Update from Mike
Hey guys a new update from Mike:
This time also a bunch of short videos:
Quote:
a lil video preview of the progress so far... these are the first tests of sub hull and interior composited together into a single functional unit in the game/sim...
over the next few hours (days) i'll be posting several short videos of the sub running and diving as i get em working...
the first video shows basic bouyancy properties of the submarine as it is dropped into the game... there is also a quick peek inside the sub to show that the rolling and pitching action of the sub on the surface is apparent to the crew inside (my attempt to add to the immersion factor)...

now keep in mind... this is still early in the project (even though it seems as if i've done quite a bit already) and most of the textures and figures are placeholders, and merely close representations of the final stuff...
the ocean fog has been removed for testing, and the lighting is set for the sub interior at night, even when viewing the scene from outside the sub...
the ocean is still visible when inside the sub and on the surface...
shadows still need work... and the dive planes you are seeing are oversized to help in tweaking... they are not representative of those found on a TypeXXIII UBoat...
the sub is controlled by the crew with references to instruments and gauges inside the sub... there will be no gui to speak of... there is a simplified ballast system where you can flood negative... close vents and pump to neutral... and blow to positive...
there are also dive planes and a rudder which also affect the movement of the sub above and below the surface...
next lil video shows the submarine vertically submerging by "flooding ballast" tanks only...

bouyancy is enabled using physics (ODE) in 3DRAD and adjusting mass of submarine rigidbody object...
next, vertically surfacing... again, by "blowing ballast" only...

here's one more showing the sub running on the surface...
and the last one showing the last bit of work i'll probably be able to finish today... this video shows the sub diving under power, using negative ballast and the dive planes for a quick dive... the dive planes don't become effective until the sub reaches a certain depth, and their effects are dependant on the the hydrodynic force caused by the speed of the sub...
(click on image to view short video)
after tweaking everything i'll be returning to fitting out the interior... adding working gauges... and (arrrggghhh, the most painful) getting some proper crewmodels and animations...
after that, well... honestly, that's a lil far to see clearly right now...
--Mike
