The graphical improvements in the next version are amazing, especially those nebulae - the second picture looks like something straight from Hubble.

(Sorry for the double post)

Also, do stars inside the nebula illuminate it?

SpaceEngineer, these nebulae look really great but will they have textures in the future, so we can have real nebulae? these are probably diffuse nebulae, did you already do any planetary?
What do nebulae look like with this new hdr and bloom?

No, and it is very complex question, how to integrate stars into nebula. You have to convert them to a sdf somehow (signed distance function).

This is very complex too. First, how will you generate a 3-dimensional shape using only a photo? Second, how will you convert it to sdf?

Thanks for the answer!

Those look amazing! Good work! :)

If I may ask, what version of OpenGL will 0.9.8.1 require?
Specs: Dell Inspiron 5547 (Laptop); 8 gigabytes of RAM; Processor: Intel® Core™ i5-4210U CPU @ 1.70GHz (4 CPUs), ~2.4GHz; Operating System: Windows 7 Home Premium 64-bit; Graphics: Intel® HD Graphics 4400 (That's all there is :( )

Is this planetary nebula being modeled as a torus seen from above? I would think they're supposed to be spherical bubbles which are opaque at the edges and transparent in the middle, so they should look the same from all angles.

Recently I have working on a proper HDR with autoexposure, and adding a new shiny bloom effect. In process, improved quality of MSAA, and many other things. Now, finally, SE is able to display very large difference of brightmess, and true relative brightness of objects.

Earth and Moon. Relative brightness must be adjusted for all Solar system bodies. More precisely, scripts will have a physical-based parameters for textures calibration. Something like MinPixelBright and MaxPixelBright in some physical units like luxes.

scr00323.jpg

Saturn and Titan. No stars visible!

scr00325.jpg

Pluto and Charon. Stars are visible (although their brightness is still not calibrated, so this may be wrong).

scr00324.jpg

Saturn and Mimas with shiny glow.

scr00296.jpg

scr00295.jpg

Earth's night side. Atmosphere is glowing not in red color, as expected... I have to tweak the atmospheric scattering code. There is a tail of the comet Encke visible in top left (comets brightness is not calibrated yet).

scr00329.jpg

ISS over night side of the Earth. Starry sky, city lights, aurora, clouds and ISS are illuminated with a moonshine. I can use real photos from ISS to calibrate such scene.

scr00297.jpg

When ISS enters sunlight, it looks almost like explosion, until virtual "eye" adapts to a high brightness.

scr00298.jpg

Ship's light in the "night". Looks too shiny? Radiator's glow is too bright and too hot, it must be separated in its own texture, controlled by the graphics engine.

scr00330.jpg

Engine exhaust looks extremely bright, because its brightness is calibrated for the the next picture.

scr00331.jpg

In the "day", engine exhaust is barely visible. This is why its brighness was so extreme. Radiators glow and lights are completely invisible.

scr00332.jpg

Molten planets looks interesting in the Solar system browser.

scr00327.jpg

Glowing lava now looks really "glowing" (that is a planet in the sky, but it is so bright compared to the night moon's surface, so it is being overexposed).

scr00328.jpg

"Interstellar-style" black hole looks much better with a new bloom.

scr00294.jpg

With HDR, it is now easy to explore extremely bright object such as stars and accretion disks. Autoexposure speed is a bit too slow in this case (and adaptation back to starry sky), I have to derive a better formula.

scr00326.jpg

yes
YES
YES!!
keep up the beauty work !!

This depends on a star. If it is a solitary red giant, slowly losing its envelope, then nebulae might be spherical. If it is a fast rotating star or a binary system, shape might be more complex, typically, something like a tube. Magnetic fields are also affects the shape.

is the ISS a fixed orbit spacecraft always around earth now, or does it have to be added like all the other spacecraft? if so will it be available?

Earth's night side. Atmosphere is glowing not in red color, as expected... I have to tweak the atmospheric scattering code. There is a tail of the comet Encke visible in top left (comets brightness is not calibrated yet)

would the atmosphere also cast orange/red light on objects like spacecraft and the moon when passing behind or does it still just do regular shadows?

Yes, and yes.

No. HDR/autoexposure is not related with lighting, it is just a post-process technique.
