In this tutorial, we develop a procedural visual system based on sine wave generation to produce a dynamic motion effect. The process begins with the construction of a base 3D geometry that serves as a spatial reference for wave deformation. Using parametric sine functions, we define amplitude, frequency, and phase offset to control oscillatory behavior over time. These waveforms are then applied to the geometry through instancing techniques, allowing efficient duplication and transformation of primitives while maintaining low computational overhead.
Once the structural motion system is established, we implement a shading pipeline that includes color modulation and material definition. Color is introduced through controlled parameter mapping, followed by the creation of a custom material to manage surface response, reflectivity, and light interaction. A mirror effect is integrated to enhance spatial perception and symmetry. Additional temporal processing is achieved by incorporating a feedback loop and a slit-scan component, enabling frame accumulation and time-based displacement for more complex motion trails.
In the final stage, post-processing adjustments refine the overall visual output. HSV adjustment and level correction are applied to balance chromatic intensity and contrast range. To increase textural richness, a controlled grain layer is added, introducing high-frequency detail. Finally, a LumaBlur operator is implemented to soften luminance transitions selectively, improving depth perception and blending dynamic elements into a cohesive visual composition.
