						Optimize three vertices of a single triangle
						Optimize six vertices of two triangles (note that one vertex is occluded but still we optimized it correctly).
						Optimize three vertices of a triangle where one of the vertices is far behind the camera
						Optimize four vertices of the blocker casting shadow
						Optimize translation of light source
						Optimize 4 vertices of a shadow receiver
						Optimize camera position
						Optimize 4 vertices of plane with texture
						Optimize camera position, diffuse/specular reflectances, and roughness of the teapot.
						Optimize 4 vertices of the occluder. The floor is highly glossy.
						Optimize the translation of the plane behind camera with SIGGRAPH logo texture. The teapot is highly glossy. We disable caustics light paths (LS*DE) for this scene for managable rendering time.
						Optimize translation and rotation of the bunny. For this scene we used a Gaussian pyramid L2 loss.
						Optimize camera position and direction. For this scene we used a Gaussian pyramid L2 loss.
