Hi @sankhesh,
They were running on newest Chrome(113+) on Windows 10, graphic cards are GTX1650 and RTX3060, driver version is 31.0.15.1702, date 8/7/2022, both setup have the same issue, the older(GTX1650) behaves much obviously, the frame on RTX3060 will drop from 50 to about 25 with the newer vtk.js.
I’ve made another CPR demo running with native webgl api with a shader which had a uniform sampler3D that used a texStorage3D on both setup, the 2d texture texStorage should be supported.
I just have these 2 setups running, my macbook pro is too old that the graphic card can not work with volume rendering smoothly, other setups are not tried yet.
For the volume rendering issue I turned the AutoAdjustSampleDistances on mapper to false, the blur will not show, but the lines are still shown with aliasing, is there anyway to turn it off? This will not happen when there is just the polyData without the volume.
