      Remove ES2 support for VTK 8.0 · 0f750114
      Ken Martin authored
      ES2 is causing headaches and code mess and is
      getting old. Remove for 8.0 so we can focus on
      more modern APIs. Most Apple and Adroid devices
      from the past 4 years support ES3.

      This commit reindents the code with the following utility:
      This utility changes the positions of the braces so that they are no

      Add Depth stage to polydata fragment shaders. · 101f9eeb
      David C. Lonie authored
      The depth peelers currently assume gl_FragCoord.z is always the depth,
      but the imposter shaders in Domains/Chemistry modify the depth.
      This patch adds a //VTK::Depth::Impl hook into the fragment shader
      template, before any depth peeling processing is applied. The depth
      is stored into gl_FragDepth, and all depth processing now uses this
      variable instead of gl_FragCoord.z.

      Add depth peeling benchmark. · 1b26ec3c
      David C. Lonie authored
      This 10M triangle scene stresses depth peeling implementations to see
      how well they perform.
      Results (nVidia Quadro 2000M, Release build):
      vtkDepthPeelingPass: 1.2 FPS (0.77s first frame, 0.83s subsequent)
      vtkDualDepthPeelingPass: 2.5 FPS (0.56s first frame, 0.40s subsequent)
      We see a roughly 50% improvement with the new dual algorithm, since
      the dual algorithm peels 2 layers per geometry pass.
      For reference, simple alpha blending results in 49 FPS, 0.18s first frame,
      0.020s subsequent.

      Add vtkDualDepthPeelingPass. · 19d945f7
      David C. Lonie authored
      This implements a new depth peeling algorithm that peels layers of
      fragments from both the front and back of the translucent geometry at
      This also introduces vtkOpenGLRenderPass, which provides a virtual API
      that allows custom shader code replacements without the need to edit
      all mappers.
      The older vtkDepthPeelingPass has been updated to use the new
      vtkOpenGLRenderPass API, and is left in VTK as a fallback for drivers
      that lack support for the dual peeling features (floating point textures
      in particular).

      A fix for picking combined with depth peeling · 8af6e111
      Ken Martin authored
      A fix for picking combined with depth peeling and some cleanup.
      Picking (not using a hardware picker) was not clearing the
      LastRenderingUsedDepth peelign flag and that was causing issues.
      Switched to that that flag is not sued but instead the information
      objects are used.
      (cherry picked from commit 7e23fd65)

      A depth peeling fix when compositing · 033623d4
      Xabi authored
      When compositing we need the alpha to be correct when it
      comes out of depth peeling. Previously it was being set
      to 1.0.

      Make VTK work with OpenGL 3.2 Core · b8a4007f
      Ken Martin authored
      Lots of changes to make VTK work with both 2.1 and 3.2 versions
      of OpenGL. The main differences in OpenGL 3.2 are that the
      following features no longer are supported
      intensity textures - recoded to use red
      luminanace textures - recoded to use red
      line stipple - vtk error macro
      querying extensions in one string - replaced with multiple calls
      pixel transfer bias and scale - recoded to be done in the shader
      glPush and PopAttrib - recoded to get and set instead
      texelFetchBuffer - defined to texelFetch
      txture1D - defined to texture
      texture3D - defined to texture

      A few dashboard fixes as described below · 59b539a0
      Ken Martin authored
      GPUVolume rendering was activating texture units and never
      deactivating them.  The TextureUnitManager was allowing this
      when it should not have been.
      GenericCompoistePolyDataMapper was not releasing graphics
      resources on its helper.
      Added in some opengl error reporting logic that someone had added
      to only the old backend.
      DepthPeeling was not releasing all of its graphics resources.
      Removed a couple extra includes.
      Added a MakeCurrent in TextureObject when it releases its
      graphics resources. Sometimes this happens when another window
      is current as a side effect.

      A number of transparency related issues fixed · 944ee020
      Ken Martin authored
      A few good fixes in here that are all related. The biggest is a
      fix to OpenGLActor to use the more comprehensive GetIsOpaque
      method in determining if an actor is opaque. The old code only
      looked at the property's opacity. This is why you would see folks
      setting somethings opacity to 0.99 to get it treated as translucent
      because the actor code wasn't handling it correctly. This change
      resulted in 3 new valid images for tests that were rendering
      translucent items as if they were opaque. I removed these tests
      from the old backend as I did not want to change the behavior
      for that backend.
      Next up is depth peeling. OpenGL2 depth peeling would render
      a number of peels up to the limit and then just stop. Any geometry
      left between the opaque layer and the last translucent layer was
      just thrown out.  This created very noticable artifacts and was bad.
      This change makes it so that when it gets to the last pass, it will
      render all remaining geometry using alpha blending....

      Add in depth peeling pass and a couple other passes · 925f5066
      Ken Martin authored
      Convert depth peeling render pass to the OpenGL2 backend.
      Also add a new class that encapsulates the basic rendering
      steps that VTK uses.
      Modify the renderer to use the depth peeling pass instead of
      having two copies of the code lying around. Removed the depth
      peeling code from Mapper2D as it is no longer needed now that we
      have CopyToFrameBuffer working. That is a lighter weight way to
      get a quad up on the screen. Plus that keeps the depth peeling
      code more localized as it should be. Clean up a lot of depth
      peeling code that was in the renderer and now there are cleaner
      ways of doing it (passing information keys).
