| # glTF file writing | |
| - Sets a blue-gray background, creates a wavelet, shows it as a surface colored by RTData, fits the camera, and exports the view to a glTF file (`ExportedGLTF.gltf`). | |
| - Reads the exported glTF back, displays it as a surface, and verifies exported texture coordinates by coloring with the magnitude of TEXCOORD_0 using the cool-to-warm transfer function, with axes hidden and camera reset. | |
| - Saves a screenshot of the reloaded glTF rendering to `export-gltf-screenshot.png`. | |
