Unity ECS-Style Voxelization

Installation

• Clone Unity Official ECS Samples.
• Clone this repository to Samples/Assets folder.

Parameters overview

The following are adjustable parameters in VoxelizationSystem.

• voxelSize Voxelization resolution. Small value leads to higher memory use.
• minDuration A lower bound of duration. Used for small-scale voxelization to delay the spawning process.
• maxMovingNumber Maximum allowed number of simultaneously moving voxels. Smaller value leads to longer duration and better frame rate.
• modelName The name of model to be loaded in Resources/ folder.
• bottomColor & topColor The color of bottom and top of voxelized model. The rest will be interpolated.
• volumetric Whether to perform volumetric voxelization (expansive).
• randomOrder Whether to randomize spawn order.
