volumetric-model-meshes-1.0.0-surfaces-vmm_category_boundary_surface

volumetric-model-meshes (v1.0.0)​

A contact between two categories, or between one category and unassigned space inside the model extent. Where a category meets the boundary of the extent, the surface is a model boundary surface carrying that category instead.

PropertyTypeDescriptionFlags
nameStringName of the object.⬆️ ✅
descriptionStringOptional field for adding additional description to uniquely identify this object.⬆️
qualitymesh-qualityMesh quality.⬆️
partsArray[reversible-index]A list of parts and whether they are reversed.⬆️ ✅
material_keyStringKey of the entry in 'materials' that describes how this surface should be presented. A surface carries a single material, so a surface that separates two differently presented regions takes its appearance from that one entry.⬆️
surface_typeStringIdentifies this surface as a contact between categories.✅
categoriesArray[Integer]Keys into 'category_lookup' identifying the categories the surface separates, ordered so that the triangle normals point from 'categories[0]' towards 'categories[1]'. Two entries for a contact between two categories, where the first is the category behind the surface and the second is the category in front of it. One entry for a category against unassigned space inside the model extent, where the normals point away from that category. The front of a triangle is the side from which its three vertices appear in counter-clockwise order, which is the side its normal points towards; a part referenced with 'reversed' set to true has its front and back swapped.✅
