2d images with Graphics3d

Hi, I'm trying to use a 2d overlay for the text in my 3d game. The text engine works really great in my test environment, but when I use the ScaleImage function to account for variable screen resolution WHILE I call Graphics3d, the program flops... black screen. It works great when I use the Graphics function instead of Graphics3d, but I need it to work in graphics3d so that I can run my game. Is there some sort of incompatability between graphics3d and scaleimage? because it only doesn't work if I use both.

Any code to demonstrate whats happening?

ok...

Graphics 640, 480

image = LoadImage("mountainst.jpg")
ScaleImage image, 1.5, 1.5

DrawImage image, 20, 20

While Not KeyHit(1)

Just ScaleImage, Graphics, works. then...

Graphics3D 640, 480

image = LoadImage("mountainst.jpg")

DrawImage image, 20, 20

While Not KeyHit(1)

Graphics3d, no scaleimage, works... but then...

Graphics3D 640, 480

image = LoadImage("mountainst.jpg")
ScaleImage image, 1.5, 1.5

DrawImage image, 20, 20

While Not KeyHit(1)

Graphics3d and ScaleImage used together, black screen. Does that help?

Alright... thanks... but you guys are asnwering everything except the question I asked first. All I want to know is, why does the code snipet not work while the first two snippets do?

This appears to work:

Graphics3D 640, 480

;image = LoadImage("mountainst.jpg")
image = CreateImage(300, 200)
SetBuffer ImageBuffer(image)
Line 0, 0, 300, 200
SetBuffer FrontBuffer()

ScaleImage image, 1.5, 1.5

DrawImage image, 20, 20

Maybe it's defaulting to the backbuffer? Try using a Flip and see what happens.

Yes, Graphics3D sets the active buffer to the back buffer. Just Flip() when you're finished rendering (and drawing) a frame. You'll need to Cls() too if you're not RenderWorld()ing.

That makes sense. thanks.
