Auto-clip Lamp Buffer Setting a good range for clipping start/end for Lamp buffers is important for good quality shadow (depth details). That can be quite a hassle, when many lamps or animated objects are involved. This option allows to have the clipping range calculated based on the visible vertices in the spotbundle. For clip start and clip end it can be set individually. Typically the clip start defines quality most. The shadow buffer 'bias' value is corrected for this automatic clipping too, to ensure that ranges that differ give same biasing appearance. (If this wasn't done, you would see lighted areas become darker or lighter, or even artefacts, when the range changes suddenly NOTE: since it only checks for vertices, be aware that large planes can give errors. Implementation note: zbuffer values are non-linear (1/z) because that allows linear interpolation while filling scanlines. That's the main reason for the precision to be highest close to the eye (or lamp). It's even a useful feature, since you want details to be precise when they're closeby. Since these values are also in the -1 to 1 range, using floats here wouldn't solve problems a lot. Maybe trying a 64 bits Z once might be an interesting coding job. |

Welcome to the fun world of open source. For instructions on building and installing Blender, please see the file named INSTALL. ---------------------.Blanguages and the .blender directory--------------------- The .blender directory holds various data files for Blender. In the 2.28a release those are the .Blanguages file containing a list of translations, the translations themselves and a default ttf font. Blender checks for the presence of this directory in several locations: - the current directory - your home directory - On OSX, the blender bundle is also checked - On Windows, the installation dir is checked. If you get a 'File ".Blanguages" not found' warning, try to copy the .blender dir to one of these locations (your home directory being recommended). -------------------------------------Links-------------------------------------- Getting Involved: http://www.blender.org/docs/get_involved.html Community: http://www.blender3d.org/Community/ Main blender development site: http://www.blender.org/ The Blender project homepage: http://projects.blender.org/projects/bf-blender/ Documentation: http://www.blender.org/modules.php?op=modload&name=documentation&file=index Bug tracker: http://projects.blender.org/tracker/?atid=125&group_id=9&func=browse Feature request tracker: http://projects.blender.org/tracker/?atid=128&group_id=9&func=browse
