two vertex attribute arrays—positions and colors—and draws the square as a triangle fan, illustrating low-level GPU rendering without external libraries.

Hello WebGL

This example shows a solid green square rendered across the entire canvas using raw WebGL, with no external utility libraries or dependencies. The code manually compiles a vertex shader and a fragment shader from embedded script tags, creates a program, and defines a position buffer with four corner coordinates. It draws the square as a triangle fan using `context.drawArrays`, targeting a WebGL context obtained via `canvas.getContext("webgl")` with a fallback to `experimental-webgl`.

regl-demo

A WebGL triangle rendered with regl animates its background color in a smooth, time-based loop. The vertex shader derives the triangle’s fragment color from its position attributes, producing a gradient across the shape. The example uses `regl.frame` for continuous rendering and `regl.clear` to update the background, demonstrating basic GLSL shader setup and attribute passing with the regl API.

Hello WebGL IV

This example demonstrates WebGL fragment shaders rendering a digital image of a mandrill onto a canvas. The page compiles a vertex shader and a fragment shader, then uses the shader program to display the image as a texture on a square. It pulls the image data from a local `mandrill.jpg` file and uses the Canvas `getContext("webgl")` API to draw the textured quad with a `TRIANGLE_FAN`. The code explicitly manages buffers, shaders, and textures through the low-level WebGL context.

Simple Water Simulation

This example shows a simple water simulation rendered as a full-screen, animated canvas. A static, blue gradient fill is applied based on the texture coordinate’s y-position, creating a uniform water-like surface. The piece uses the WebGL API directly via JavaScript, compiling custom vertex and fragment shaders to control geometry and color. It draws a single quad as a triangle strip and continuously re-renders it via `requestAnimationFrame`, though the color does not change over time.

Maiden Webgl Work

This WebGL example demonstrates real-time interactive 2D shape manipulation, showing a rectangle that users can translate, rotate, and scale through a dat.GUI control panel. The code builds a custom vertex and fragment shader pair that handles position transformation, converting pixel coordinates to clip space, while WebGL renders the colored rectangle on a canvas. It references WebGL Fundamentals' scaling lesson and uses the webgl-utils helper library to compile shaders, with all geometry defined as raw vertex data in a buffer.

shader gear

A real-time shader playground renders a series of WebGL fragment shaders as animated, full-screen visuals. The examples include smoothstep line plotting, mouse-interactive RGB gradients, distance-field circles, rotating polygon shapes with animated sides, and color-mixing loops—all driven by the uniform u_time. Shown side by side, they demonstrate how different GLSL functions shape geometry, color, and motion.

Cubehelix Interpolation II

A single-row canvas at 960 by 1 pixels renders a continuous horizontal color gradient, testing how interpolation behaves in Cubehelix color space. The code uses D3’s color module to compute the transition between two endpoint colors, drawing each column to the canvas with the `fillRect` method. This demonstrates how the Cubehelix model’s hue, saturation, and lightness axes produce a smooth, perceptually balanced ramp.
