• Added functionality required for WineD3D's DirectX wrapper
• Introduced SGL_WINED3D_DONT_VFLIP for Windows, which ensures that DirectX applications running via WineD3D will have their framebuffers properly oriented.
  • By default, this is set to false. Set to true to enable.
• Added support for window resizing
• Renderer/vendor strings now pass through the hosts strings
  • GL_RENDERER = SharedGL using HOST
  • GL_VENDOR = SharedGL and HOST
• Improvements to texture upload functionality

SharedGL v0.6.0

Change log:

• Implementation

• Server:
  • Added support for using network protocol instead of shared memory
    • Added command line arguments:
      • -n: enables networking
      • -p [PORT]: override default port of 3000
    • Server will output the IP and port for LAN usage
• Client:
  • Added environment variable for communication across a network
    • SGL_NET_OVER_SHARED=address:port
  • Fixed crashes from glBufferData
  • Added framebuffer configs to GLX backend

SharedGL v0.4.1

Patches:

• Fixed spinlock on Windows; frame glitches remain, however command garbling should no longer occur.

Refer to release v0.4.0 for full changelog.

SharedGL v0.4.0

Change log:

• Server:
  • Added multi client support
    • Linux: Works
    • Windows: Works with modified virtio driver, located in ../sharedgl/kernel/windows/
      • Clients are still compatible with VirtIO's IVSHMEM driver, but will lack multiclient functionality
  • Added colored output to the terminal
  • Notify user whenever there isn't enough memory allocated
  • Made overlay transparent
  • Added memory usage to overlay
  • Seg faults now output the current command before exiting
• Client:
  • Fixed glGen... functions
  • Fixed gl...Pointer functions

Included in this release:

• sharedgl-v0.4.0-linux.zip: Contains server (sglrenderer) and OpenGL client for Linux (The kernel module required for Linux VMs is not included and must be compiled in the guest)
• sharedgl-v0.4.0-linux-optimized.zip: Contains the same as above but compiled with optimization (recommended)
• sharedgl-v0.4.0-windows.zip: Contains OpenGL installable client for Windows
• sharedgl-v0.4.0-windows-driver.zip: Contains a modified IVSHMEM driver for multiclient support on Windows (10, x64) (not required)
  • If you use this custom driver, VirtIO's IVSHMEM must be uninstalled and test signing must be enabled

SharedGL v0.3.1

• Changes to linux:

  • Server renamed to sglrenderer to avoid confusion

• Changes to windows client:

  • Removed WGL overrides
  • Removed GDI hooks
  • Reduced binary size
  • Client renamed to sharedglXX.dll
    • 32-bit and 64-bit is now supported
  • Client is now an ICD, must be installed rather than dropped in as a replacement for opengl32.dll
    • Install library by running wininstall.bat
    • Uninstall library by running winuninstall.bat

SharedGL v0.3.0

• Most/all functions up to OpenGL 2.1 have been implemented
  • By default, SharedGL will now report 2.1
  • Draw functionality is still a bit buggy, prone to crashing
• Fixed GL_RGB8 with textures
• Added GL_LUMINANCE_ALPHA support for textures
• Fixed glGenVertexArrays where parameter GLsizei n now gets handled by the client instead of being passthroughed
• Added glBindFragDataLocation
• Added additional GLX functions/functionality for comptability
• Added client-side environment variables
  • Users may now specify GLX_VERSION_OVERRIDE=X.X, GL_VERSION_OVERRIDE=X.X, and GLSL_VERSION_OVERRIDE=X.X for version control on the client side (otherwise, use whatever the server reports, which can also be changed with -g X.X)
  • Overriding the GLSL version can only be done on the client side
• Added support for 1D and 3D textures
• Added glGetBooleanv and glGetDoublev
