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.

static void vtkOpenGLGL2PSHelper::SetLineWidth

(

float

lineWidth

)

[inline, static]

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

Definition at line 44 of file vtkOpenGLGL2PSHelper.h.

static void vtkOpenGLGL2PSHelper::SetPointSize

(

float

pointSize

)

[inline, static]

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

Definition at line 56 of file vtkOpenGLGL2PSHelper.h.

static void vtkOpenGLGL2PSHelper::EnableStipple

(

)

[inline, static]

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

(

)

[inline, static]

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