e00b4a58e1
Fixed problem with bodies rendered as points always appearing in front of larger objects in the old star render path.
2006-09-26 17:30:49 +00:00
436cb8e2d6
Fixed another depth sorting issue and eliminated some unused code.

3eb580abe9
Commented out unused variables that were causing compiler warnings
2006-09-12 12:56:47 +00:00
0e03ec8999
Added polygon offset to cloud layers so they aren't as susceptible to z fighting when depth buffer precision is limited.
2006-09-12 05:27:29 +00:00
79232ff174
Fixed depth sorting of comet tails and stars.

galaxy labels with distance dependent transparency
2006-09-11 21:47:01 +00:00
76081d6603
Implemented two pass approach for rendering: opaque objects are rendered first, transparent ones second. Subpixel sized objects are also rendered with transparent objects and after orbit paths. This fixes the problem where orbit paths were occluding point sized objects.
2006-09-11 00:37:20 +00:00
23b392364d
Fixed some broken logic that displayed the orbit of the select object even when orbits paths were turned off. Enabled highlighting for the orbit of a selected star.
2006-09-10 03:54:43 +00:00
8c5a08f26a
Depth sorting and orbit fixes:
...
- Show and highlight orbit of selected object
- Show star orbits
- Remove depth sorting debug spew
- Correctly orient orbit paths when the orbit is referred to the ecliptic rather than the parent body's equator
2006-09-08 05:59:38 +00:00
aa9c6a3c64
- Replaced the old depth sorting algorithm with a new, cleaner, faster, and more robust scheme.
...
- Overhauled orbit path rendering so that orbit paths get correctly depth sorted
2006-09-07 08:08:32 +00:00
08b80c2c89
Worked around a precision problem in the new atmosphere code that appeared when the camera was positioned far from an object relative to the size of that object.
2006-09-02 18:56:41 +00:00
097640abc6
Halved the minimum relative occluder radius used to decide whether an object should be considered for eclipse shadows.
2006-09-01 11:14:37 +00:00
1fc8c42ecb
- Implemented normal maps for cloud layers. The new field CloudNormalMap specifies the texture file to use.
...
- Don't render ring shadows on cloud layers when ring shadows are disabled
2006-09-01 10:14:08 +00:00
1cc0b38fde
Enable new atmospheres to work for irregular objects.
...
Moved parameter setup for atmospheres, lighting, and shadows into the CelestiaGLProgram class.
2006-08-29 06:13:41 +00:00
243ba06154
- Split the GLSL code out of render.cpp and placed it in its own file.
...
- Adjusted the atmosphere extinction threshold upward; slightly improves the appearance of atmospheres without introducing tessellation artifacts
- Fixed some clipping problems with the new atmosphere code (though there are still problems when the camera is very close to a planet's surface.)
2006-08-26 23:58:48 +00:00
c23d15a4e4
Made LunarLambert term apply to models instead of just ellipsoid bodies.
2006-08-09 06:12:41 +00:00
856a05d6f6
Added lunar-Lambert photometric model for much more realistic rendering of the moon and similar bodies.
2006-08-08 17:19:57 +00:00
370655d004
Enabled opacity attribute in the OpenGL 2.0 render path.
2006-08-07 17:23:09 +00:00
27bfdea411
Added new photometric functions and atmospheric scattering model.
2006-08-07 06:40:45 +00:00
9389ea3b78
- Fixed bug in the eclipse shadow test; objects close to the surface of the lit side of a planet were incorrectly rendered with shadows
...
- Added a render flag for cloud shadows
- Made the OpenGL 2.0 path respect the ring shadow render flag setting
2006-07-26 17:21:23 +00:00
29fe230880
Made mesh objects with the emissive flag set render correctly in the OpenGL 2.0 path.

