osx - Does OS X Lion provide OpenCL image support for Radeon 5770? -

-

on os x snow leopard (10.6.8), opencl image support not available on mac pro radeon 5770 graphics card. indeed believed common amd/ati radeon cards under snow leopard , earlier. specifically:

  clgetdeviceinfo(cddevices[uideviceused], cl_device_image_support, sizeof(g_bimagesupport), &g_bimagesupport, null);

results in g_bimagesupport being false.

i want know if has final release 10.7 (lion) , radeon 5770 graphics card in mac pro, can check see if cl_device_image_support returns true hardware?

an easy test download apple sample code raytraced quarternion julia-set:

http://developer.apple.com/library/mac/#samplecode/opencl_raytraced_quaternion_julia-set_example/introduction/intro.html

and build , run it. output on system sadly:

connecting amd ati radeon hd 5770... qjulia requires images: images not supported on device.

hope hear works in lion ...

i'm running lion 10.7.1 radeon 5770 , given example works great (yay!), running around 150fps. so... yay!

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...
