Render OBJ files

[harora]

Hi

I'm looking to evaluate the work using image-based metrics. Can you share mistsuba2 scene xml file for rendering mesh objects?

Hi @harora,

Mitsuba 2 was only used to compute surface normal consistency. Therefore, it's just a regular Mitsuba XML file with the mesh centered at zero with the aov integrator for the surface normals:

<integrator type="aov">
    <string name="aovs" value="sh_normal:sh_normal"/>
    <integrator type="direct" name="my_image"/>
</integrator>

Last time I checked, Mitsuba 2 did not have two-sided normals for AOVs so faces with flipped/inward normals will appear black. You can either hack the AOV integrator and recompile or make a new integrator that uses the absolute shading normals.

Best,
Joey

The problem is i'm getting different result for same field-of-view(fov) parameter which is why i could know if there's any other parameter i need to set to get exact same results. Can you share 'sensor' settings in xml?
