"Retired" teaching professor of CS at Carnegie Mellon but still teaching because Golan Levin showed me Processing six years ago -- great tool for a first time exposure to programming.
I have been teaching with Processing for about 6 years. I just moved to 2.0 (for admin reasons) and an not up to date on the forum discussions for 2.0 - apologies in advance is the answer is out there. The cluster in which I teach is running Windows 7 on 2 year old machines. I use a Mac portable. Yesterday we explored 3-D and the Windows machines too a very long time to begin executing the program when either renderer is in the argument list for size( ) or the program fails to launch. There are no visible error messages. My Mac portable shows no such lag. Is this a known problem for Wndows or specifically Wndows 7? Does anyone have a suggestion for the SysAdm folks that might fix this?
Thanks. Jim
I am teaching an intro programming class for Carnegie Mellon's College of Fine Arts. I have been working with and teaching with Processing for about six years and am still learning new stuff from my students' work with the language and its API.
In response to several questions on texture mapping, I did a search and found some very nice code mapping an image onto a sphere. This was posted in the then current forum on May 26, 2010 by an author named yellowcap. I want to cite the author in the material I present to my class and post on the course web page. Can anyone give me a link to this person so I can do a better citation than yellowcap and the date?
I realize this is not really a programming question but it seemed like the best place to ask the question.
I am teaching a first course to about 100 students. Each assignment requires an applet posted to a portfolio web page. The current assignment requires the use of either P3D or OPENGL. Both run properly in the IDE but the applets fail to load for OPENGL. I tried this as an applet on the web and using appletview on a Mac in the terminal window. The first part of the error message is:
FRED2:applet7 jar$ appletviewer index.html
java.security.AccessControlException: access denied (java.net.SocketPermission download.java.net
connect,accept,resolve)
at java.security.AccessControlContext.checkPermission(AccessControlContext.java:264)
When I removed the import statement for OPENGL and replace OPENGL argument in the function call of size( ) with P3D, the error goes away.
I am assuming the import is the problem.
Two questions:
briefly, why?
Is there a work-around to allow for import of this or other libraries that I want the class to use in future assignments while continuing to post applets on the web.
I am teaching with the Processing IDE. I have a student who is color blind. I have tried to alter the colors in the IDE in the past by shutting down Processing and editing the preference document in the appropriate places. My edits were ignored. I know I am editing the active preference file because the font info changes when I alter the font size. Using the current version, I see that the lines in the preference file relating to colors in the IDE text are no longer there.
