melo

melo is mesh loader for OBJ, glTF2 and PLY, also includes a Cinder based mesh viewer on Windows and macOS.

Features

TODO

  • Implement skinning animation
  • Implement morph animation
  • Support Linux / Android / iOS
  • Support Sketchfab download API
  • FrameGraph

To build samples/MeshViewer, you need:

The folder structure should appear like this:

  1. Cinder/
  2.     blocks/
  3.         Cinder-VNM/
  4.         melo/
  5.             samples/MeshViewer/vc2015/MeshViewer.sln
  6.             assets/
  7.                 Cube/
  8.                     Cube.gltf
  9.                 cerberus/
  10.                     Cerberus.obj
  11.                 Awesome-gltf-files/
  12.                     scene.gltf
  13.                     scene.bin
  14.                 Symbolic-links-are-also-supported
  15.     include/
