Detailed Description

Helper functionality for GL2PS exporting.

vtkOpenGLGL2PSHelper provides a number of static variables and methods that are used during GL2PS exporting. The rational behind this class is that GL does not include all of the information that GL2PS needs into its feedback buffer, and in certain situations GL2PS function calls need to be made alongside their GL equivalents, notably glLineWidth and glPointSize.

The static variables in this class are set by vtkGL2PSUtilities at the beginning of a GL2PS export render. This class fakes GL2PS calls like gl2psLineWidth in order to keep GL2PS from being a module dependency for vtkRenderingOpenGL.

Member Function Documentation

static void vtkOpenGLGL2PSHelper::SetLineWidth ( float  lineWidth)
inlinestatic

Call alongside glLineWidth(lineWidth) to inform GL2PS of the change.

Definition at line 44 of file vtkOpenGLGL2PSHelper.h.

static void vtkOpenGLGL2PSHelper::SetPointSize ( float  pointSize)
inlinestatic

Call alongside glPointSize(pointSize) to inform GL2PS of the change.

Definition at line 56 of file vtkOpenGLGL2PSHelper.h.

static void vtkOpenGLGL2PSHelper::EnableStipple ( )
inlinestatic

Call alongside glEnable(GL_LINE_STIPPLE) to inform GL2PS of the change. This must be called after calling glLineStipple(factor, pattern).

Definition at line 70 of file vtkOpenGLGL2PSHelper.h.

static void vtkOpenGLGL2PSHelper::DisableStipple ( )
inlinestatic

Call alongside glDisable(GL_LINE_STIPPLE) to inform GL2PS of the change.
