Last Update: July 2009

Selected portions of the book, PROCESSES IN BIOLOGICAL VISION are available here for downloading and review. The author would appreciate any comments concerning this material. If the reader has a specific interest in a portion not yet available, please send a comment to that effect and arrangements can be made.

Because of inquiries, a Beta-release CD-ROM has been prepared of the entire text, PROCESSES IN BIOLOGICAL VISION (2400 pages, ~800 figures, ~1000 references). The most recent CD-ROM is dated 1 June 09 and represents a significant update over the material on the site. Also, a 190 page tutorial, BIOLOGICAL VISION: A 21ST CENTURY TUTORIAL, has recently been published that summarizes the material. It is ideal as a study guide to the complete text and is available for $25 USD by clicking here. A special offer is available for both the Tutorial and the CDROM in the VISION CONCEPTS STORE .

The following files are made available for downloading in .PDF (portable document format)for two reasons:

You must have an Acrobat Reader installed on your system to read or print out these files.

Beta-release CD-ROM is available

Because of the size of some of the above files, some readers may not be able to download the material efficiently from the website. In addition, the current draft of the text has become encyclopedic. It contains a large amount of material in color and many discussions on specific topics that may not be included in the printed text when released.

In response to requests to solve the above problems, a Beta-release version of the complete text (2400 pages, ~800 figures, ~1000 references) has been prepared, in PDF format. It is available in the VISION CONCEPTS Store.
