Walkthroughs

Complete step-by-step examples and how-tos. Each one is run end to end, with the real output of each tool quoted, including where the result is surprising.

• Coordinate orientation demo. One monkey mesh from Blender through the Sample Viewer to Gazebo and RViz, showing the coordinate convention at each step and the rotation each consumer needs.

• Exporting from Blender. The export defaults that produce most of the defects we see, and what to do instead.

• Checking a delivery. The four conformance questions, what answers each, and how to read gltf-check output.

• BlueBoat walkthrough. The workflow applied to the BlueBoat chassis and propellers, step by step, as the pilot runs. In progress.

  • Texture format is decided by the source image
  • Transparency is per material, not per pixel
  • Turn on Apply Modifiers
