Add Lens Flare System #1933

jasmeet0915 · 2023-03-16T16:14:56Z

🎉 New feature

Closes #1909

Summary

Added Lens Flare System that adds Lens Flare Render Pass to the camera and allows users to enable lens flare in camera images. The lens flares can be configured using <scale>, <color>, and <occlusion_steps> tags in the SDF.
Added an example camera_lens_flare.sdf file for testing which contains 2 cameras(wide angle and normal) with different configurations for the lens flare (one default and other custom).

Test it

Make sure to use the gz-sim8 and compatible versions of other packages especially gz-rendering8 since it contains the Lens Flare Pass.
Launch the examples/worlds/camera_lens_flare.sdf file from the gz-sim repo using:

gz sim camera_lens_flare.sdf

nice, this works well for me! I left a few comments, mostly coding style changes.

remove a couple of extra lines here

+              <type>gnomonical</type>


hmm just noticed that there could an issue with the gnomonical type on certain graphics drivers, e.g. on mesa + llvmpipe the camera does not render properly but works fine on Nvidia drivers. Something to be investigated later. In the mean time, can you change this to equidistant? and maybe make the the horizontal_fov larger to make it obvious it's a wide angle camera, e.g. 3.14159

+    // call function that connects to post render event
+    // using a separate function because unique_ptr (this->dataPtr)
+    // is not supported as a argument of std::bind
+    this->dataPtr->ConnectToPostRender();


you should be able to do:

this->dataPtr->postRenderConn = this->dataPtr->eventMgr->Connect<events::PostRender>( std::bind(&LensFlarePrivate::OnPostRender, this->dataPtr.get()));

to be consistent with gazebo coding style, can you change indentation from 4 spaces to 2 spaces in this file?

I think you missed this one. Can you update the indentation?
