I've been working to make the 3d render a little more accurate, for example body tubes have 0 thickness right now, so I am giving them an outside, an inside, and end caps. I would like to make the fins have an appropriate cross section (Square, round or airfoil). I know it is not that important, but it'd look nice. OR does not allow for anything really fancy for fin cross section, does it? For example the honest john ( http://olive-drab.com/images/firepower_honest_john_700_01.jpg) has a pretty specific cross section that I don't think can be specified in OR, correct? Thanks, Bill |

Bill, Should body tubes have end caps? I think they should not. If you need an end cap you would use a bulkhead component. I don't know of any way to have fancy fin cross sections.

Why would you want body tubes to have end caps? What purpose would that serve in a rocket?

Hi, The simulation routines handle body tubes effectively like they would have end caps. In that sense the 3D model would more accurately represent what is being simulated. However it is different from what one would expect, and especially the rear end might look strange if the body tube is capped. Ideas? Maybe the front end or midpoint could have a black cap to indicate that air doesn't flow through the tube? Then again if the ube is otherwise blocked, you have the same effect but it looks weird... - Sampo N.

Since OR doesn't support tubes outside the main body tube (ring fins, tube fins, pods), it seems that during ascent, the nose cone is effectively the cap on the front end and the rear centering ring would be the cap at the back end. I think it would seem very weird if a capped tube were displayed when that's not how it was built at all.

Sorry I did a terrible job explaining the "End Cap"! Before the body tube was just rendered as an infinitely thin cylinder with the OD as its radius. Now I draw a cylinder with the OD, a cylinder with the ID, and then the "end cap" is a ring that connects the two. -Bill On Tue, Mar 5, 2013 at 11:07 AM, Kevin Ruland <kr...@su...> wrote: > > Since OR doesn't support tubes outside the main body tube (ring fins, tube > fins, pods), it seems that during ascent, the nose cone is effectively the > cap on the front end and the rear centering ring would be the cap at the > back end.

That makes sense... Would you not have to fill in the area between the two cylinders as to get an accurate weight? Because if you have the volume as hollow, that would mean an inaccurate CG of the rocket in extreme cases.

Matt, Computation of mass based on density is handled correctly. This is purely a visualization problem.

Hi, That explains. :) But it gave me an idea for future development: An aerodynamic view. This could show the rocket in the way it is effectively simulated (for example ignoring internal components and body tubes capped. The component color can indicate the drag force produced by the component and the fore/end caps separately colored. (May need extending the aerodynamic computation a bit to split these up.)

That sounds very cool. I was going to try it out right now but when I tried to trace the logic from component analysis to rocket panel my brain melted. Then I saw that changing the Wind Direction rotates the 2d model and thought I should do that, and I could also show AoA somehow.... I hope you don't take offense if I mention that the way all of the UI things get plumbed together can get really confusing sometimes. -Bill On Tue, Mar 5, 2013 at 3:16 PM, Sampo Niskanen <sam...@ik...>wrote: > Hi, > > That explains. :) > > But it gave me an idea for future development: An aerodynamic view. > This could show the rocket in the way it is effectively simulated (for > example ignoring internal components and body tubes capped.

Hi all. Sampo, I looked at you configuration changes both the new code and ui look nice. I was thinking that we should start consolidating the various code bases so we can do some real beta testing. There are currently 3 'integration' branches, tumble recovery, I have a branch with some of Boris' l10n changes, and he has his own too. Also I have an old branch with the online library client code, though there are currently no servers for this. (And I was wondering if we should go with WebDAV instead of XML/http.) I would like to start playing with all the code together and provide some beta builds to adventuresome folks. Kevin -- Sent from my Android phone with K-9 Mail. Please excuse my brevity. |
