Built on OpenVDB, the system efficiently stores sparse and dense voxel data using tiles and active status flags. Users can now perform fluid simulations, SDF modeling, and scientific data visualization through nodes that handle field-to-grid conversion, grid sampling, boolean operations, and vector calculus. The implementation includes grid transforms for mapping index-space to object-space, integration with the field system for procedural evaluation, and specialized SDF filters for smooth boolean operations. ## Full article daily.dev links to this article rather than hosting it.
