3D Starchart - Teaser 1: Rendering Planets

I was wondering why it wouldn’t work at all on my mechine, you just answered my my question though, I never installed FL on this desktop. I just dragged and dropped the install folder from another drive, so there is no registry entry.

So, when i rename my modded FL in “Freelancer” to make your soft parsing my files, no errors, the soft doen’t load, it say “Starchart a cesé de fontionner” (in english i think its’s equal to “starchart have stopped running”) this is the Details :
Description :
Stopped working

Animation when orientating systems and moving around are smooth zoom in and out too. Switching system take about 3 secondes. i will make more test to see how many times i can switch systems.

Hope details can help you to found problem, but i thing to a cast error like saying in the details, are you casting some values, or just manipulate them ? Good luck.
I cant take a look at your source code for now, cause i havn’t my compiler installed in this computer.

OK good news so

Oh, just a suggestion :
is there an easy way for you to let the user point at the FL folder instead of reading the registry ? So that, we can choose if we want load vanilla FL or a modded one :), By asking the user to point at the universe.ini or the freelancer.ini r the FL Folder.

It can be a cool option for your future release.

good work, just wondering is this going to be a kind of system editor?
cause thats what ive been working on. (tho not much recently due to real life)

Found another problem caused by JFLP. I use the longer “En Dash” (U+2013) for the gate “arrows”. This character isn’t present in the sprite font, so another exception is thrown. Solution is simple, add s = s.Replace(‘\x2013’, ‘-’); before MeasureString in drawString in SystemMap.cs. Well, simple for that particular problem, but there could be other missing characters, so a more robust solution is needed.

So i have maked some other tests :
Performaance seems to be good, i can change 25+ times of systemes, but some systems are unable, if you click on the map, nothing append, and on some systems, soft crach with the “system.exception” throwed.
And always this “cast exception” on a modded freelancer.

But the god side is that the perfprmance is rather good and system swytch are fast, on my computer.

I’ve taken the liberty of attaching an updated version. It should fix all problems reading ini files, as well as reducing memory usage (I could previously only visit three systems before running out). It also lets you hold down control to move five times quicker. Note: this is just the binaries, you still need the Content directory. Source patch included (from revision 109).

Good job to both of you I will make some other tests

Here’s another update. Greatly improves system selection, including showing the name as you move over it (although it has a horrible magenta flash each time, but that could just be me). Made the gate lines green (I had also intended to make systems with both gate & hole use yellow, but that wasn’t as simple as it sounded) and gave gates precedence over holes. Less strict model loading, so Omicron Alpha (and perhaps others) will load. Even more memory fixes. Improved font support (e.g. Lübeck in Hamburg). As before, this is just the binaries plus patch (for r116).

@obstbaum:

Nice job so far on this, i am having allot of fun working with it.

I am wondering though, if you have any ideas on how to go about using the left mouse button to select scene objects and have them highlighted like in FL when you select something. I tried a few ideas but nothing has really worked yet.

For what i am doing i added a combobox that is populated with all the valid system objects of which i can select items, move the camera close to it, and show the objects properties in a property grid. but i would prefer to use the left mouse button in the scene to select them instead.

I have also started extending the FLApi to add in a Faction Class, and classes for the Market ie:

FLApi.Market.Commodities, FLApi.Market.Ships, FLApi.Market.Equipement

i just started on them so no real code yet.

the Class: FLApi.Factions.FLFaction is working fine, all it really does though is to parse the initialworld.ini to retrieve the Proper name of factions. Although this will be extended to include a list of their reputations with other factions, which will be easy enough to do , just have not coded it yet.

I am also working on extending the Costume class , which so far was a simple thing since you already had the code in place and parsing out those lines anyway. Again, plans are to extend this Class.

Because of the project i am using these in i had to convert the Starchart project into VB.NET, but somewhere along the lines of the conversion process something went wrong and now Planets are not being physically rendered in the scene, which also has a side effect of messing up the scene lighting. I have not really delved into this problem too much.

Anyway Cheers, and nice job so far.

WoW! Its amazing!!! Whats left now is the fields, suns and maby even effects… Too bad I can’t help you…

Well i am casting a ray from the mouse x,y into 3d space. this is the function that handles that:

Ray GetPickRay()
        {
            MouseState mouseState = Mouse.GetState();

            int mouseX = mouseState.X;
            int mouseY = mouseState.Y;

            Vector3 nearsource = new Vector3((float)mouseX, (float)mouseY, 0f);
            Vector3 farsource = new Vector3((float)mouseX, (float)mouseY, 1f);

            Matrix world = Matrix.CreateTranslation(0, 0, 0);

            Vector3 nearPoint = GraphicsDevice.Viewport.Unproject(nearsource,
                proj, view, world);

            Vector3 farPoint = GraphicsDevice.Viewport.Unproject(farsource,
                proj, view, world);

            // Create a ray from the near clip plane to the far clip plane.
            Vector3 direction = farPoint - nearPoint;
            direction.Normalize();
            Ray pickRay = new Ray(nearPoint, direction);

            return pickRay;
        }

the problem comes in when i loop through all the objects in the scene to get the object that is suppose to be selected the result value returned from ray.intersects is always : -1.#IND

so i tried changing the farSource to be the static system size, which does not really work at all except to move the camera to above the sun, or in the case of New York System, sometimes above West Point (mostly though is ends up above the sun)

forgive my ignorance of XNA here, i have not done allot with XNA so still feeling my way around to a large degree.

and for the planet rendering issue, i am not at all sure what is going on, the code is pretty much identical (just written in VB.NET not C#). As i said, the Planets are being added as valid system objects but just nothing rendering, or maybe they are rendering but could it be that the ‘scale’ of the planets is not being calculated right? not sure to be honest, my code matches yours so not sure what i am doing wrong.

I may try changing my app into C# and see if that changes anything.

to your question about why VB.NET instead of using C#? well mostly because i am more comfortable in VB environment. Nothing to do with the language or anything. And secondly, because i can. Also because there is a few quirks about C# i am not fond of.

Don’t get me wrong though, i can code in C# just as well as VB or C++.

well well, i will be a g*&&^ d&^*&^& monkey’s uncle.

i did a quite conversion to C# of part of my project and bang, planets and proper lighting.

so i am moving forward to redo my project in solid C#.

anyway just thought i would let you know , cheers.
