      OpenGL error hunt -- dashboard cleanup · 6455c581
      Burlen Loring authored
      Use static version of vtkOpenGLCheckErrorMacro in helper class
      that's not a vtkObject in vtkPistonMapper. Don't check for OpenGL
      errors in vtkGL2PSExporter::Write it doesn't use OpenGL directly.
      Fix warning about narrowing cast. Use vtkOpenGLCheckErrorMacro
      before return in vtkOpenGLImageSliceMapper::TextureSizeOK.

      OpenGL error hunt · a6fa3e37
      Burlen Loring authored
      This patch implements OpenGL error checking in VTK.
      OpenGL's error handling implementation error is designed such
      that internal error flags remain set with the first error that
      occurred until they are explicitly checked. With this design
      it's important to check and clear the error flags regularly
      else they become unusable as code checking for errors ends
      up reporting earlier undetected unrelated errors.
      This patch takes the following approach:
      1) at public entry points into code that uses OpenGL clear the
      error flags without reporting errors. This guards against
      reportinig unrealted errors, such as those caused by code
      outside of VTK. See vtkOpenGLClearErrorMacro
      2) before returning from functions that made OpenGL calls check
      for and report OpenGL errors. This detects Open GL errors in the
      function/method where they occurred facilitating debugging and it
      clears error flags so that user code doesn't detect errors caused
      by VTK. See vtkOpenGLCheckErrorMacro
      This patch cleans up a number of bugs that were detected by
      the new error checking and reporting.
      This patch also contains improvements for OpenGL pixel buffers, a
      renderbuffer object, and fast paths through framebuffer objects,
      and texture objects, and fast path for setting uniform variables,
      all of which are needed in vtkSurfaceLICPainter and
      vtkLineIntegralConvolution2D GPGPU code.

      ENH: Add math function for nearest power of two. · 93f35796
      David Gobbi authored
      There are several places in VTK where the bounding power of two is
      computed.  It is safer to centralize the code.  Use an O(log(N))
      algorithm instead of the O(N) algorithm that was used before.

      Replace polygons with triangle strips in vtkImageSliceMapper. · 6f063d9b
      David Gobbi authored
      The 3D image mapper displays the image as a texture on a polygon.
      Rendering the polygon with GL_POLYGON is deprecated in OpenGL 3
      and seemed to cause rendering issues with some drivers.  Switch to
      GL_TRIANGLE_STRIP to see if it fixes these issues.

      Modularize VTK tree layout · cdd4d6fd
      VTK Developers authored and Brad King's avatar Brad King committed
      Move source files from their former monolithic VTK location to their new
      location in modular VTK without modification.  This preserves enough
      information for "git blame -M" and "git log --follow" to connect
      modularized VTK files to their original location and history.

      ENH: Add new image mappers to VTK. · 9ac8f746
      David Gobbi authored
      New class vtkImageSliceMapper will draw slices of a 3D image, while
      new class vtkImageResliceMapper will draw oblique reformatted slices.
      New class vtkImageSlice is the corresponding Prop3D for the mappers,
      and is a replacement for vtkImageActor, which is now a subclass of it.
      New class vtkImageProperty controls window/level, lookup table, etc.
