11:27 pm Feature #621: Better sun visualization
- I've improved the appearance of the current crepuscular ray shader. The problem was the math just didn't pan out prop...
-
06:07 pm New Nightshade Website
- The Nightshade project now has a new website design which should allow much easier interaction and participation with...

-
- As part of this, I'm looking into improving the current fragment shader used on 3D stars. It looks pretty good when t...
-
- OK, got it. Just a one time copy.
-
- Are you referring the the need to copy it? Copying it manually this time stems from the fact the NS12 will not even l...
-
- Why isn't the user's config file updated in place?
10/04/2012
-
- Saving current settings and loading default settings is implemented. The buttons are currently in the settings window...
10/03/2012
-
- Catalog ID field and catalog abv field for object info display. Will require new catalog extractions.
-
- Only thing missing I'm aware of is Spectral Type on stars. For some reason I didn't put this field in the new databas...

-
- Just azi/alt readout and full year datetime remain in progress.
-
- There were a couple problems in the calculations for the grid orientation. The labels may still increment in reverse ...
09/29/2012
-
- Plx, B-V and distance fields (in physical coordinates) implemented. Also implemented text color change to selected st...

-
-
- This is a limitation of the current nvidia drivers (probably similar on other drivers). gl_PointSize is clamped to an...
-
- The sun magnitude calculation case was simply in the wrong units.

-
- Español
-
- This is a safety mechanism since otherwise NS will not run.
09/25/2012
-
- Rob, I don't see any accessible way to do that. Given the current design these are mutually exclusive requirements.
-
- Draw order changed. Will draw after all 3D content but before UI layers.
-
- Name and RA/DEC readouts are implemented. RA/DEC currently J2000 for all objects relative to observer (seems to match...
-
- It's more subtle than that. Grid lines ideally should match NS11 behavior. That means drawing behind planets, but i...

06:23 pm Bug #1705: Atmosphere draws on top of azimuthal grid
- Discussed with Rob: lines and grids should draw on top of everything. NS11 has that implementation, and it's useful ...
-
-
- This is in conflict with Rob's request to have the grids render on the celestial sphere, behind planets.
-
-
- All grid lines should render in front of atmosphere.
-
- Ok, pretty sure I fixed the root problem. The current pitch was being calculated in a way that didn't always yield th...

-
- Have a working end to end unit test. Can select the Sun, anchor it (fly to it), and then increase distance beyond sol...
09/21/2012
-
- Working out some final issues with this but seems to be working fairly well. Can fly to Sun and then increase distanc...
-
- It might be helpful to define a header format to include a computer readable NS version required to successfully run ...
-
- Can now increase distance outward and have the expected scenes swap in. However, decreasing distance back toward the ...
-
- This was due to attempting to load osgEarth instances via separate threads. Removed this optimization for the time be...

-
- Correct, this has nothing to do with fisheye. It's just intermittent. If you see it then exit and restart for now. Se...
-
- I also believe that fisheye was not scoped until DR
-
- I noticed this as well. I had to rebuild my scene and install the rebuilt scene, and then I got the earth and mars b...
-
- Find Earth, CTRL-G. It will usually fly past the Earth rather than too it, then possibly jump to tracking it. Can n...
-
- User can replace milkyway image sphere around the solar system, and this is how we can currently implement WMAP. It ...

-
- Needs further discussion.
-
- Fade them out after leaving atmosphere bounding volume.
-
- Parity with current NS11 meteor shower behavior.
-
- Already implemented Nightshade12 via the 'follow' ALG-f mode.
-
- No, YOU do it. I'm not doing it.
RESEARCH :-) -
- No, you do it.....no, you do it! Someone do it!! :-D
-
- repository requires refactoring
-
-
- Ability to place TUI at different locations around horizon.
-
- For realism, this would allow at low moon phases for the moon to still be visible. It's the reflection of the sun's ...
-
- Plus shadows for Saturn ring shadows (see Rob's shader, two shaders one for shadows on each element saturn-body and r...
-
- This would allow for the arbitrary creation of lines in space, coordinate systems, labels for any object, etc.
-
- See Rob's fragment shader, should be able to inject when building the solar system scene. Special case of red tint (u...
-
- This is currently available for Earth and Mars with high-res terrain data, but not with other planets. This relates ...
-
- Consider a comet tail effect as well with relation to the sun
-
- Atmosphere dims relative to eclipse amount. This should be doable via the ISun uniform in the PCAS shader. Will also ...
-
-
- Unclear on how we want to implement this. Do we want to implement an orbit path, or a reverse trail?
-
- A 3 term polynomial approximation is currently used. The coefficients reside in distortion.dat.
-
- Try changing current off-screen texture to HDR first and using that. I.e. add a global HDR stage to render off-screen...

-
- If you hit ALT-d you can see a readout of your current orientation. Heading is of course only valid when anchored to ...
-
- Behaves nicely now. Prior to the change just a handful of ad-hoc control points were used to animate the camera. This...
-
- When on a planet with atmosphere the stars should twinkle. When above the atmosphere or in space they should not.
... -
- Can there be an easy readout of the current pitch and heading? Also, how are we dealing with Yaw?
-
- I can no longer reproduce the case that I was seeing. I did find one more nav error, though:
Any time you drag th... -
- Changing this to resolved instead of closed to track for testing.
-
- Arthur, can you try to repro with the current mainline? I'm not sure what would have changed but I'm having trouble r...
-
- One problem was multiplying the eye - pos vector by a multiplier. This is accounted for in the projection matrix whic...

- 09:54 pm Task #1472 (Closed): Look into PBOs for video capture
- 09:54 pm Bug #1566 (Closed): set home_planet usually changes view to random direction
- 09:54 pm Task #703 (Closed): External configuration file
- 09:54 pm Task #699 (Closed): Implement event handlers to allow simple free movement
- 09:54 pm Task #696 (Closed): Coordinate system definitions

- This problem is more visible than on Earth since Mars lacks water filling such areas and thus has lots of negative el...
-
- Mars is fixed, although it demonstrates an additional problem of atmosphere shader behavior below 'sea level' (gap re...
-
- Custom atmospheres are possible, but they are still based on Earth scattering effects.
Other planets to add atmosp... -
- By creating new sky cultures, you can add markers around stars with exoplanets and the like, but hopefully we'll have...
-
- Although we now have the ability to run the comets script, I think that the simulation should include these as defaul...
-
- Depending on the lesson being shown, it would be useful to simply have multiple presets to switch to the next part of...
-
-
- Text code for this lives in Nightshade planet.cpp actually, but never turned it on. Suggest waiting for NS 12
-
- A user is working on a rainbow lesson, and she want to be able to completely remove the sun while still being able to...
-
- It'd be useful to scale both the body and the entire planetary system.
This is especially useful to showcase rotat... -
- The ability to enable only certain planets/bodies in the database to show just the planets that ancient observers had...

- Gap is fixed. We'll see how the fix hold up over more testing, it's a little sneaky. Basically, I'm telling the shade...
