Mars in DirectX 10

Post #1by Fightspit » 25.03.2007, 12:27

Nvidia provides some code samples for Geforce 8x00 series (compatible Dx10):

Here one of them about Clipmaps,

Clipmaps are a feature first implemented on SGI workstations that allow mapping extremely high resolution textures to terrains. The original SGI implementation required highly specialized, custom hardware. The advanced features of the NVIDIA?® GeForce?® 8800 now permit the same algorithm using consumer hardware.

Fightspit,

It doesn't matter what version of Direct X you have installed or are using. Celestia doesn't use the Direct X APIs so there will be no benifit using DX10 over DX9. You need to get your facts straight. So saying that the image above is Celestia in DX10 is totaly in accurate as its Celestia OpenGL.

So while this info is interesting it has nothing to do with Celestia until there is a port of it to Direct X.

Don.

Fightspit never said anything about it being Celestia. That's a screenshot from a small program from nVidia.

What's the point? My own Mars textures look definitely better and are higher resolution. I don't need a geforce 8 for this.

While that mars image does look nice it is off topic since its not taken in celestia. IMO Direct X 10 is not worth getting Vista for. The only card that supports it so far is the GF-8800 that i am aware of. So far everyone that i know that runs Vista has nothing good to say about it. Most have rolled back to WinXP due to the sheer resource hog that Vista is. I will wait a couple of service packs, and a new computer with a quad core cpu, and at least 4 gigs of ram before i try it out.
