Algorithm for "neon glow" graphics programming -

-

i searching article or tutorial explains how 1 can draw primitive shapes (mainly simple lines) (neon) glow effect on them in graphical output of computer program. not want sophisticated stuff example in modern first pirson shooters or alike. more in search simple solution, lines in picture: http://tjl.co/blog/wp-content/uploads/2009/05/neonstripes.jpg -- of course drawn computer program in case.

the whole thing should run on modern smart phone, hardware bit limited.

i know bit opengl, not much, unfortunately bit lost here. did research on google ("glow effect algoritm" , similar), found either highly complex stuff 3d games, or tutorials photoshop & co.

so need in-depth article on subject, not on advanced level. hope thats possible... have started opengl, did minor graphics programming in past, long-year programmer now, understand technical papers in general.

does of know of such article/paper/tutorial/anything?

thanks in advance advices! cheers!

its jus bunch of lines different brightness/transperency. basically, if want glow effect 1px line, in size of 20 pixels, draw 41 lines width of 1 px. middle line base colour, other lines colours gradiently go base color 100% transperency (like in example) or darkest colour variant (if have black background, no transparency). it. :)

c# - How to set Z index when using WPF DrawingContext? -

how set z-index drawing object when using drawingcontext.drawxxx() methods? the object drawn last have higher z index. can't change index of drawn objects. way draw in order. if using wpf (as placed tag), can use, example, canvas control. create shapes need like polyline obj = new polyline(); //... // ... set properties of obj and add them canvas uielementcollection: yourcanvasname.children.add(obj); //or yourcanvasname.children.insert(i, obj); first items of collection have higher z index. advantages in way: no need redraw on window changes, can anytime move objects , change order.

razor - Is this a bug in WebMatrix PageData? -

i think may have found bug in webmatrix's pagedata, not sure. concerns how pass data partial page calling page. in webmatrix documentation (tutorials, e.g. " 3 - creating consistent look ", , example code), pagedata recommended mechanism pass data between pages (e.g. content page layout page, or partial page). however have found not work other way, pass data partial page calling page. modifying or adding entries in pagedata in partial page, not seem calling page. cutting right down simplest possible example, in test page may have this: @{ pagedata["test"] = "initial entry"; } <p>before calling partial page, test value @pagedata["test"]</p> @renderpage("_testpartial.cshtml") <p>after returning calling page, test value @pagedata["test"]</p> and in _testpartial.cshtml page might have this: @{ pagedata["test"] = "modified entry"; } <p>in partial page...

visual c++ - Using relative values in array sorting ( asm ) -

i need sort through array , sort each individual row in array in ascending order. doesn't seem going (surprise!) keep getting hit 2 errors: a2101: cannot add 2 relocatable labels , a2026: constant expected here's sort, makes sense me, think i'm still trying implement high-lvl language techniqes assembly. there way around not being able use relative values? (the array 7 rows 9 columns, btw). mov cx, 7; cx = number of rows outer: ; outer loop walk through rows push cx mov cx, 9 mov row, cx ;rows middle: ; middle-loop walk through columns push cx sub cx, 1 ;cx = cx-1 mov column, cx ;columns inner: ;inner loop - compare , exchange column values cmp marray[row*9 + column], marray[row*9 + column+1] xchg marray[row*9 + column+1], marray[row*9 + column] ; compare , exchange values marray table inc column loop inner pop cx loop mid...
