I am looking for some rendered images, videos that were created in the last 1 year using VTK that show photoreal renders with features such as HDRI, image based lighting, ambient occlusion, ray tracing, global illumination, diffusion of light, physically accurate materials.
What am I trying to do?
I am trying to assess the work involved for creating a VTK based alternative to game engine architectural visualization solutions such as Unreal engine-Twinmotion, Unity, and film VFX render solutions such as Blender, Arnold, Renderman. I know VTK will handle very large mesh data and I can add more nodes if I run into large datasets. That level of parallelism is not available in commercial game engines or other CPU based renderers. What I am not sure about is the render quality I can get out of VTK, specially considering some of the algorithms for photorealism tend to involve a gather step that needs to see all the mesh data at the same time.
What are the recent developments that I know?
I see mention of openUSD (which is being adopted by the film, VFX and gaming community) in Khronos Group’s announcement on ANARAI 1.0.
More questions…
- Can I expect the future integration of USD with VTK to happen through ANARI?
- Should I see improvement of render quality in VTK since ANARI will connect VTK with Intel, AMD, Nvidia rendering engines?
- Will these improvements come at the cost of reduced parallelism?
- How far are we from importing a USD scene into Paraview?
