these changes have to be done in one of the java files in the vrml97.jar file, right? but when I open the jar file with winzip I only have the class files, where can I find the vrml97 open source file?
Am I right? question from a newbie :( -----Original Message----- From: Juergen Neubauer [mailto:[EMAIL PROTECTED]] Sent: Thursday, October 25, 2001 12:38 To: [EMAIL PROTECTED] Subject: [JAVA3D] Java3D VRML Loader (vrml97.jar) gzip files Hello ! Just in case somebody still uses the old code from SUN and tries to load big (>1MB) gzip vrml files, I have a hint: (all following is in the package com.sun.j3d.loaders.vrml97.impl) Loader.java reads the incomming file byte by byte and there is a call to ByteBuf.java. To speed things up, one could simply increase the value for that buffer (ie: from 1024 to 65536). Another way is to add a line after "gis = new GZIPInputStream(is);" (line 315) which simply assigns the GZIPInput Stream gis to the InputStream is. - > "is = gis;" Then comment out the lines from "ByteBuf bb = new ByteBuf();" till "is.reset();" - altogether 14 lines of code. Doing this 2 changes bypasses the call to ByteBuf.java and reads a 3MB file in 14 seconds (instead of 11 Minutes). If anybody has a reason why the call of ByteBuf is necessary, tell me please. If anybody needs additional hints or needs the "patched" vrml97.jar, feel free to contact me. -Juergen. =========================================================================== To unsubscribe, send email to [EMAIL PROTECTED] and include in the body of the message "signoff JAVA3D-INTEREST".
