Hi Émeric, Thanks for your information. I am thinking whether it is easy way to show the volume image on web page. I also found some examples using texture2d to form volume rendering. I may try this option. Thanks.

This is something WebGL 2.0 is supposed to solve. In the meantime, there seems to be a trick involving GLSL [2] but I didn't look deep into the code/solution. BTW, how did you use WebGL with OSG? I know of OSG.JS [3], a JavaScript reimplementation of OSG API aiming to develop WebGL applications, but that's a totally different project.
