Hey, great! Your patch looks good and I've committed it to our sources. Transparency support should be in tonight's daily build. Thanks! --Eric Eric Pettersen UCSF Computer Graphics Lab http://www.cgl.ucsf.edu On Dec 9, 2008, at 9:12 AM, David A. C. Beck wrote:
I've been doing a lot of analysis rendering over proteins in Chimera lately. Bild (via VRML) has worked quite well for this. I wanted the ability to specify a transparency value (from 0 to 1) for the shape objects (boxes, arrows, etc.). The attached patch 'bld2vrml.diff' adds a .transparency 'command' to the bild format that sets the 'transparency' attribute on subsequent objects' 'Material' element in the generated VRML. A sample input file 'test.bild' (see below) and image 'test.png' are also attached.
Example input below: .color green .transparency 0.0 .box 5 5 5 10 10 10 .transparency 0.25 .box 0 0 0 5 5 5 .transparency 0.5 .box -5 -5 -5 0 0 0 .transparency 0.75 .box -5 -5 -5 -10 -10 -10 .transparency 0.9 .box -10 -10 -10 -15 -15 -15
