What does an inverted depth buffer provide? Image analysis? Eases calculations of screen space effects? The other graphical features you listed are really exciting sounding! smile

That's actually exactly what I was wondering. An internet search provided no results.

I dont see any of this: ``- Upgraded ship editor - added options to add and remove elements and save changes to scripts´´

The download is automatic?

Yeah, an Internet search didn't do me much good either.

The last thing needed to upgrade is orbital path rendering, and I will be able to move to OpenGL 3.3. This opens a lot of possibilities: change to deferred shading with all modern effects (inverse depth buffer, ambient occlusion, indirect lighting, soft particles etc), multi-sampling antialiasing, SLI and CrossFireX with no performance drop


This is extremely important!!
This is beyond every gift we could recive. Great job Vladimir!!!
Soft particles? orbital path rendering? that sounds awesome, but please tell me what implications could have that so I can drool
yahoo

- Newly built ship spawns with the same speed as the currently selected one


Thank you for that!

Today I also implement "Sync velocity" commend for ships. It works in two stages:


Excellent!

Can we select other spacecraft as our point of reference, too? So far, hitting "p" with another ship selected has no effect. I frequently like to rendezvous spacecraft (Space Shuttle to the ISS or Hubble, for example) and zero-out their relative velocities. While there's a certain satisfaction to eye-balling it, an indication of our relative vector would be most welcome.

It allows to remove z-fighting artefacts on water shores, remove near plane clipping (so allows to approach to a space ship or planet surface to a distance of a few millimetres), allows to finally implementing particles correctly intersecting with planet surface (3d clouds, volcano eruptions, ship engines smoke etc). It allows to have a single z-buffer for the whole scene, which enabling possibility to implement shadows and deferred shading with all effects which it can introduce (hundreds of local light sources, 3d water with refractions, huge increase in atmospheric scattering performance, etc). Also, correct blending of large planet-scale particles with planets (comets tiles, and future accretion disks and jets). Did you think why I still don't implement all these effects? Because SE have too large scene scale to work with standard z-buffer.

The right term is the "reversed z-buffer". More hardware-friendly and no-performance-impact replacement of logarithmic z-buffer. The last is implemented in SE, by disabled by default, because have too large fps drop.

Of course not. I didn't upload the patch, this is just like a development blog.

No. Reference object can't be selected by user now, because of change in physics I made in 0.97. Some additional work is required to return this possibility back.

And to me, inversed Z-buffering sounded like some minor technical feature that would optimize things a bit and fix bugs here and there. Guess I was wrong, lol.

WOW! work space engineer is spectacular! many new features in no time, so continue!

Well, you had to post it in the thread work in progress, space engineer wants all bugs are reported them

Yes yes! that sounds awesome, keep working at it as I'd love to see better shading!

Uh, I'm having a bit of trouble with 'alien-like' lights.





They appear most often near planets, but when you go away from them they stay until you get what looks like about a light year away from the star. They are greatly brighter in normal exposure, but I turned the exposure down so you might be able to decipher their nature. They only appear at certain angles, and have only occurred halfway through having the .3 patch, and have continued into the .4 patch also.

Screen space subsurface scattering?? surprised Ambient Occlusion? Indirect lighting?!?! You could implement things like heatwaves too, I bet! Caustics, dynamic focus... I've even seen screen space fluid demonstrations, but I have no idea how that really works.

This is really awesome!
