Profiling Renderer Options
Keyword	Type	Units


`time_to_first_pixel`	real	seconds	Time it take for the first pixel to appear.
Profiling
`timings`	table	time	Time taken to produce the image, for a wide range of timed categories.
`memory_profile`	table	Mb	Memory used to produce the image, for a wide range of categories.

Netword Cache
`cache_size`	real	GB	Total cache size.
`used_size`	real	GB	Amount of space already used.
`number_of_copied_files`	integer		Total number of files copied to that cache during this rendering session
`number_of_failed_copies`	integer		Copies that failed for system reasons (space, permissions, etc ...)
`number_of_copies_avoided`	integer		Copies avoided because files already in cache
`number_of_rejected_files`	integer		Files not copied because cache is full
`sizeof*number_dataof_alreadycopies_inavoided_cachekb,`	integer	Kb		Same as `number_of_copies_avoided` but in Kb.
`sizeof_data_not_cached`	integer	Kb		Data not cached due to lack of space.
`sizeof_data_cachedcopied`	integer	Kb	Total amount of data that has been copied to the cache during the rendering sessions.
Maps
`number_of_maps`	integer		Total number of maps (textures, shadow maps, deep shadow maps, etc ...) managed.
`number_of_texture_maps`	integer
`number_of_shadow_maps`	integer
`number_of_deep_shadow_maps`	integer
`number_of_invalid_maps`	integer
`number_of_file_open_operations`	integer		Total number of file open operations performed during a rendering session. Should be relatively low thanks to caching. Could be high on systems configured with not enough file descriptors.
`*number_of_map_requests`	integer		Total number of maps requested
`texture_access_statistics`	table

Scene
`number_of_objects`	integer		Total number of high level objects passed to renderer.
`number_of_attributes`	integer		Number of RenderMan attributes needed to describe the scene.
`number_of_transforms`	integer		Number of transforms in the scene.
`primitive_compression_ratio`	real		While rendering, 3Delight uses a compression algorithm for geometric primitives residing in memory. This statistic indicates the compression ratio.
Reyes
`distributionnumber_of_micropolygon_areamps`	histograminteger		An histogram representing the distribution of the area of micro-polygons. Distributions skewed towards lower values mean slower renders.
`distribution_of_fragment_lists`	histogram		Depth complexity.
Ray Tracer
Total number of micro polygons generated to produce the image.
`average_mps_per_grid`	integer		Average number of micro polygons per grid.
`grids_projected`	integer
`grids_shaded`	integer
`grids_displaced`	integer	`distribution_of_ray_depth`	histogram
`distributionnumber_of_shading_groupsprimitives`	histograminteger		Represents the distribution of shading group sizes. Histograms skewed to lower values represent less efficient shading.	Total number of low-level primitives.
`numberdistribution_of_rayrejected_typesprimitives`	table		A table describing how many rays were traced, per type (specular, diffuse, transmission, ...). Note that this is a table, not an histogram.
`distribution_of_shader_calls`	table		Describes how many shader calls were performed, per ray type.
Point Based Subsurface Scattering
Total number of low-level primitives that have been efficiently rejected because they were are not seen in the image.
`number_of_non_empty_buckets`	integer
`average_items_per_bucket`	integer		Average number of items (primitive, grid, particle, etc ...) in a bucket.
`maximum_items_per_bucket`	integer		Maximum items found in a single bucket.
`distribution_of_micropolygon_areadistribution_of_lookup_depth`	histogram		An histogram representing the lookup depth in the hierarchical structure used to store the point-based scene representation. Histograms skewed to distribution of the area of micro-polygons. Distributions skewed towards lower values mean faster renders. A technical statistic that is not really telling for an artistslower renders.
`distribution_of_fragment_lists`	histogram		Depth complexity.





`*curves_grouping_efficiency`	real
Ray Tracer
`distribution_of_ray_depth`	histogram
`distribution_of_shading_groups`	histogram		Represents the distribution of shading group sizes. Histograms skewed to lower values represent less efficient shading.
`distribution_of_ray_types`	table		A table describing how many rays were traced, per type (specular, diffuse, transmission, ...). Note that this is a table, not an histogram.
`distribution_of_shader_calls`	table		Describes how many shader calls were performed, per ray type.
Point Based Subsurface Scattering
`distribution_of_lookup_depth`	histogram		An histogram representing the lookup depth in the hierarchical structure used to store the point-based scene representation. Histograms skewed to lower values mean faster renders. A technical statistic that is not really telling for an artist.

`motion_density`	real
`motion_segments`	integer
`maximum_node_depth`	integer		Maximum leaf node depth in the space partitioner.
`number_of_rays`	integer		Total number of rays that went through the space partitioner.
