Week 2 - Improving Fetcher and Exporting glTF ============================================= .. post:: June 29 2022 :author: Shivam Anand :tags: google :category: gsoc What did you do this week? -------------------------- This week I worked primarily on the glTF fetcher and exporting scenes to a glTF file. I added tests and docstrings for all functions. I modified the ``fetch_gltf`` function to return the downloaded files. As we planned, the PR for the glTF fetcher was merged this week. I fixed the color issue of the glTF exporter by manually appending the color data from the actor to the ``polydata``. But there's another issue raised while using actors from ``vtkSource``. The ``utils.get_polydata_triangles(polydata)`` method only works with primitives and it raises an error when used with ``vtkSource`` actors. Textures and Cameras can now be added to the glTF file. However, it supports baseTexture only. I'll be working on materials support later on. What is coming up next week? ---------------------------- * Saving all models download link (from the Khronos glTF-Samples-Models repository) to a JSON file, create a separate branch and add the download script. * Add tests and docstring for PR `#600 `_. * Create a PR for glTF exporter. Did you get stuck anywhere? --------------------------- * I managed to fix colors in polydata by adding them manually, but it raised another issue with indices (triangles) of the actor weren't of the correct shape. We decided to take a look at it later. * Due to Github's API limit, it raised an error due to limits exceeding. We decided to save a JSON file with all model names and their download links. Then use that to download the model.
