Background Images
« on: August 01, 2010, 10:58:06 am »

      Is it possible to import your own background images ?   
      The way I understand it is, that background images are .bmp files.
      I'm just not sure what size they should be ?
          I have some pics that I edited with Photoshop.
          I was looking through the Turbo forum archives, but I didn't see any topics
      on it.   Unless, I didn 't look hard enough.

Hi Garystan
Yes you can use your own backgrounds, the size can you get if you browse trough the textures in TFP, you can also use a bluescreen as the do in movies and replace it after rendering with a background image, as I have done in this post http://forums.turbofloorplan.com/index.php/topic,1149.msg5551.html#msg5551

Yes as noted above.

Another alternative is to insert a very large mirror (re-size to like 50' x 100' for example) and apply an image to it.

Why?  Instead of replacing bkgnd via Photoshop (which is OK and controlled), you can align the mirror picture to your desire to get the view you want....especially good for looking out windows from inside camera view to see outside...otherwise you may have to rotate your whole house to align the window to the bkgnd....or else in Photoshop center the image so it shows like you want it in your scene. 

If the bkgnd is all trees (for example) and a particular tree is not important for placement, then easiest to load a picture to the background image files and use it directly.

If you want to see a lake view a certain way, then easiest to use a mirror with a picture applied,rather than a mirror surface.

Like any image you use, image resolution (pixel x pixel) may be important if picture detail is important....so its not blurry or pixelated. Compare your render (1024x768 for example) and if the picture import fills 1/2 of the render, then 800x600 for the picture is probably safe....but 256x256 may not be OK)

Hi Garystan,

As you can see there are many options - I have yet another:

Photoboards
Import the image directly as a Photoboard (File/ Import/ Photoboard Wizard).  This does not require inserting into anything, it just becomes a freestanding image you can move into position behind your model and resize, elevate  etc. It has the advantage that you can position the exact scene behind your model, but, as with Doug's idea of putting the image into a mirror, you will have to be careful that the sun illuminates it correctly and it does not cast a shadow on your model. 

Several photoboards are used in the office image in this post http://forums.turbofloorplan.com/index.php/topic,758.0.html as the background and to provide the refection in the windows.  The proper TFP Background image will not reflect in your model, so if you want the ouside to reflect in a shiny floor for example, you have to use a photoboard or separate image, outside the window or door.

Once you import the image as a photobaord, it is just in a placeholder in your model. If you want to use it again, you can add it to your catalogue using File/ Catalogues / Save Element to Catalogue. You will then be able to use it again with File/ Insert / Photoboard). If you alter the original image on your computer (eg make it darker or lighter) it will change in your model. If you delete it, move it or rename it or the folder, it will dissappear from the model and catalogue and just leave a grey placeholder.  Such images are best saved in the TFP Textures folder so you do not accidentally lose them.

The image does not have to be a BMP (JPG is fine) as long as you do not want to cut out any part of it to make it transparent (as in cutting out the background of a photo of a tree so you can use the tree in your model).  This must be a BMP and the background colour or transparent part, set to Magenta (Red 255, Green 0, Blue 255). In this post http://forums.turbofloorplan.com/index.php/topic,771.0.html the background photoboard has the carport cut out to show plants behind and landscape inserted in front of it to create the garden. Most of the plants in the garden are also photoboard cut outs.  The image below shows the Photobord image of the house (with carport cut out) and the photoboard trees and plants (from this angle they look 'flat'). If you used a photoboard (or Doug's mirror option) basically you can only render from the exact angle to that shows the photoboard filling the camera view, as in the third image.

The image size for a photoboard does not matter either, as long as it is a clear sharp image, as it just sits on your computer and is linked to TFP. If it is not big enough, just right click, select Properties and resize it and use elevate to move it up or down so that the horizon on the image aligns with your terrain.

The above options are to get a specific view behind a specific angle of your model (eg the scene at the back of the house when looking from the front).

Backgrounds
If you just want to use a scene that you like, instead of the existing ones, you can just add an image to the Backgrounds as Robert mentioned, in the same way as you add a new texture.  The only problem with the Background image is that you cannot control its position - it just floats around your model, so every side has the same view. You cannot change the brightness or raise or lower it or resize it unless you do that to the original file on your computer. The image will work best if the horizon is vertically in the middle of the image.

One added thing you might do...if desired....to make a final result look more like a photograph...

either:

- make the background slightly out of focus (blurred) or blurred at farther distances

- use Photoshop or similar to do slight foreground and background blur to aid in depth of field limitations "look"

But don't over do it to be obvious....deception is the key...make it look like photo....not better or worse.
