Testfile

• check out the functionality with this Grasshopper Definition

Export

• exported gltf

Motivation

• I recently saw that shapediver is now suggesting to use the Rhino8 native gltf export, so I wrote the script to leverage that.

Component Descriptions

GLTF-Export

• This Component implements two ways to output the gltfs

1. It outputs the entire scene
2. It outputs only the grasshopper geometry

GLTF-Options (Optional) [v1.1.0+]

• Here you can edit all the export settings in one place

1. Draco Compression
2. Formatting
3. Mesh Settings

Adding Materials

• A simple video each; showing:
  • Export GLTF With Custom Material - how to use this in general
  • Export GLTF With Downloaded Material - how to use this with a downloaded material
• Find out more about how to create Physically Based Materials in the Rhino Documentation

gltf-export's Issues

Debugging with Visual Studio

The Plugin doesn't load for debugging:

• Issue to reproduce:
  • GrasshopperDeveloperOptions > Add Assembly > .\GH-Helper\Web_Exporter\GLTF-Export\bin\Debug\net7.0
  • Start debug Session from within Visual Studio
  • hit space bar and type Gltf Exporter or gltfExp
  • the component doesn't show up
• Workaround:
  • drag and drop the latest .gha from bin onto canvas during debug session
• Possible Causes:
  • the postbuilt event in the .\Web_Exporter.csproj under Target
    (added because according to MS the <TargetExt>.gha</TargetExt> isn't supported in .net7 anymore) is:
    • renaming the .dll after the debugger starts rhino/grasshopper
    • causing some other issue
  • my machine has issues with loading Assemblies through GrasshopperDeveloperOptions
  • some other Rhino8 or .net7 related problem

Casting to ArchivableDictionary

AddGenericParameter does not work for Rhino.Collections.ArchivableDictionary, also GH_ParamAccess.itemseems to create an issue for this.
