Better accuracy with picking
This issue was created automatically from an original Mantis Issue. Further discussion may take place here.
- Open office.binary.vtk
- Extract subset [10, 10, 0, 19, 0, 19]
- Surface Vectors
- Stream Tracer --line source Now try picking the end points. They always end up slightly above or below the surface.
Possible solutions:
- Use g-buffer selection to locate the cell then intersect the cell with the eye-ray to locate the pick point.
- Use z-buffer picking to locate approximate location, then re-render with clip-planes really close to the picked location thus giving better z-buffer accuracy.
