Jiayi has been building upon Gaspard’s and Timothee’s ideas and code. She is investigating other “scattering” methods. They will be less photorealistic than those rendering from Siemens, et al., but her methods target near-real-time rendering on common hardware. She is currently porting them to vtk.js. Thanks for the links to the data, we’ll include them in the demos.
As Timothee stated, a big challenge is the transfer functions…and that isn’t solved by her methods either…
