Model the GL VB after D3D11 one, where there are no data read backs, however this means
an extra memory copy of the buffer. 4th level uniform subdiv on Car, glGetBufferSubData
was taking 50% of CPU time before (actual subdiv 22%), now that is gone. Full CPU Draw
62ms -> 54ms, looks like most of overhead now is just waiting on GL queries).
- add #ifdefs to work around the different versions of glfw
- add cmake logic to parse other packages versions and set minimum requirements
- fix X11 dependencies for static builds of glfw
- general Find.cmake cleanup
fixes#101
In example code, GLUT has been replaced with GLFW so that glViewer/ptexViewer can run on OSX (10.7 or later).
OSX note: still have some problem with clang, may need to explicitly specify gcc on cmake cmdline
-DCMAKE_CXX_COMPILE=/usr/bin/g++
fixes#98
- remove the GL error check in cudaGLVertexBuffer :
* unrelated GL errors left on the stack were triggering erroneous
vertexBuffer allocation errors
* we should not be checking for GL errors here anyway (as most other
buffer allocations aren't checked either)
- add some pointer checking in the GL / D3D drawContexts in case the
vertexBuffer pointers passed are NULL
- add some additional typedefs in OsdError to report some of the new
CUDA / GL related errors
- consolidate cmake compile flags
- turn on -Wall
- suppress hidden overloaded function warning when using Clang
(part of it is bug, part of it will require code refactoring
on our end)
- add support for Maya 2013.5 for windows in cmake module
- clean up some glew includes which break builds with MSVC Express
& Windows SDK
- move the bitmap for font_image into a compiled object
- remove some unused variables and other minor warnings
Note : this is a checkpoint, there are still a few more warnings to clean up...
fixes#96
- cmake should now be better at finding Maya installations on OSX automatically
- various dependency fixes for Maya plugins
- first pass at some code fixes to build Maya plugins on OSX
this not the final word on this : just like glutViewer, we will need a "_compat" version of these plugins
fixes#95
