Learn more about creating new 3D feature classes To create a new multipatch feature class, simply choose Multipatch Features from the Type drop-down menu when defining the feature class's geometry. How do I create a multipatch feature class? You can use the Is Closed geoprocessing tool to verify that a multipatch is properly closed.Įxamples of multipatch features include textured buildings, lamp posts, trees, subsurface geologic formations, underground structures, or certain types of analytic surfaces. The patches must not intersect each other, and there must be no gaps or empty spaces in the shell. The patches it is composed of must all have the same counterclockwise orientation of their coordinates and participate in defining the shell of the volume. The feature must represent one distinct volume. ![]() For a multipatch to be considered closed, it must be constructed in the correct fashion. Closed multipatches may be used in additional analysis tools, such as Union 3D and Intersect 3D. Some multipatch features are considered closed, meaning they properly define a volume. While it is possible to model the base z-value of a multipatch using a numeric feature attribute, this option may not support all the same analysis and interaction options that are available when using embedded z-values. Primitive geometry types: POINTS, LINES, LINE_LOOP, and LINE_STRIP.All multipatches store z-values as part of the coordinates used to construct patches.All glTF extensions except MSFT_lod and KHR_Materials_pbrSpecularGlossiness, as noted above.The glTF document scene must be set to a specific scene, or there must be exactly one scene in the glTF document.The features that are not currently supported from the glTF specification are as follows: Unsupported features from the glTF specification Specular Glossiness defined by the KHR_Materials_pbrSpecularGlossiness extension.Morph target animation (position, normal, uv, tangent, color).Of specifying attributes using buffers, bufferViews, and accessors, TRIANGLE, TRIANGLE_STRIP, and TRIANGLE_FAN. If itĪppears elsewhere, all occurrences of MSFT_lod are ignored. MSFT_lod can only appear in the first node of a scene. ![]() Supported, but only node-based LODs, not material-based LODs. ![]() Full-node hierarchies, including node transformations and mesh.The currently supported features from the glTF specification are as follows: Supported features from the glTF specification This gives models a distinctive sense of realism that can't be achieved with only flat color. Such as shininess, roughness, or metalness. GlTF markers can include material properties This scalability means that when the marker is in the distance in a scene, it draws with less complexity than when it is drawn in the foreground, nearer to the viewer. Multiple levels of detail (LODs) to manage their display in an efficient and sensible way across a range of view distances. glb) files are binary versions of a glTF file that also include embedded assets such as textures. glTF file) is an industry-standard interchange format for the transport ofģD models.
