* TGLFormat, TGLWidget
  Add handling of multi-sampling formats for GLX.
  WGL implementation is still missing.
  The value is taken from TEnv "OpenGL.Framebuffer.Multisample".

* TGLViewerBase
  Use TGLCapabilityEnabler for switching on bleniding.

* TGLViewer
  Remove flas fInitGL and associated functions.
  Set sane GL state on every Draw().
  Consolidate image extraction from frame-buffers.

* TGLEmbeddedViewer, TGLSAViewer
  Remove calls to ResetInitGL().

* TGLRnrCtx
  Remove fGrabBuffer and fGrabbedImage members, only keep fGrabImage flag.
  All the rest is handled internally in TGLViewer now.

* TGLFBO
  Add support for multi-sampling FBOs.

Revision 29724 - (view) (download) (as text) (annotate) - [select for diffs]
Added Fri Aug 7 16:10:57 2009 UTC (5 years, 5 months ago) by matevz
File length: 1244 byte(s)

Add support for frame-buffer objects (FBO).
This allows for offscreen rendering into separately instantiaded
frame-buffer. Useful for saving of images whan the GL window is now
visible or for rendering into textures.

Requires OpenGL-1.5 (detected at run-time with GLEW).

In TGLViewer add new function
   Bool_t SavePictureUsingFBO(const TString &fileName, Int_t w, Int_t h);
that allows saving of an image with any resolution supported by the
local GL implementation (8192 pixels on my desktop).
