So i tried this magical NV_vertex_buffer_unified_memory because i want my app to run 7.5x faster. All i can produce is hard crashes, though. So, i reduced it to the case of binding only the index-array via bindless-stuff and leave the vertex-da]]> Sun, 21 Mar 2010 08:36:10 CDT http://www.opengl.org/discussion_boards/ubbthreads.php?ubb=showflat&Number=274440#Post274440 Posted by somboon:
Whoa thank for you in depth reply,you are the most generous guy on this board ^_^ . My implement is still frame rate dependent too and it also got some performance hit by require RGBA16F to store velocity map in range -1,1 .

[quote=yakovm]The mesh is not closed.[/quote] If the mesh is not closed how do you even define 'inside' and 'outside'?

Re (1) You don't have to use the full area of the texture image. You can use just part of it, and then adjust your texture coordinates to extract just the part of the image that you used. On the other hand, if you stretch the image to fill the]]> Sat, 20 Mar 2010 00:38:05 CDT http://www.opengl.org/discussion_boards/ubbthreads.php?ubb=showflat&Number=274386#Post274386 Posted by Pierre:
My other 3d are draw, and they are at the same place. mesh.FloatArray.Length return the numbers of case in array. mesh.IndexArray.Length is the same thing. My array for i use int in indexarray. My news code is: But it's the same thing.

It looks like, there is a memory error in the tess.c redbook example on the www.opengl.org: [url=http://www.opengl.org/resources/code/samples/redbook/tess.c]http://www.opengl.org/resources/code/samples/redbook/tess.c[/url] vertex = (GLdoub]]> Fri, 19 Mar 2010 13:54:44 CDT http://www.opengl.org/discussion_boards/ubbthreads.php?ubb=showflat&Number=274362#Post274362 Posted by YarUnderoaker:
Strange, but I do not get any errors, although the objects draw by Begin/End. Okay I'll have to write shaders that would draw a scene :( PS: a result of CUDA kernel is integer texture to. But I render it with shader.
