Halfspace是一个实验性固体建模集成开发环境，采用距离场技术处理隐式曲面，旨在解决传统CSG方法的局限1。该项目以Fidget几何内核为基础1，开发者从2025年4月起开始进行开发1。
项目采用Rust、egui、wgpu和Rhai等技术栈1，实现了完整的CPU到GPU渲染管道迁移，提升了Web平台的性能表现1。Halfspace为用户提供了图形用户界面，支持实时光栅化和网格导出功能，允许将模型以图像或三角网格格式进行导出1。该项目的开发也驱动了Fidget内核在GPU渲染方面的重大改进1。项目采用MPLv2开源许可证发布1。
Halfspace is an experimental integrated development environment for solid modeling that leverages distance fields to create three-dimensional objects 1. Development of the project began in April 2025 1, and it is built upon the Fidget geometry kernel, which provides the computational foundation for the modeling operations 1.
The IDE offers a graphical user interface designed to enable real-time rasterization and mesh export capabilities 1. By positioning implicit surface distance fields at the center of its design approach, Halfspace addresses limitations inherent in traditional constructive solid geometry methods 1. The technical implementation utilizes a cross-platform technology stack comprising Rust, egui, wgpu, and Rhai 1. A significant achievement of the project has been the migration of the complete rendering pipeline from CPU to GPU processing, substantially improving performance on web platforms 1.
