Spotted Balloon Bursts
WebGL Shader with GLSL
This WebGL shader causes a spotted balloon texture to expand in the center then burst at the end.
The Kindle book, Simple Shaders: Learn WebGL Book 4, provides detailed implementation for this example.
Swipe Over the Balloon!
The GLSL vertex shader distorts the mesh. Center vertices move toward the viewport. The spotted pattern accentuates the effect.
This example loads a lightweight square mesh with just four quadrants. Consider adding more quadrants for smoother edges on the balloon.
