Does not include the size command with the 3d rendering engine specified, without the 3d engine specified spotlight does not work 2. The first line of the example is the number 1000, this obviously will not compile 3. Uses an undefined variable, which again causes a compilation error Here is the cleaned up code which matches the example image: size(100,100, P3D); int concentration=300; background(0); noStroke(); spotLight(51, 102, 126, 50, 50, 400, 0, 0, -1, PI/16, concentration); translate(80, 50, 0); sphere(30); Regards, Patrick.

I have adapted this example to make a row of vertical sliders, but keep activating them all at once (undesirable!) How to adapt the code at the example above to prevent both bars being activated? Typo in TExtMode () refernce num_1273764002.html Processing Discourse/Website, Documentation, Book Bugs num_1273764002.html Thu, 13 May 2010 08:20:02 +0000 here : <a href="file:///Applications/Processing.app/Contents/Resources/Java/reference/textMode_.html" target="_blank">file:///Applications/Processing.app/Contents/Resources/Java/reference/textMode_.html</a> Only is repeated twice , is this a typo The SHAPE mode draws text using the the glyph outlines of individual characters rather than as textures. This mode is only only supported with the PDF and OPENGL renderer settings. With the PDF renderer, you must call textMode(SHAPE) before any other drawing occurs. If the outlines are not available, then textMode(SHAPE) will be ignored and textMode(MODEL) will be used instead. <img src="yabbfiles/Templates/Forum/processing_one/wink.gif" border="0" alt="Wink" title="Wink" /> Spam :( num_1265624003.html Processing Discourse/Website, Documentation, Book Bugs num_1265624003.html Tue, 11 May 2010 02:41:58 +0000 Removed (it was user 'sudy').

I usually don't make a fuzz about these glitches as it might be a maintenance phase, some hip-cup from the host or something. Seems back to normal now.

The images must be in the sketch's "data" directory to load correctly. Select "Add file..." from the "Sketch" menu to add the image. Processing currently works with GIF, JPEG, and Targa images. The color of an image may be modified with the tint() function and if a GIF has transparency, it will maintain its transparency. </div> I think the blue part belongs more to loadImage() page. The image formats sentence too, but I wanted to point out that it misses PNG format... And the "if a GIF has transparency" part too. Well, it should be "if image has transparency", since the image can be created from scratch. createGraphics ref is inaccurate num_1271238026.html Processing Discourse/Website, Documentation, Book Bugs num_1271238026.html Fri, 16 Apr 2010 14:32:17 +0000 Thanks.

There is a 32-bit version of the JVM on Snow Leopard, use that. The simple explanation is that you add -d32 on the command line, but if you're going outside the Processing environment, you need to read up on that yourself. If you're going to develop Java code, you need to research how to be a Java developer.
