Create flash dump of mtd2 or mtd3 (Image A / Image B):
dd if=/dev/mtd2 of=/tmp/mtd2
Download flash dump from SFP (e. g. using TFTP).
Update: I created jq-zsh-plugin that does this.
One of my favourite tools of my trade is jq. It essentially enables you to process json streams with the same power that sed, awk and grep provide you with for editing line-based formats (csv, tsv, etc.).
Another one of my favourite tools is fzf.

Default stack trace depth is 5. This can be changed by passing -d or --depth. | |

So, many places will give you clues how to get linear depth from the OpenGL depth buffer, or visualise it, or other things. This, however, is what I believe to be the definitive answer:
This link http://www.songho.ca/opengl/gl_projectionmatrix.html gives a good run-down of the projection matrix, and the link between eye-space Z (z_e
below) and normalised device coordinates (NDC) Z (z_n
below). From there, we have
A = -(zFar + zNear) / (zFar - zNear);
B = -2zFarzNear / (zFar - zNear);
