As this is still in early development and like a moving target, please always specify the hash-code of the version you use. It helps developers tremendously to nail down a bug.

Don't bother to mention the download site or the dot-version (0.1.x.charlybrown), as it is no real identification. Just give the hash-code - the first 6 characters should suffice already.

Yes. I intend to use 3 types of microtextures: normal, displacement and diffuse. Diffuse and normal will be DXT1 images and will affect color and surface normal of terrain while displacement will be a grayscale and will actually decrease/increase elevation. also, it should be possible to use different microtextures for flat and coarse terrain, so mountains will have one microtexture and valleys will have other (coefficients for them can depend on angle between sphere normal and terrain normal). Displacement microtextures will give better result with FL11 because it can add necessary mesh resolution by HS/tesselator/DS stage without significant performance drop while in the case of FL10 there's no hardware tesselator (CS 4.0 approach will probably have bad performance) and therefore I will just use 2 times better resolution of tile mesh in that case (32x32 instead of 16x16).

Well just by looking at the screenshot I can tell you it isn't latest version. You can get the latest one here: https://bitbucket.org/asmi/ovp Remember it requires Orbiter 111105 beta to work.

I doubt that this is the right hash-code. It points to the topmost of the mirrored changesets of Martin's SVN repo, not containing a D3D11Client at all. In fact, that changeset doesn't even contain binaries. See here: https://bitbucket.org/asmi/ovp/src/fb4e78fc7439 . Note the hash-code at the end of the URL.

If you want asmi's newest client, use the following link to immediately get the newest ZIP archive: http://bitbucket.org/asmi/ovp/get/D3D11Client.zip

Seeing as this question keeps coming up there should proably be a stickied post with a "get latest version here..." and download/install instructions.

There is one - link is in my signature. This link goes to "sticky" thread that does have all instructions... So it looks like the issue is not the absence of information...

Oops missed that, I've been reading this thread without paying much attention to the sigs

Hi,

What kind of normal map formats are currently supported by D3D11 or will be supported into the future ?
Which ones are more recommended and which ones are less recommended for use ?

Hi,
vessel normal maps: D3D11 uses 3 or 4(in that case 4th component does nothing) component textures as normal maps. Normal maps loading was implemented by D3DX11GetImageInfoFromFile + D3DX11CreateShaderResourceViewFromFile functions, so format of texture will be the format read by D3DX11GetImageInfoFromFile. More recomended file format is DXT1(because of its good compression), but DXT3, DXT5, R8G8B8 or R8G8B8A8 will work as well. 2-component normal maps (where 3rd component is computed in pixel shader) currently not supported, but it can be added in future if it will be needed.

planetary normal maps: DXT1 256x256 tiles, file format is .tex/_tile.bin/_tile.tex file format currently used by Orbiter for planet textures (so, normal maps can be created by pltex without any new tools). I don't think planetary normal map format will be changed in future.

What about eclipse shadows? Is there any progress concerning this feature in one of the clients?

It is doable, however currently I don't have it in my short-term plans.

Guys, I've got some great news - it looks like new DGIV version soon will be available, which will work with D3D11 client! After some fixes inside client, latest beta from Dan seems to be working just fine. Here is what it looks like:

DGIV on Moon orbit:


DGIV's ascent autopilot at work:

[SolarLiner]

Good to see this ! I've just finish to download DX11 and I test.

[asmi]

I've just uploaded a new build with fix for "103% issue". Also - if some you guys have got some spare time - please help Dan (and me) with DGIV testing by joining his beta testers program. You can do so by leaving a post here: http://orbiter.dansteph.com/forum/re...=15083&t=15083

Thanks in advance to anyone who will help us make the combination DGIV + D3D11Client working and bug-free!

[asmi]

Update - I've fixed some nasty bugs. That should improve compatibility with vessel addons (for example now Soyuz FG/U seem to work fine, while previously it CTDed at T-13, and there were animation issues too starting from service tower separation).
In addition to it in the background I'm trying to come up with lighting model that would allow to implement beacons' shadows and terrain self-shadowing without trashing performance...

Just been doing some more unstructured testing (don't get time to do any serious stuff). I still have problems with surface tiles:





and my issue with the KSC tiles remains in the latest version:


(I know this is an older version but the problem remains in the Mar 21 build)

I'm beginning to think it may be to do with my hardware/drivers (mobile I3/HD 3000). I know Intel aren't renowned for their OpenGL drivers, and I've been messing with driver versions to try to find a decent one that doesn't hobble Google Earth in OpenGL (latest driver kills framerate to 0.2fps from 45) and Celestia (fps c.5) but also works with Orbiter d3D graphics clients. Some driver versions appear worse than others in D3D11 client for producing weird tile effects.

A final issue (not sure if it's related) I get texture not loaded warnings for *_n textures which do not exist:
