Mius-Front Tactical diagrams and armor penetration charts

A pair (unit and weapon) is required for displaying tactical diagrams and armor penetration charts in a tactical battle. In game: select a unit, it should have a target (orange line). Or second option, select a unit and point at a visible target in the line of fire mode [~]. In figure the pair is KV-1S (diagram is drawn for it) and Pak-38 gun. Diagrams and charts are shown by using [ } ] button



Vertical portion - armor penetration chart similar to the one shown in the encyclopedia, level of armor penetration is shown vertically, distance - horizontally. Horizontal blue line indicates the armor level of the projection from the direction of the target for the selected part of the vehicle (lower hull, top hull, turret). The example in figure shows top hull selected. To toggle the vehicle part click [RMB] on the tactical diagram toggle button. Broken lines indicate the level of armor penetration for gun projectiles (yellow line - APCR, red - armor-piercing).



Orange arrow indicates the distance to the gun - 320 m. Red dot - indicates current position of the selected tank part in the coordinate system of the chart. If the red dot is below the broken line, the projectile indicated by the line penetrates the selected vehicle part from the given angle and distance. Figure shows that PzGr.40 projectile penetrates from this distance, but PzGr.39 projectile - does not.
Horizontal portion is the tactical diagram. It shows from what distance and what angle the gun projectiles penetrate the selected vehicle part. The distance axis is along gray lines, represented by tear-shaped curves in each quadrant (front, rear, left, right). Each tick mark corresponds to 100 meters distance. Yellow and red lines indicate the distances of armor penetration for two types of gun projectiles (colors are similar to the armor penetration chart).



Orange arrow indicates the position of gun. If the blunt end of the arrow is located inside the the closed line, then the gun penetrates the selected vehicle part with this projectile from current angle. The figure shows that only PzGr.40 projectile (yellow color) is able to reliably penetrate the front and rear. And sides can be penetrated by two projectiles (PzGr.40 - from 700 m, PzGr.39 - from 500 m).
The chart and diagram are connected to each other along the axis indicated by the orange arrow - the ideal direction from which the gun projectiles will hit the tank.

If you calculate the angle of impact for the impacted polygon and adjust the angle based on shell caliber Vs the armor thickness, you have a winner (solid shot). The only way to calculate a game more accurately is if every polygon contains density data. Spalling would be a separate calculation.

I have no doubt Graviteam did there homework.

We do this in every game since 2004. This is elementary.
In GTMF also considered a contact place of projectile head shape (not a material point) with the barrier/armor.

This is also done for each texel, using the armor map. Here, too, there is nothing difficult.

Apologies to andrey12345 and Graviteam if you think that I assumed you do not use this logic. My comment was assumed to say that 'this' method is how to make a game as realistic as a SIM.

Players and fans post images that mean nothing to beginning players but show a deep detail level. Asid's post shows a level of detail that the average player will miss.

I think Graviteam has still not forgiven my bad spelling and attitude between 'Steel Panzers' and 'Steal Panzers'. Perhaps my post was back handed, but it was meant to be a compliment.

I'm just stating a fact :), taking into account the slope and armor thickness at each point it is a very simple matter. Intersection with the shell that have size and not just a material point - it is more difficult.
