Add lightmap demo #471

iche033 · 2020-12-02T20:59:18Z

depends on:

~~Add lightmap to 1.7 spec and PBR material DOM sdformat#429~~ released in 10.1.0
~~Add support for lightmaps in ogre2 gz-rendering#182~~
~~Add Lightmap to material gz-common#132~~ released in 3.9.0
~~Fix light map URI in materials gz-fuel-tools#146~~ released in 5.1.1

This PR demo's the new lightmap feature added in ign-rendering. It reads a new lightmap parameter from SDF and creates a material with lightmap using the new ign-rendering APIs.

One caveat is in the sdf-to-msgs conversion functions. I didn't add a lightmap field to the material.proto file in ign-msgs as that breaks ABI. So it's temporarily stored to the header. We can consider bumping ign-msgs if this is too much of a hack.

An indoor environment model has been uploaded onto Fuel. To run the demo:

ign gazebo -v 4 lightmap.sdf

I'm not sure exactly where the problem lies, but I get this (followed by maybe a dozen similar errors) when running it:

[GUI] [Err] [SystemPaths.cc:450] File [/home/osrf/.ignition/fuel/fuel.ignitionrobotics.org/openrobotics/models/indoor_lightmap/1/meshes/indoor_lightmap.dae] resolved to path [/home/osrf/.ignition/fuel/fuel.ignitionrobotics.org/openrobotics/models/indoor_lightmap/1/meshes/indoor_lightmap.dae] but the path does not exist

The files are actually found in

/home/mquigley/.ignition/fuel/fuel.ignitionrobotics.org/OpenRobotics/models/Indoor Lightmap/1

so it seems the username is incorrect as well as the caplitalization/space-vs-underscore of the generated filename

oops, I've fixed the paths in model.sdf and have updated the model on Fuel

I think you also need to add light_map to ign-fuel-tools here:

https://github.com/ignitionrobotics/ign-fuel-tools/blob/ef6c20d604fd744d709d1fb7a7e8bbf7a58e5a80/src/LocalCache.cc#L643-L658

Otherwise it's not getting converted to the URL, i.e.

                    <pbr>
                        <metal>
                            <albedo_map>https://fuel.ignitionrobotics.org/1.0/OpenRobotics/models/Indoor Lightmap/1/files/materials/textures/Wall_Albedo.png</albedo_map>

                        </metal>
                    </pbr>

And results in these errors:

Can we ticket an issue for this?

ticketed gazebosim/gz-msgs#109

This was addressed on gazebosim/gz-msgs#111. We could wait until ign-gazebo5 is updated to use ign-msgs7 and use the new field here (gazebo-tooling/release-tools#362)

sure sounds good

I think this is unblocked now

Is the light_map.png file suppose to exist?

No, I think this is just testing that the conversion between SDF and messages works fine, without worrying about resolving the file.
