Re: [osg-users] osgEarth fading effect?

Robert, I set our terrain as input (output.ive) to the same osgmultitexturecontrol example. It is returning false from the function where node to the type of multitexturecontrol is searched from our terrain i.e.,dynamic_cast to multitexturecontrol is failing. Expected elevation

Re: [osg-users] osgEarth fading effect?

Hi akilan, May we have got our wires crossed. You can create osgTerrain with more than one texturelayer. As default layer 0 is shown. You can blend to an of the other texture layers with the multi texture control. If I read your problem, I wonder If you are talking about fading to differenz

Re: [osg-users] osgEarth fading effect?

Hi zonk, To say straghtly, same region has been constituted by multi resolution tiles. The transition from coarser to better resolution tile will take place based on the height we are. As u said, exactly I like to know about the LOD popping by fadding only. Akilan. A --

Re: [osg-users] osgEarth fading effect?

Hi Akilan, thank you, than your question is my question too :) My thoughts: I don't know if osg already provides a fading node to fade in/out the subsequent scenegraph. If not, maybe you should develop one. This node could be used in your osgTerrain to introduce fading in the LOD mechanism.

Re: [osg-users] osgEarth fading effect?

HI Akilan, Have a look at the osgmultitexturecontrol example as it does exactly what you are looking for. Robert. On Fri, Apr 16, 2010 at 6:12 AM, Akilan Thangamani akilan.thangam...@gmail.com wrote: Hi robert true. My imagery tiles have been constructed as layers such a way coarser

[osg-users] osgEarth fading effect?

Hi, Similar to osgEarth which provides to set fading effect to the terrain tiles, could it be is possible to get the same effect directly from osg alone and how? Bcoz, to exploit that feature from osgEarth, it puts some constraints like the terrainDB should be generated with --terrain

Re: [osg-users] osgEarth fading effect?

Hi Akilan, When you say fading effect do you simply mean that you want to change the alpha value of the terrain so that it becomes transparent? Robert. On Wed, Apr 14, 2010 at 8:12 AM, Akilan Thangamani akilan.thangam...@gmail.com wrote: Hi,      Similar to osgEarth which provides to set

Re: [osg-users] osgEarth fading effect?

Hi, I think he intends fading out tiles (via alpha) which are replaced by tiles with higher or lower LOD. Is there any predefined method? Would be nice to test, especially regarding performance :) Cheers, Torben -- Read this topic online here:

Re: [osg-users] osgEarth fading effect?

Hi Akilan, If you're talking about the FadeLayerNode in osgEarth it's basically just doing a shader that blends multiple texture units together. The osgFX::MultiTextureControl does something similar without using shaders is so that we could support fading along with imagery that contains an
