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 booleaning and working with the Materials Lab and the Terrain Editor.
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.
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.
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.
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.
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:
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.
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!
