Introduction
In this tutorial I will explain how you can create stained glass windows that cast realistic colored shadows.

NOTE: I take for granted that you already know the basic techniques like booling and working with the Materials Lab and the Terrain Editor.




Step 1 - Prepare your image
 
Open your paint program (I am using Photoshop 7) and paint on a new layer the outlines of the pattern. Save the file.


Add the colors (the best way to do this is to put a new layer under the first one) and save the file under a new name.


Write down the size of your image, my image for example is 544 x 768 pixels.


 
Step 2 - Create a wall with a window
 
Open Bryce and use two cubes to bool a wall with a window opening. 


IMPORTANT: The negative cube which creates the opening must be the size of your image; 
in my case I set for x 54.4 and for y 76.8, z can remain as it is.


Don't worry if the wall looks very large at the moment, later on you can scale it down.


 
Step 3 - Insert the glass
 
Press and hold the Ctrl key and click the negative cube. Select it from the list. 



Copy it by pressing Ctrl-C and paste it by pressing Ctrl-V einf�gen. 
This creates a copy of the cube at exact the same position, but it is not part of the boolean group. 


In the Object Attributes box reduce the value for z, for example 0,1 oder 0,2 (see screenshot above). 

Now the cube looks like a thin pane of glass.



 
Step 4 - Apply the glass material
 
Open the Materials Lab. For Transparent Color set your colored image. Set transparency to 100.

Note: The option "Normal" must be selected, because if you use "Blend Transparency" the glass would get invisible!


Higher intensities of Ambience and Diffusion make the glass appear brighter and more luminant. 
These settings depend on your personal taste. You can set Specularity and Reflection to your liking as well.


To test the effect: 
Place a light behind the window or move the sun to light the glass from behind. 
Render. 
Our window looks quite nice already. If you use it for background only it can remain like this. 
But just in case you want to do a close-up we will improve the look of the metal frames which are so typical of Tiffany glass:


 
Step 5 - Add an extra metal frame (1)
 
Duplicate your glass cube (Ctrl-D).


Click on "Edit" and click and hold the small double arrow (see screenshot above) 
and choose the symmetrical lattice from the list. 


Now our cube has turned into a lattice, but it is turned the wrong way. 
We will correct that now:


Open the Object Attributes box. 
Swap the values of y and z and rotate 90� around the x-axis. 
Increase the value for y a little bit, let's say 0,5.







 
Step 6 - Add an extra metal frame (2)
 
Open the Terrain Editor. 


Click on the grid selector and choose 256 or 512 (try what you like best!).



Load the image with the contours (Rose1).



Click on "Invert". 


Click once or twice on "Smoothing" to soften the edges.


Click on the OK sign to close the editor.


Now apply some material to the terrain, for example silver or gold.







Of course you can also create framings of wood or stone. Use your imagination, be creative!

Have fun,
esha

Introduction
Here is a tutorial for those of you who charish the beauty of stained glass. So many windows throughout history have been pinicals of the world of art and religion. The art of stained Glass, is one of harmony with light. This tutorial is dedicated to those magnificent artists who have brought so much beauty into this world using those little shards of glass.


Step 1 - Finding and Using the Right Image
 
The correct way to find and utilize a religious stained glass window is to ask the church minister if you may photograph the window, and then leave a donation to the church. You will find doing this is much more rewarding.
 
Step 2 - Monochrome Jpeg Image
 
You will need an image of a stained glass window, or similar image you created yourself. Open the image in your favorite Art program (I used Photo Impact 6.0), and change the image to black and white (Monochrome).
 
Step 3 - Invert Monochrome Jpeg Image
 
Once Monochrome, Invert the Image so that it is like a photo negative, then save as a transparency�. Placing the word Trans in the name usually does the trick.
 
Step 4 - Create 2D Surface
 
In Bryce, Select the 2D object. Select the square or circle depending on the shape of the window being created. Then size it to the shape and size similar to the image. This can be done after the images are applied to fine tune the window.
 
Step 5 - Apply Jpeg Image to 2D Surface
 
Click on the 2D object, and press the (M) materials editor. Select Diffuse, and Ambient in both places as shone above. Select the "Image Texture button", and then the "Texture Source Editor" button. Select an empty box at the bottom and load the desired Image.
 
Step 6 - Apply Invert Monochrome Jpeg Image as Transparency (Optional)
 
Select Transparency from column B, and the select "Image Texture" button, and then the "Texture Source Editor" button as before. Select an empty box at the bottom and load Monochrome Jpeg Image. 







Then Select Copy from the first window and Paste to the second window.
 
Step 7 - Adjust settings to achieve the desired look
 
Make Adjustments to your settings as needed. Transparency may remain at zero. This still gives a slightly transparent look. The higher the transparency the more diminished the color and detail. Raising the Ambience will increase the color, and create the illusion of light on the other side of the window. Bump Maps may be added, but should only be considard for extream close-ups.
