This package allows you to create heat maps using particles in Unity. It's designed to be easy to use, with a simple and intuitive interface. The heat map effects are based on HDRP production, but may require shader modifications for other rendering pipelines. The package includes a sample scenario to help you get started and understand the principles of modifying the effects.
The effect works by mapping coordinate points to the nearest sampling point, accumulating weights based on the sampling point and influence range, and then using a particle system to convert the calculated matrix to the corresponding position. Automatic weight calculation is available, or you can set custom weight values to achieve different effects. The number of particles must be greater than the number of points affected by sampling.
