directx - DirectXTk GeometricPrimitive texture coordinates -


i'm using geometricprimitive scene elements, it's draw() call uses tx coords of 0-1 no opportunity (i think) change it.

if change texcoords in directxtk code itself, can textures repeat using larger texture coordinates; though don't want dependent on hacking toolkit code.

so, since draw() provides lambda callback, i'm wondering if there's opportunity remedy updating texture coordinates.

i'm using basiceffect rendering, if helps.

they use vertexpositionnormaltexture publicly accessible. if somehow provides me way walk vertex buffer , update tx coords, work me. i'm wondering if can map() or somehow else access buffer, walk vertices, update tx coords, , hope best.

is best (only) approach or there better 1 geometricprimitive?

i wound writing own shader render primitives , added uv transform. allowed me pass in xmmatrixscaling(10,10,10) example scale coords , larger repeat.

html - Outlook 2010 Anchor (url/address/link) -

i'm trying link specific pdf page msoutlook'10 or msword'10, #page=... anchor particularly useful , works fine elsewhere. unfortunately when click [ctr-k] in outlook or winword, links re-formatted assuming unc path. pdf file located on shared drive. using "file:" prefix links open pdf in adobe reader (outside of browser), , "http:" open inside browser. issue seem need open in browser "file:" prefix in order anchor work. know anchors work inside browser. outlook uses windows/explorer default program (based on file extension) seems open in adobe reader neglecting anchor. is aware of solution, link specific page or bookmark of shared-pdf ms outlook and/or winword link? common references: mailermailer.com/...anchor-tags-html-emails campaignmonitor.com/...anchor-links-in-email-newsletters/ stackoverflow.com/...anchor-in-pdf-document

javascript - Why does running this loop 9 times take 100x longer than running it 8 times? -

consider code: test = function() { } t = new test(); (var = 0; < 8; i++) { result = t instanceof test; } if change number of iterations 8 9 , loop take 100 times longer complete in latest version of firefox (41.0.1). tested on 2 different pcs , magic limit 8. here jsperf test used: http://jsperf.com/instanceof-8-times-vs-9-times does have idea why might happen? seems specific instanceof . not happen if else object, example check property. note: filed bugzilla bug this. jan de mooij mozilla team has posted details in bugzilla thread . here's simplistic interpretation of highly technical answers: in i < 8 case, firefox smart enough hoist result = t instanceof test; statement out of loop (according tests, doesn't seem omit altogether). in i < 9 case, apparently doesn't optimization . why? reason not clear, related fact 9 iterations threshold above function considered "hot" enough run through jit compiler. i < 8 cas...
