A shader hook block that sets the color for each pixel in a filter shader. This hook can be used inside buildFilterShader() to control the output color for each pixel.
filterColor has the following properties:
texCoord: a two-component vector representing the texture coordinates (u, v).canvasSize: a two-component vector representing the canvas size in pixels (width, height).texelSize: a two-component vector representing the size of a single texel in texture space.canvasContent: a texture containing the sketch's contents before the filter is applied.
Call .set() on the hook with a vector with four components (red, green, blue, alpha) to update the final color.
This hook is available in:
