Re: [osg-users] I want to know the time of rendering.

Hi Jerome, When you say you want to know the time of rendering, do you mean the time in seconds since the start of the viewers frame loop? Time of day? Also how do you want to use the time? This is important to know as depending upon what task you have there are different ways to get the time

Re: [osg-users] [3rdparty] ShadowedScene doesn't display HUD Camera

Hi Alex, There isn't any away that a 3rd party will be able to guess your mistake given the scant details provided. The idea of mixing shadows and HUD is rather odd, one wouldn't normally do this, rather one would have a 3D scene graph with shadows representing your world and if one needs a HUD

Hey again. As I posted before I managed to render to texture a scene and projected it onto a Geometry. But it is just an image of a scene and the RTT camera can't move around my object (cessna.osg). Is there a way to move the camera freely around like you would do with viewer's camera? lg

Thanks, Robert. I attached two screen shots. I found that aliasing would only appears on the side of the cube that has not been filled. For example, the cube size is 100 x 100 x 20. If the cube is fully filled colour on all voxels, there is no aliasing on each surface. Once there is a

Hi Clement, The datasets you are working of will always challenge a ray traced sampler as there is sudden cutoff to a flat face so that any small change in adjacent pixels can result in a enough of different sampling as to result in a visible step. Increasing sample density will usually reduce
