Another thing

Alright, ...this may be nitpicking, but I just counted 13 seperate instances of the powerOfTwo() function defined in seperate files: anyone against me cleaning this up and consolidating it (it's already defined in GemPixObj.h)? ...also, after a cvs update, I just recompiled and only came up with 10 warnings! And nine of those are debug() messages ;-) ...looking good... jamie

um, Grey or Gray?

...guys, we should really decide on one way to spell this: it seems to be arbitrarily one way or the other through out the source! ...seeing as there don't seem to be any brits helping out with the development, I vote for "Gray" l8r, jamie

text on a spline... (and text3d feature requests)
by B. Bogart 06 Apr '04

Hello all, I'm about to start a project and wanted to ask on this list your ideas on how to approach it. I would like to get a dynamic string/symbol(with spaces) to be rendered with text3d as if it is following a spline. Where the baseline of each letter is a tangent to the spline curve. I'd like to be able to move the control points of this spline curve and change the text (including the number of letters) dynamically. My first thought is to build a pmpd chain that will act as the "spline" then use tLia objects to control the position and rotation of individual letters (as separate text3d objects) Some issues are how to make a pmpd chain more like a spline, I guess having no flextion in the links? Spacing the letters could also be a challange. Any other ideas of how to approach this? How intensive is the math for calculating the position of the letters based on some real spline-curve equation? Any examples how I may go about this method? Any opions would be welcomed. As for text3d in general It would be very very nice to be able to have support for: * Text boxes that wrap the contents, by character, or by word, or with "-". A special line-break character{,sequence} would be nice too. You just define the bounding box for the text in gem units (or rows+columns) and it goes from there. Basically giving text3d the ability to manage multiple lines of text. * Jusification within this box (left right centre flush) * text following a spline? ;) Thanks all! Ben

Re: mouse coords

Hmmm, this is inconsistant with other platforms, Can't you just subtract 20 to the pixel location before passing it? So the top of the titlebar would be -20, the top of the GL 0 and the bottom would actually be the height of the window (not the height + 20) If there is no title-bar then don't subtract... I think the coords should be consitant in the window across platforms, otherwise pointer-entry projects would not be cross-platform. 20-pixels offset can be quite an anoyance doing collition detection!
