WebGL shaders fill an octagon with a cloud texture. The vertex shader determines color location. The fragment shader prepares color for display.

The animated octagon vertex shader processes circle coordinates from the current vertex coordinates. The Animated Spotlight fragment shader processes circle coordinates from the current texture coordinates. Compare the difference in granularity between the two shaders. The fragment shader processes more often with more detail.
