Скачать или смотреть [V0034] [Mb3Ak] Grid origin or face plane on object

My editor has a bunch of plugins that are independent of the semantics of the underlying world I am editing. Almost all of the plugins used in this version with brushes and soon also curved patch meshes came from the Minecraft version of the editor and didn't have to be altered to work in this new scenario.
The grid is a particularly interesting plugin in that regard because even though it should function the same in all variants of the editor, it also needs to interact with the semantics of the underlying world. Here, I've uncoupled the raytracing for positioning the grid from the rest of the plugin. This video shows the two new functions of positioning the grid origin on an object and positioning the best matching plane of the grid on an object (comparing the normals). If I was still working on the Minecraft variant of the editor, I could now pretty quickly let the grid interact with the Minecraft world in just the same way.