d9c6dd5544
Turn off cloud shadows when cloud maps are disabled.
2006-07-13 16:23:06 +00:00
063ec093d3
- Implemented cloud textures
...
- Changed eclipse shadow shaders to use just a single interpolant for all shadows rather than one interpolant per shadow. This will prevent Celestia from generating uncompilable shaders when there are many eclipse shadows
2006-07-12 17:39:24 +00:00
f3326dd39f
- Added per-pixel specular lighting for GLSL path; can work either with or without bump mapping
...
- Turn on separate specular color when rendering models (not required for GLSL path)
- Fixed completely broken calculation of object space eye position for GLSL shaders
2006-07-09 02:03:29 +00:00
dc7ce8986a
Improved rendering of meshes in GLSL path:
...
- Switched to local viewer model for better quality specular highlights
- Added support for specular and normal maps for meshes
- Implemented shadows for meshes (cast by ellipsoids only, not from other meshes yet.)
2006-07-04 05:03:27 +00:00
b7cc62512b
Fix some depth sorting problems. Coaslescing depth buckets was failing when a coaslesced object was clipped to the near plane. Implemented a partial fix for the problem allows the coalesced depth buckets to have a larger far/near ratio.
2006-06-27 07:51:20 +00:00

Localize planet labels

Made overlay textures work in the GLSL render path.
2006-05-17 10:21:58 +00:00

Fixed a crash that occurred when stars-as-points mode was set while a legacy render path was enabled.
2006-04-20 16:32:05 +00:00
1184a99a59
Disable new star rendering code when a pre-vertex shader render path is enabled. Fixes a crash.
2006-03-23 07:31:25 +00:00
612419cd2b
Fixed point stars in new star rendering path--now they're rendered as points instead of colored squares.
2006-03-15 18:46:34 +00:00
4fa5c3475f
Enabled new star rendering path as an option--uses point sprite extension, new glare textures (gaussian), and dynamic star labeling.
2006-03-08 18:29:10 +00:00
03c872017a
fixed local brightness flash for Milky Way
2006-01-03 17:22:07 +00:00

fix for displaying the furthest galaxies in deepsky.dsc, with distance > 1e9 ly
2005-12-19 23:04:28 +00:00
0493b69176
add comet tail vanishing code, distance sorted label display
2005-12-11 15:34:35 +00:00

Integrated changes from Fridger and Toti's Celestia FT 1.2
2005-11-18 09:00:39 +00:00
f5f14ee5ab
Render orbits paths in multiple passes so that they are drawn correctly when they appear in front of a planet or other body (another Joseph Wang fix)
2005-07-25 16:38:09 +00:00
ae7095edd7
Added i18nName to the Asterism class and a renderer label flag to display
...
localized names of constellations.
Removed some redundant calls to gettext when rendering labels
Added KDE menu entry and preference to toggle I18nConstellationLabels
2005-07-21 22:35:18 +00:00
6f037cd9b4
Increased far plane distance by factor of 100 to avoid clipping distant galaxies.
2005-07-21 16:31:43 +00:00
2318e423a3
Adding support for i18n with gettext.
2005-07-19 21:31:04 +00:00
3fb7a9c689
- Add context as a parameter when rendering deep sky objects (required in order to use shaders)
...
- Add absolute magnitude for deep sky objects
2005-07-12 17:37:00 +00:00
5857865126
Added support for emissive textures for mesh objects (and foundation for further improvements for mesh rendering.)
2005-03-09 16:38:45 +00:00
57ff878447
Added separate render and label flags for the various types of deep sky objects. This will break some scripts and cel:// URLs that relied on the 'show galaxies' flag to also show nebulae, but this is the inescapable cost of moving to a more flexible set of render settings.
2005-02-11 06:09:37 +00:00
3c3425ef60
- Fixed bug in OpenGL 2.0 that was causing planets to appear completely dark when there was an eclipse and more than four light sources
...
- Use enumerants for the ARB version of the texture_env_dot3 extensions; this fixes bugs with normal maps on some Mac OS X drivers which no longer support the EXT version of the extension.
2004-11-12 06:50:04 +00:00
384e3ca8b7
Fixed lighting bug that occurred when multiple solar systems were rendered. Solar system centric light source positions from the wrong solar system were being used, resulting in completely incorrect illumination.
