Main topic: Keyframe animation
- See this discussion and this question
- Discussed keyframe animation approaches and progress
- Use of dummy master node in Sequence to control interpolation / timestep
- Keyframe is the actual, non interpolated data
- Pre-calculating interpolated data vs interpolate at creation of animation
- Data / memory usage is relevant here
- Repeating sub-sequences? (ex. model rocking)
- Role of Sequences / Sequence Browser / Dependency minimization
- We want to avoid hard dependencies on new interpolation nodes / methods
- Node Sequencer is part of Sequences
- Interpolation is the role of the Browser?
- How does the screen capture module play into this?
- Key frame editing!
- Edit camera paths / focus using new markups - oriented b-spline
- Transforms and transfer functions already have editors
- Reconciling requested FPS with data sources
- Invented term virtual node (data generated at runtime)
- Moving sequences into the core due to the increasing usage (as remote module to start)
Volume rendering: Thoughts
- Discussion of Drishti Software
- Rendering improvements in VTK: physics based rendering
Large Volume Support: Pending issues
- Need more support than just visualization
- Approach should address segmentation and other interactions
- Better management of OpenGL/GPU errors and info
- Texture memory management
- Figuring out how much GPU memory is available is hard
- Would be a super useful tool in VTK
- level of detail in hierarchical volumes
- mipmapping for volume rendering??
