v34.0.0

34.0.0 (2025-06-13)

Bug Fixes

• Check if cached opacity texture is deleted (533797c)
• Fix typescript (4a51712)
• Fix update of color and opacity textures (111f193)
• imagereslicemapper: be less sensitive for "snapping" to nearest orthogonal axis (68acd11)
• renderwindowinteractor: observe KeyPress events on RW container instead of document (8cba154), closes #1856
• VolumeMapper: Use the right volume property for texture creation (5f29c73)

Code Refactoring

• move the updatedExtent API to properties (bf98788)
• Move VolumeMapper rendering properties in VolumeProperty (6bc4642)
• OpenGL/Texture: use named parameters (7fbbaa8)

Features

• Add multi property handling to the volume actor (22db7b4)
• Add multi-image support for components to ImageResliceMapper (b5707df)
• KeyboardCameraManipulator: Add typescript (678489c)
• Multi component using volumes (4c9103a)

BREAKING CHANGES

• OpenGL/Texture: the create* methods now use named parameters rather
  than positional parameters.
• the updatedExtent API has been moved from the mappers
  to the vtkImageProperty and vtkVolumeProperty interfaces. vtkImageMapper
  does not yet honor the updatedExtent API.
• renderwindowinteractor: This may break key press event current behavior.
  tabIndex=0 is now added on RW containers.
• getTransferFunctionHash becomes getTransferFunctionsHash
  It takes a list of functions as argument instead of a single function
  Also ImageResliceMapper doesn't wieght color using mix.
• the volume mapper fragment shader is very different.
  This can cause shader replacements to break.
  refactor: Use the right matrices in volume FS shader
• Move vtkVolumeMapper's properties related to rendering in vtkVolumeProperty.
  Add a clear error message for these widely used methods.
  This is part of the MultiVolumeMapper feature.
