API Reference

Attribute Type Default
base-image URL of the base image that is initially visible. string ""
reveal-image URL of the image to reveal through the fluid mask. string ""
dissipation How quickly the fluid density dissipates over time (lower = faster fade). number 0.96
pointer-size Size of the cursor's influence on the fluid simulation. number 0.005
velocity-dissipation How quickly fluid velocity dissipates (affects swirl duration). number 0.96
pressure-iterations Number of pressure solver iterations (higher = more accurate but slower). number 10
blend-softness Softness of the edge between the two images in the blend zone. number 0.22
