Hi
shurely i'm doing something wrong, but, i can't make the Draw commands of FastImage (DrawLine for example) in conjunction with shadows. Following is a code in that the problems appear:


Graphics3D 800,600,0,2
Include "fastExt\FastExt.bb"
Include "fastExt\ShadowsSimple.bb"
Include "fastExt\FastImage.bb"

InitExt
InitDraw 

CreateShadow  1
ShadowRange  50
ShadowPower   0.5
ShadowColor 180, 200, 255
ShadowTexture = ShadowTexture()
LightPiv = CreatePivot()
PositionEntity LightPiv,0,20,0
ShadowLight = LightPiv

cube1 = CreateCube()
EntityColor cube1,0,0,255
PositionEntity cube1,-4,0,0

cube2 = CreateCube()
EntityColor cube2,0,255,0
PositionEntity cube2,+4,0,0

piv = CreatePivot()
EntityParent cube1,piv
EntityParent cube2,piv


cam = CreateCamera()

light = CreateLight()

PositionEntity light,-5,10,-5
PointEntity light,piv

PositionEntity cam,0,5,-5
PointEntity cam,piv

CreateShadowCaster cube2

;shurely i'm doing something wrong or ommiting shomething,
; seems that the Draw functions of FastImage And the shadow systems interfere.
;
;if i don't apply the shadow texture, then DrawLine works ok
;if i apply the texture, DrawLine stop working
;is there a way to have the shadow applied and the Draw functions of FastImage both working on the same code?

SetBuffer BackBuffer()


While Not KeyHit(1)

	If KeyHit(57) Then	;press space to make cube1 receive shadows, and DrawLine stop drawing
		EntityTexture cube1,ShadowTexture,0,2
	End If
	
	UpdateShadows cam
	
	TurnEntity piv,0,0,.1
	
	RenderWorld
	
	StartDraw
	
		SetColor 255,255,0
		ProjectObject(cam,cube1)
		x=ProjectedX()
		y=ProjectedY()
		ProjectObject(cam,piv)
		DrawLine x,y,ProjectedX(),ProjectedY()
		
		SetColor 255,0,0
		ProjectObject(cam,cube2)
		x=ProjectedX()
		y=ProjectedY()
		ProjectObject(cam,piv)
		DrawLine x,y,ProjectedX(),ProjectedY()

	EndDraw
	
	Flip False
	
Wend

FreeShadows
DeInitExt
DeinitDraw


Function ProjectObject(cam,obj)

	CameraProject cam,EntityX(obj,True),EntityY(obj,True),EntityZ(obj,True)

End Function

I'm trying to use shadow in a worl editor i'm making to help placement of the newly created objets or when moving, rotating and the like some objets, And using Draw comands to superimpose axis, bounding boxes over the selected ones and the like, but, when i started to use FastLib to speed the Line functions of blitz, all started to work wrongly, and after some debbugin i found that when i apply a least one shadow texture, the draw commands of fastimage fail.

in the code above, when "space key" is pressed, the shadow texture is applied and the drawn lines between the boxes stop drawing.

some ideas??

thank's

thank's for try

i use:

FastExt 1_15
FastImage 1_73
FastText 1_24
Blitz 1.98

Mobile Intel GMA 4500M

i have to think that the problem is some incompatibility wiht my video card?

i was using blitz 1.101 but the documentation in FastImage recomends blitz 1.98, 1.99, so i do a downgrade of blitz, but the problem still persist on my machine.

i don't belibe that appling a texture makes stop the drawing of FastLib

i reposted on the FastLib thread, mikailv say or confirm my theory that the problem is with my video card, yes a cheap one (intel mobile)
