VTK Examples - New Physically Based Rendering examples

Announcements
1

I have added fourteen PBR examples to vtk-examples.

They are:

C++ Python Description
PBR Anisotropy PBR Anisotropy Render spheres with different anisotropy values.
PBR_Clear_Coat PBR_Clear_Coat Render a cube with custom texture mapping and a coat normal texture.
PBR Edge Tint PBR Edge Tint Render spheres with different edge colors using a skybox as image based lighting.
PBR HDR Environment PBR HDR Environment Renders spheres with different materials using a skybox as image based lighting.
PBR Mapping PBR Mapping Render a cube with custom texture mapping.
PBR Materials PBR Materials Renders spheres with different materials using a skybox as image based lighting.
PBR Materials Coat PBR Materials Coat Render spheres with different coat materials using a skybox as image based lighting.

These examples are derived from the various VTK PBR tests. I hope that they will encourage those considering Physically Based Rendering to experiment. As the results are oftern really beautiful.

They all use a common JSON file which should make things easy as PBR often requires lots of files.

Wow, just wow! Wonderful additions

Amazing! Thank you, Andrew!

You can now view tthe PBR examples as a group in:

You can also see the relevant pictures there.

I have now updated the original three examples PBR_Skybox, PBR_Skybox_Texturing and PBR_Skybox_Anisotropy. They have a new command line parameter -t that activates tone mapping. When this is activated, a slider for exposure will appear.

For all the PBR examples:

  • The description of the JSON file is here: PBR JSON file format.
  • The function reading the JSON parameter file is the same.
  • The function displaying the parameters is the same.
  • Functions for the reading of cube maps and equirectangular files are also the same .
