decotengu is a dive decompression library to experiment with various implementations of the Buhlmann decompression model with Eric Baker’s gradient factors. The results of decotengu calculations are decompression stops and tissue saturation information. Third party applications can use those results for data analysis purposes or dive planning functionality.
Release Notes: This release adds NDL dive detection before dive ascent start. The 'dt-plot' script is reimplemented to use R core plotting functions (ggplot2 is no longer required, which gives a major performance gain), and legend plots generated by the script have been added. The documentation has been updated with a section about comparing dive decompression data with the 'dt-plot' script. This is the first beta release.
Release Notes: Trimix support has been implemented. Travel gas mixes can be added to the gas mix list. A Buhlmann equation description has been added to the documentation.
Release Notes: All calculations are now performed using pressure instead of depth. This release implements a decompression model validator to check whether the first decompression stop is at an ascent ceiling.
Release Notes: Gas mix switching is now performed in more controlled manner. The API has changed, and conveyor functionality removed from the decompression engine class. (Instead, conveyor objects can be used to expand dive profile dive steps by replacing the Engine.calculate method). The documentation has been updated to contain a more detailed Schreiner equation description.
Release Notes: This is the initial release.
