bone hierarchy transformation problem
Tue, 11 Nov 2008 21:21:20 -0800 (PST)
I've almost cracked rigid mesh animation, I have got a helicopter with
tail & main rotors spinning, landing gear moving up & down, and cannon
rotation on the x and y axis. Each of those groups are linked to a
single joint which is rotated to give me the animation. All good so
far.
However, if I setup two jo ...

World, View: oddities

Hi again,
in my painful porting from OpenGL to DX I have to face a last
obstacle, at least the last *basic* obstacle before I move on to the
engine itself..
I am trying to make a first person camera work, without using
D3DXMatrixLookAtLH.
I've got a few meshes on screen, each one with its World
transfor ...

smoothing a cone
Fri, 7 Nov 2008 10:53:59 +1030
This isn't exactly a DX problem but I thought I would present it here
regardless.
I have written an algorithm to smooth meshes and came up with a glitch that
can be best represented by a cone.
First I iterate through the triangles in the cone, then iterate through the
vertices in each triangle.
At each verte ...

Driver version reported by DXDIAG
Thu, 6 Nov 2008 09:47:56 -0800 (PST)
Hello,
how do I get to the display driver version (like 7.15.0011.6926)
reported by DXDiag programmatically? I need it to identify buggy
drivers and disable hardware rendering for them. I already use
EnumDisplayDevices to get the PCI vendor ID and some other
information.
TIA,

Hi again,
thanks everyone for clearing up my mind on many DX levels. Your help
has been really valuable, so here I am to inquire you about my first
doubt after I actively went into D3D9 coding.
So, to use DrawIndexedPrimitives I created my custom vertex type, a
vertex buffer, and index buffer, and so on. ...

DirecX8.1 beginners steps - The model gets cut off when camera goes up
Mon, 3 Nov 2008 17:37:05 +0100
Hello all,
I've got a simple setup with a single model in it and a camera which
currently can only move over the three axis.
When I move the camera up (using D3DTS_VIEW, incrementing its Z coordinate)
the displayed model seems to loose parts at the far end. Its like the model
gets dipped into water which ...
