<0> since the multiply them together...
<1> yes, they multiply together
<1> to make your GL matrix
<1> but there is no element of cursor position
<1> from the camera view
<1> or whatever view
<0> do you have a matrix that stores the rotation and position of your camera?
<1> regardless, no mouse pos being calculated in there
<0> yes it is
<0> v!
<1> but it doesnt use V
<1> vPickRayOrig.x = m._41;
<1> it uses only m
<1> and m is just world*view
<1> you agree?
<0> just do the first stuff and get v
<0> discard the other stuff
<1> i Got v
<0> now, do you have the rotation and position of the camera?
<1> yes
<0> get the inverse of that
<1> which is m
<1> got it
<0> call it cameraToWorld
<0> ;)
<1> Matrix camToWorld = matWorld * matView;
<1> there
<0> no
<0> camToWorld = worldToCam.inverse();
<0> worldToCam = rotation and translation of camera
<1> Matrix m = matView;
<1> m.Invert();
<1> renamed m to camToWorld
<0> Now theres two different ways of doing this
<0> rayStart = Camera.position; rayDir = normalize( cameraToWorld * v - rayStart ); ( I think )
<0> rayStart = cameraToWorld * v; rayDir = camera.rotation.getZAxis();
<1> and where does mouse position come into that
<0> v!!!
<1> ah
<1> i typed it out
<1> i mean nm
<1> which one?
<0> ?
<1> your 2nd line?
<0> use whichever you like the most ;)
<0> try both
<1> both awkward
<1> i dont have cam position or rotation seperate like that
<1> you awkward so and so
<1> ;P
<1> cant multiply a matrix by a vector
<1> f******
<0> why not?
<1> no operator :(
<1> hehe, ready for giving up
<1> 2 hours now nearly
<1> on picking...
<0> so use a regular function?
<1> like friggin what?
<0> what matrix and vector code are you using?
<1> D3DX
<0> so you're telling med the C# version of D3DX doesnt have a Matrix4x4 * Vector3 transformation function?
<1> yep
<0> then you probably havent looked hard enough...
<1> ErrorOperator '*' cannot be applied to operands of type 'Microsoft.DirectX.Matrix' and 'Microsoft.DirectX.Vector3'C:\Documents and Settings\Admin\My Documents\Visual Studio 2005\Projects\LevelEditor\LevelEditor\FrmMain.csLevelEditor
<0> so you base all that on that error message?
<0> have you bothered looking in the docs?
<1> you mean the half written ones?
<1> yes i have
<2> yeah, what swx said
<2> and allow me to add, newb
<0> so write your own function? :P
<1> vPickRayOrig = Vector3.Transform(v, camToWorld);
<1> there
<3> yo
<3> since i got my blackberry
<3> i wanted to learn wml
<1> returns a Vector3 though
<3> so i give you
<1> Vector4 i mean
<3> http://wap.sleazysoft.com
<3> for wireless devices
<0> so ignore .w
<1> cant the way im using operators all down my code
<1> but
<1> nope, doesnt work either
<4> yoyo dog
<4> w***w*** w***sup
<1> om
<1> it works
<1> wtf did i just change
<1> Rendering.device.Transform.World = Matrix.Identity;
<1> when i draw the line
<0> :P
<1> but
<1> the ray looks weird
<1> yet its placing my ship correctly
<1> directly under the mouse
<1> the origin doesnt look like its directly on the mouse pointer
<1> but its casting in the right direction
<0> which one did you use?
<1> what could cause that
<0> the first or second?
<1> ive done..
<0> or the original one?
<1> Vector4 temp = Vector3.Transform(v, camToWorld);
<1> then chopped off the w
<1> i dont see how this can work
<1> hehe
<1> doesnt look its working properly
<1> but the results are what i want
<1> maybe i should just move on :P
<0> :P
<0> are you sure its working properly?
<0> your naming seems to be wrong...
<0> v is in camera space
<0> nm
<0> its correct
<1> wanna see a screenie?
<2> no
<5> hehe
<5> lol
<6> anybody good with trig?
<7> shouldnt you be
<1> heh
<1> how far with Trig
<6> Anyone familiar with half-angle identities?

<9> *cough*
<9> why would you do that?
<10> huh?
<2> it was alaskaby
<9> aren't you norwegian too? :)
<10> yes
<2> well true
<2> busted
<10> oki
<9> welp
<9> if you had a hand in the flood, u ****.
<9> otherwise, no worries :)
<11> pretty pointless flood at that
<10> I didn't have anything to do with it but i knew it was coming. I know the whacko who did it.
<11> so what does JEG_VIL_H do anyways
<11> Ghaleon is a IRL gamedev ;D
