Rendering equirectangular images from replica in HDR (.hdr or .exr) #988

❓ Questions and Help

Hello. Thanks for this amazing platform.

I have the following questions :　 1) How do I render hdr (.hdr, .exr not rgba) images from the replica dataset using habitat-sim? 2) How do I render equirectangular images?

Thank you

  1. See the example from Habitat-Lab about how to render equirect images from a cubemap.
  2. Pretty sure Magnum supports reading/writing HDR files, but I don't know if we actually support HDR rendering in Habtiat-Sim. @bigbike @mosra

@bigbike , @mosra . Hello, I hope you are well. Does habitat support writing HDR files? exr, or hdr. Specifically for the replica dataset as it comes with high dynamic range textures. Thank you

@mosra @bigbike I also want to know how to render HDR images. Looking forward to your help. Thank you!

Magnum does support writing HDR and EXR files but Habitat isn't ready for that right now -- it always renders to a 8-bit framebuffer. It would need to be updated (here, here and probably some other places as well) to add an option for 16-/32-bit float output next to 8-bit.

Thanks alot for your help and I have been able to render HDR images.
