2014-02-12Use "rint()" instead of rounding manually with "+ 0.5"Gravatar Linus Torvalds
rint() is "round to nearest integer", and does a better job than +0.5 (followed by the implicit truncation inherent in integer casting). We already used 'rint()' for values that could be negative (where +0.5 is actively wrong), let's just make it consistent. Of course, as is usual for the messy C math functions, it depends on the current rounding mode. But the default round-to-nearest is what we want and use, and the functions that explicitly always round to nearest aren't standard enough to worry about.

2014-02-11Fix ATM-vs-bar confusionGravatar Linus Torvalds
SAC should be calculated in relationship to surface pressure, not "1 bar". I also realize that we have a few other cases where we do the same mistake: the partial pressure calculations do things like po2 = o2 / 1000.0 * depth_to_mbar(sample->depth.mm, dive); which is wrong as well - the partial pressure is also relative to standard atmospheric pressures.

2014-02-10Use 'struct membuffer' for profile info string generationGravatar Linus Torvalds
The profile info was generated using nasty string concatenation that the membuffers are much better at anyway. And membuffers don't need those arbitrarily sized fixed buffers (500 bytes? Why 500 bytes?). Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org> Signed-off-by: Dirk Hohndel <dirk@hohndel.org>

2014-02-05Created a method to check if calculations should take place.Gravatar Tomaz Canabrava
Created a method to check if calculations should take place taking into consideration what changed on the model. if the model changes *everything*, them, all calculations should be done, but if just some of the columns of the model are changed, only those columns should trigger an visual update on the items. In theory this patch looks right, but something is wrong ( calculations are not being made. ), so I'll commit this any how, and fix on the next commit.

2014-01-29Always calculate deco data, independent of preferencesGravatar Tomaz Canabrava
This is a better way since we can enable / disable the deco by changing the preferences later, and that will not need to recalculate everything just because a polygon was set to invisible. Signed-off-by: Tomaz Canabrava <tcanabrava@kde.org> Signed-off-by: Dirk Hohndel <dirk@hohndel.org>
2014-01-27Add settings awareness for the PP graphGravatar Tomaz Canabrava
This commit is rather big, and I forgot to cut it in pieces. The first part creates a new 'calculate_gas_information' that will not fill the profile_info->maxpp member ( that should be removed from it as soon as the new dialog is finished ). The reason for that is that all of the profile data will be calculated and the graph needs to update dynamically, so whenever the settings changes, I ask for the model which is the biggest graph and replot only the ones we need. The second part adds a new animation function 'animdelete' to fade-out and delete the item when it's done. the old function 'hide' did just that but a hide shouldn't delete anything. The third part is preferenes awareness for the PP graphs. I created two new functions that receive the settings key for visibility and use the QSettings to show / hide them. This also works quite well for the axis; if no graph is visible, the axis will also hide itself. The fourth part is colors. The pp graphs now have the correct colors. And a bit of code cleanup too.

2014-01-17Create a version of create_graph_info that doesn't depend on GC.Gravatar Tomaz Canabrava
This version of the create plot info is the same as before, with the difference that it doesn't depends on the gc. Also fixed a crash.

2014-01-16Whitespace and coding style updatesGravatar Dirk Hohndel
Another futile attempt to cleanup the code and make coding style and whitespace consistent. I tried to add a file that describes the key points of our coding style. I have no illusions that this will help the least bit... This commit should ONLY change whitespace Signed-off-by: Dirk Hohndel <dirk@hohndel.org>
2014-01-16Reworked the calculate_max_limits and plotted the dive.Gravatar Tomaz Canabrava
Created a new version of calculate_max_limits that doesn't have a graphics_context and returns a plot_info. The code is basically the same as the old calculate_max_limits, so there's not much to talk about. The rest of the code is just boilerplate to plug the Profile code with the axis and model stuff, to be plotted on screen.

2014-01-16Added a Model that should handle the Dive ProfileGravatar Tomaz Canabrava

2014-01-16Convert the C code to using stdbool and true/falseGravatar Anton Lundin
Earlier we converted the C++ code to using true/false, and this converts the C code to using the same style. We already depended on stdbool.h in subsurfacestartup.[ch], and we build with -std=gnu99 so nobody could build subsurface without a c99 compiler.

2014-01-08When interpolating tank pressures, don't devide by zeroGravatar Dirk Hohndel
When an interpolated segment is on the surface we get no pressure time - and try to divide by zero. (plus a small whitespace issue that slipped throught the cracks earlier) Signed-off-by: Dirk Hohndel <dirk@hohndel.org>
2014-01-08Reinstating SURFACE_THRESHOLD test in pressure_time functionGravatar Rodrigo Severo
The small straight parts at the end of tank pressure lines are more of a aesthetic issue, not causing real harm so it is no reason to remove the SURFACE_THRESHOLD test from pressure_time function only because of this. Also improved interpolate data debuging, rearranged get_pr_interpolate_data and removed an unused variable from get_pr_interpolate_data. No real change here, just trying to make the code clearer.

2014-01-08Discontinuity and stall on tank pressure interpolated linesGravatar Rodrigo Severo
Interpolated lines for tank pressures were presenting discontinuities (sudden drops) and stalls (horizontal lines) with certain dive profiles. The main reason seems to be that the discrete interpolation of tank pressure was adding small pressure increments that could be rounded down or up repeatedly generating cumulative rounding errors that would mean either a delay on pressure drop that would be drawn as a sudden drop or as a premature pressure drop that would result in a flat line. This patch changes the way the discrete interpolation is done, so that we don't have cumulative rounding errors distorting tank pressure lines. To calculate accumulated pressure_time values the get_pr_interpolate_data function was created. The fact that get_pr_interpolate_data transverses the beginning of the plot_info entry list for each entry that needs interpolated tank pressure isn't optimal at all. There might be a way to properly track the data necessary to interpolate tank pressures from inside the main pi->entry loop in fill_missing_tank_pressures. Unfortunately I didn't manage to do it inside fill_missing_tank_pressures so we have get_pr_interpolate_data. The SURFACE_THRESHOLD test from pressure_time function was also removed as no matter how shallow the diver is, if he is using the cylinder to breathe the cylinders tank pressure should be affected.

While playing with the ruler, I figured that it happened only once that my minimum speed was not 0 for a segment long enough to get any display. And it was a "dive" in an hyperbaric chamber...

2013-11-20Use get_cylinder_index in per_cylinder_mean_depthGravatar Anton Lundin
Use get_cylinder_index that handles SAMPLE_EVENT_GASCHANGE and SAMPLE_EVENT_GASCHANGE2.

2013-11-13Break up calculate_deco_informationGravatar Anton Lundin
Break the huge calculate_deco_information into three different functions. One for the current deco calculations, one for the ndl/tts/deco stop and one for the gas calculations. This makes it easier to disable/enable different functionality. This also gets rid if the ccrdive state variable, and keeps that state in the plot_data struct. Now we calculate the deco before we calculate the gas properties, so if we have a po2, we're in ccr-mode, and if we don't, we're in oc mode.

When moving along the plot, it's hard to look at a certain value when its place in the info box moves due to values being added or removed above it.

2013-10-09Next step towards working translationsGravatar Dirk Hohndel
This may seem like a really odd change - but with this change the Qt tools can correctly parse the C files (and qt-gui.cpp) and get the context for the translatable strings right. It's not super-pretty (I'll admit that _("string literal") is much easier on the eye than translate("gettextFromC", "string literal") ) but I think this will be the price of success.
