I was fiddling around in the code base as I was looking into adding a new type of viewer as the SDL version always crashes for me (OSX 11.6.5, multiple versions of SDL)*.
What I found was that no matter what the size of the camera statement in the XML file, the output image size is always 1024, 512 (the default). On top of that, there seems to be a bug in the reader with the scene_world_volume.xml. The reader reads the initial camera statement, hits the transform with the nested camera type, and clears all the information from the size read in the first statement.
- I’ve added the ability to use the stand-alone version with the tev HDR viewer (https://github.com/Tom94/tev) similar to what pbrt-v4 does.
