Hi all, I have a problem with Vector3.Unproject, but i would like to know
what's the best way of calculate space coords if I'm using multiple views.
When i was using just one view, to calculate space coords was very simple.
v3Position.Unproject(device.Viewport, device.Transform.Projection, device.Transform.View, Matrix.Identity)
But now I have two views (of different size) using
device = New Device(Manager.Adapters.Default.Adapter, DeviceType.Hardware, _
handle, createFlags, parametros)
dev2 = New SwapChain(device, parametros)
surface0 = device.GetBackBuffer(0, 0, BackBufferType.Mono)
surface1 = dev2.GetBackBuffer(0, BackBufferType.Mono)
To render I never calculate the device.viewport for each picturebox, but it draws well
The problem its that I get wrong coords and I think this it's cause
I need to store somewhere the parameters of unproject for the two views.
Public Structure dataP
Dim viewPort As Viewport
Dim projection As Matrix
Dim view As Matrix
End Structure
Dim XY_Plane, ZX_Plane as dataP
In render
Select Case tipoVista
Case Plano.XY
XY_Plane.view = Matrix.LookAtRH(eye, dest_eye, vector_up)
Device.Transform.View = XY_Plane.view
XY_Plane.projection = Matrix.OrthoRH(PictureBox.Width / zoom, PictureBox.Height / zoom, 1, 300)
Device.Transform.Projection = XY_Plane.projection
Case Plano.ZX
ZX_Plane.view = Matrix.LookAtRH(eye, dest_eye, vector_up)
Device.Transform.View = ZX_Plane.view
ZX_Plane.projection = Matrix.OrthoRH(PictureBox.Width / zoom, PictureBox.Height / zoom, 1, 300)
Device.Transform.Projection = ZX_Plane.projection
End Select
then in the function to getCoords()
Dim v3Position As Vector3
Select Case tipoVista
Case Plano.XY
v3Position = New Vector3(cX, cY, 0)
v3Position.Unproject(XY_Plane.viewPort, XY_Plane.projection, XY_Plane.view, Matrix.Identity)
v3Position.X = Math.Round(CDec(v3Position.X), 2)
v3Position.Y = Math.Round(CDec(v3Position.Y), 2)
Case Plano.ZX
v3Position = New Vector3(cX, cY, 0)
v3Position.Unproject(ZX_Plane.viewPort, ZX_Plane.projection, ZX_Plane.view, Matrix.Identity)
v3Position.X = Math.Round(CDec(v3Position.X), 2)
v3Position.Y = Math.Round(CDec(v3Position.Z), 2)
End Select
Return v3Position
(I set the viewport for each picturebox in the begginnig of the program)
but still getting wrong coords :(
any suggestions? [dead]
thanks in advance
