Different Acceleration Techniques

Reference Dataset
Mixed transfer function with lot of transparency which tends to slow rendering without empty space skipping
Image Size: 512×512 631 Slices
Render Resolution: 512×512 Pixel 512 Raysamples
MacBook Pro NVIDIA GeForce GT 750M 2048 MB


Simple 9
+Empty Fragment Skipping (Air) 9
+Empty Space Skipping (Function Alpha) 19
+Gradient Map 30
+Interleaced Rendering >60

Using different acceleration techniques it is possible to render high quality images in realtime even on low end GPU’s
