Render Options
Software version : 10.0.148 (Jun 17 2013) * Render Options : Render used the 'raytrace' hider Image resolution: 640 x 480 Pixel oversampling: 2 x 2 Total number of displays (AOVs) : 2 Shared instances (for massive instancing) : on
The information included in these statistics give some general information about render settings that can affect performance. The first line is always the software version so it is easy to see what 3Delight version was used to render the frame.
Statistic | Description |
---|---|
Render used the 'raytrace' hider | This says wheter REYES or ray tracing was used to render the images. |
Image resolution: 640x480 | Image resolution. |
Pixel oversampling: 2 x 2 | The oversampling used for this image. |
Total number of displays (AOVs) | Says how many AOVs are output in the current render. |
Shared instances (for massive instancing) : on | This says if 3Delight is using a special optimization to render large amounts of object instances. |
System
* System : Total physical memory : 8.6GB CPU Physical cores count: 2, logical cores count: 2 Render threads started by user : 2 Network reads : 1.48 Mb total. Transfer rate: 137.6 Kb/s Network writes : 1.48 Mb total. Transfer rate: 137.7 Kb/s Load average: 1.2 0.9 1.1 Time to first pixel : 1 seconds.
This statistics block gives information about the system that was used to render.
Statistic | Description |
---|---|
Total physical memory : 8.6GB | Gives the total amount of memory installed on the system |
CPU Physical cores count: 2, logical cores count: 2 | Gives physical and logical core count. Logical core count includes "hyperthreading" processors. |
Render threads started by user : 2 | Says how many threads have been started by the user |
Network reads : 1.48 Mb total. Transfer rate: 137.6 Kb/s | This interesting statistics gives the total amount of data that has been read from the network while rendering the image. Note that this count all the network data and not only the data that is used for rendering. This statistic is helpful to debug network performance problems. |
Network writes : 1.48 Mb total. Transfer rate: 137.7 Kb/s | Similar to the statistic above but for network writes. |
Load average: 1.2 0.9 1.1 | Load average is a gauge of how many processes are on average, concurrently demanding CPU attention. The three numbers are averages for 1, 5 and 15 minutes. Very detailed description of load averages can be obtained on Linux manpages of uptime. A good technical overview can be found here and good vulgarization can be found here. |
Time to first pixel : 1 seconds. | This somewhat misplaced statistic shows the time it took before the first pixel has been sent to the user. It is always a very important goal in 3Delight to minimize this time. |
