![]() ![]() I can load the SCNGeometry into an MDLMesh, create another one based on that using initMeshBySubdividingMesh and then generate normals and then turn it into SCNGeometry again. I want to utilize the normal generation and subdivision and file export options etc from ModelIO. I currently use geometryWithSources to generate a SCNGeometry object and assign that to an SCNNode. Specifically I have a half-edge datastructure that is updated frequently (though not every frame). The bold part is what I aim to do, create meshes from my own vertex data. You can also create meshes from your own vertex data or create parametric meshes" This way, a user can easily see which environments affect the model.As written in the docs for MDLMesh: "Typically, you obtain meshes by traversing the object hierarchy of a MDLAsset object, but Expose geoprocessing environments you set in the model as model variables.Use the ModelBuilder > View > Auto layout command, or move the elements manually to make a model straightforward to follow. Make the model layout (how elements are arranged) readable.Rename variables and tools so they have context within the model.In addition to the standard documentation you write for your model tool, follow these recommendations to make your model diagrams straightforward to read and follow: Right-click the model tool in its toolbox, select View Metadata, and click the Description > Edit button in the tab. You write help documentation for a tool by modifying its metadata. Learn more about model properties Document the toolĪn important part of creating a good model tool is writing help documentation that will allow others to understand and use your tool efficiently. You can change this and other model tool properties, such as the order of parameter display, by right-clicking the model tool in a toolbox and selecting Properties. When you open a model tool in the Geoprocessing pane, the model tool's label is displayed at the top of the pane. ![]() Alternatively, click ModelBuilder > Insert > Variable, choose a data type, click OK, and connect the new variable to a tool or use it for inline variable substitution. To add additional model variables so you can set them as model parameters, right-click any tool, select Create Variable, then select the desired tool parameter or environment. Model variables are automatically created for the input and output datasets of a tool, but not for any other tool parameters. You may need to expose additional tool parameters as model variables to set your model parameters. For example, an intermediate output feature class should use a path such as %scratchgdb%\intermediateBuffers. If you plan to share the model, or use the model on a different system, all intermediate data should use an in_memory output path, or use inline variable substitution to a workspace environment path to ensure that the output directory exists for intermediate data that is created. You can use the in_memory workspace as a location for intermediate data in your model. When a model tool is run from the Geoprocessing pane, all intermediate output data is automatically deleted when the tool completes, except datasets from model output parameters. Some of the data created is of no use after the model is run since it was only created to connect to another process that creates new output. When you run a model, output data is created for each process in the model (unless the process only modifies the input). Learn more about model parameters Intermediate data Once the model parameters have been created, you can run the model as a geoprocessing tool, supplying different values and datasets for its parameters. To display parameters on the tool dialog box, and to add output datasets to a map, you must set model parameters within your model. No output datasets will be added to a map. At this point, you may run the tool, and the data and settings hard-coded in the model will be used. If you built your model without setting any model parameters, when you open the model tool in the Geoprocessing pane, the tool dialog box will display no parameters. Learn more about building geoprocessing models.Build and save a model within ModelBuilder.To create a model tool, do the following: You can configure a model tool so you can process different datasets with different settings than those specified inside the model, without actually modifying the model variables in ModelBuilder. Model tools can be run like any other geoprocessing tool from the Geoprocessing pane and used in other models and Python scripts. A geoprocessing model is saved as a model tool in a toolbox. ![]()
