| 1 | | This ProtocolZero query is much like [[rf]], except that it is designed for large-scale image acquisition. Normal [[rf]] returns only one sample per command, and thus a user attempting to get a large number of samples by sending many queries to it at a variety of angles suffers poor performance and risks overflowing the Quagent's command queue.

Normal [[rf]] returns only one sample per command, and thus a user attempting to get a large number of samples by sending many queries to it at a variety of angles suffers poor performance and risks overflowing the Quagent's command queue. [[rb|rb]] improves upon rf by allowing the user to specify a region of samples with only a single command. High-resolution data can take some time to write: the game will appear to hang while it does. On machine "e33" in the lab, this command can acquire about 250,000 samples per second (so, for example, it takes 2 seconds to get a 720 by 720 area). |

| | 10 | * [[rb|rb]] returns a number of samples generated by accumulating sample_deltas. Increasing YAW makes the bot turn left, so for positive sample_delta_yaw, subsequent samples are more to the left. This is not the standard image coordinate system where increasing samples in the X direction are to the right. In other words, the "image" would be flipped horizontally from what the bot would actually "see". |
| | 11 | * [[rb|rb]] generates the image by a process that is suggestive of a fisheye lens, not a linear projection. For example, it is possible to have a raster that contains the results of rays looking directly ahead and behind, an impossible perspective for linear projections. Wall seams will appear curved, etc. |
