yasim_import.py loads and visualizes a YASim FDM geometry
=========================================================
It is recommended to load the model superimposed over a greyed out and immutable copy of the aircraft model:
+ (0) put this script into ~/.blender/scripts/
(1) load or import aircraft model (menu -> "File" -> "Import" -> "AC3D (.ac) ...")
(2) create new *empty* scene (menu -> arrow button left of "SCE:scene1" combobox -> "ADD NEW" -> "empty")
(3) rename scene to yasim (not required)
- (4) link to scene1 (F10 -> "Output" tab -> arrow button left of text entry "No Set Scene" -> "scene1")
+ (4) link to scene1 (F10 -> "Output" tab in "Buttons Window" -> arrow button left of text entry "No Set Scene" -> "scene1")
(5) now load the YASim config file (menu -> "File" -> "Import" -> "YASim (.xml) ...")
This is good enough for simple checks. But if you are working on the YASim configuration, then you need a
quick and convenient way to reload the file. In that case continue after (4):
- (5) switch the button area on the bottom of the blender screen to "Scripts Window" mode (green python snake icon)
+ (5) switch the button area at the bottom of the blender screen to "Scripts Window" mode (green python snake icon)
(6) load the YASim config file (menu -> "Scripts" -> "Import" -> "YASim (.xml) ...")
(7) make the "Scripts Window" area as small as possible by dragging the area separator down
(8) optionally split the "3D View" area and switch the right part to the "Outliner"
model animation XML file should be added as comment to the YASim config file, as a line all by
itself, with no spaces surrounding the equal signs. Spaces elsewhere are allowed. For example:
- <!-- offsets: x=3.45 y=0.4 p=5 -->
+ <offsets>
+ <x-m>3.45</x-m>
+ <z-m>-0.4</z-m>
+ <pitch-deg>5</pitch-deg>
+ </offsets>
+
+becomes:
+
+ <!-- offsets: x=3.45 z=-0.4 p=5 -->
Possible variables are:
Of course, absolute FDM coordinates can then no longer directly be read from Blender's 3D view.
The cursor coordinates display in the script area, however, shows the coordinates in YASim space.
-Note that object names don't contain XML indices but element numbers. YASim_hstab#2 is the third
-hstab in the whole file, not necessarily in its parent XML group. A floating point part in the
-object name (e.g. YASim_hstab#2.004) only means that the geometry has been reloaded that often.
+Note that object names don't contain XML indices but element numbers. YASim_flap0#2 is the third
+flap0 in the whole file, not necessarily in its parent XML group. A floating point part in the
+object name (e.g. YASim_flap0#2.004) only means that the geometry has been reloaded that often.
It's an unavoidable consequence of how Blender deals with meshes.
Elements are displayed as follows:
cockpit -> monkey head
- fuselage -> blue "tube" (with only 12 sides for less clutter)
- vstab -> red with yellow flaps
- wing/mstab/hstab -> green with yellow flaps/spoilers/slats (always 20 cm deep);
- symmetric surfaces are only displayed on the left side
+ fuselage -> blue "tube" (with only 12 sides for less clutter); center at "a"
+ vstab -> red with yellow control surfaces (flap0, flap1, slat, spoiler)
+ wing/mstab/hstab -> green with yellow control surfaces (which are always 20 cm deep);
+ symmetric surfaces are only displayed on the left side, unless
+ the "Mirror" button is active
thrusters (jet/propeller/thruster) -> dashed line from center to actionpt;
arrow from actionpt along thrust vector (always 1 m long);
propeller circle
- rotor -> radius and rel_len_blade_start circly, direction arrow,
- normal and forward vector, one blade at phi0
+ rotor -> radius and rel_len_blade_start circle, normal and forward vector,
+ one blade at phi0 with direction arrow near blade tip
gear -> contact point and compression vector (no arrow head)
- tank -> cube (10 cm side length)
- weight -> inverted cone
- ballast -> cylinder
- hitch -> circle (10 cm diameter)
+ tank -> magenta cube (10 cm side length)
+ weight -> inverted cyan cone
+ ballast -> yellow cylinder
+ hitch -> hexagon (10 cm diameter)
hook -> dashed line for up angle, T-line for down angle
launchbar -> dashed line for up angles, T-line for down angles
+ (launchbar and holdback each)
+
+
+The Mirror button complements symmetrical surfaces (wing/hstab/mstab) and control surfaces
+(flap0/flap1/slat/spoiler). This is useful for asymmetrical aircraft, but has the disadvantage
+that it moves the surfaces' object centers from their usual place, yasim's [x, y, z] value,
+to [0, 0, 0]. Turning mirroring off restores the object center.
+
-Cursor coordinates displayed in GUI and terminal are in YASim coordinates and consider an
-XML embedded displacement matrix as described above.
+Environment variable BLENDER_YASIM_IMPORT can be set to a space-separated list of options:
+
+ $ BLENDER_YASIM_IMPORT="mirror verbose" blender
+
+whereby:
+
+ verbose ... enables verbose logs
+ mirror ... enables mirroring of symmetric surfaces
