Image Description, by matthew



A few pics generated by the "Quantahawk" engine I've put together. It is meant to be a versatile tool to rapidly generate real time environments.

You can browse for models and scripts at run time. So far it can set up the following by script:
  • Load X file mesh models
  • Initial alteration of world space scale and location.
  • Hierachical position and orientation of mesh objects.
  • Real time dynamic shadows.
  • Point sprite particle systems.
  • Vertex tweening mesh.
  • Alpha sorted axis and full billboarded Quads.
  • Pre and Post render states for individual geometry.
  • ray-mesh collision detection.
  • Script driven programmable dynamic orientation
  • Simple "Perlin Noise" terrain generation
  • Spherical environment mapping for quasi-reflective surfaces
  • Electricity effects.
  • Set center of gravity
  • Replace xfile textures with others
  • Fog
  • Gravity, collsion detection, Keyboard& mouse navigation modes can be toggled at run time. Lighting can be altered at run time. There is the beginnings of a user interface that uses quads in camera space with ray-mesh collision detection for buttons. Although there is not many sound effects at the moment you can apply FX like echo, distortion and reverb to wavs.

    You can get an .exe and some media from my web site www.labyrinth.net.au/~mstephens

    I would be happy to discuss any ideas with like minded individuals.

    i'm sure it would look beautiful if the image actually loaded fully (something with flipcode and konqueror), i didn't know labryinth was still open, great to see aussie work :)

    i totally love those objects in the shot above the bottom right one! :) how'd you make those?

    impressive engine...

    Diese Abbildungen geben mir ein steifes.

    oho, da kann ja eines hochdeutsch schreiben. oder auch nicht.. :)
    es heisst einEN steifeN, nicht ein steifes.
    und steifen wäre auch noch gross geschrieben.
    ERGEBNIS:
    Diese Abbildungen geben mir einen Steifen.

    oder schöner:
    Diese Abbildungen erregen mich zutiefst..

    ich frag mich nur weshalb.. :)

    schönen tag noch

    for all the non-german-readers, dirty south african is really a dirty guy, talkin about sexual feeling in these pics. i don't want to go more near into this topic.. possibly there are non-adult people willing to read this, too:)

    "Diese Abbildungen geben mir einen Steifen. "

    Naja, ob das so richtiger ist? "Von diesen Abbildungen bekomme ich einen Steifen" klingt besser...

    What's with the German stuff all of a sudden? :)

    Anyway, very cool looking IOTD! And an even more impressive feature list.

    WoW!
    I too like the objects in the show above the bottom right one. Really awesome.

    Wobei man sich jetzt natuerlich wieder streiten kann ob die Pixel zusammenhaengend eine einzige Abbildung ergeben, oder das es doch fuer sich genommen mehrere Abbildungen sind...

    That looks so awesome. The house looks great, and the abstract shapes are just plain cool :)

    Hallo, ich bin aus Dänemark! Das Bild ist toll! (is this right? ;)

    Cool! I especially like the upper two images, and the one above the lower right one...

    Vielleicht meinte er ja auch, dass ihm das Bild ein halbgefrorenes Bier anbietet?

    It's a closed spline shape "lofted" along another spline. The shape is scaled and twisted along the loft aswell.

    Seg faults on my Win2k machine inside D3D immediately after the window comes up. I have DX 8.1/GeForce3

    I'll get my merry band of testors on that right away

    crashes on my machine, too (W2K, DX8.1, GF2)
    It seems that it was tried to read from a nullpointer.

    Looks great except in the bottom left picture (the gears) I think those are the edges of the skybox I'm seeing there. Other than that looks awesome! Keep up the good work!

    It's odd that there's been failure on these systems Win2000, GF2, DX8.1 as they are similar to mine.
    Unfortunately the downloadable version does fail when:
    The shadows have set to TRUE in the ..scriptinitial.txt file, minimum stencil bits is not 0 and you run it with a video card that does not have stencil buffer CAPS.
    But the NVIDIA ~V7100 chips in the GF2 and up do have stencil buffer capacity...
    If you alter the text file (remembering to leave some white space between strings) hopefully it will run OK but without shadows and tweening. There is some mention of this in the brief documentation.

    Real time dynamic shadows

    what shadowing method do you use?

    very nice images :)

    Dear Captain Qirk,
    I just used the standard stencil buffer technique which was very well described by D3DX 8.1 volume shadow example you get with the SDK. (OpenGL probably also has this technique well documented).
    I made a couple of C++ objects. One makes the shadows the other has a nice STL vector (one of Stroustrup's nifty dynamic arrays) of the shadow volumes and a big grey quad. You can get these shadowy objects off my web site.

    Well spotted, I must remember to clamp them or something.
    Some may recognise the skybox textures from an OpenGL sample. All my texture artists are run of their feet. And a good skybox is hard to come by.

     
    Morgan

    March 19, 2002, 12:42 AM

    Nope, I turned off shadows and stencil bits and it still crashes immediately.
