Re: [osg-users] Shadows in OSG

I suggest looking at StandardShadowMap, MinimalShadowMap and the various LiSPSM variations; based on my experience with osg 2.8.3 they offer the most robust implementation of shadows. There is also a debugging mode that you can enable that renders the depth map which is extremely useful. As

Hi, How about learning the way OSG structures the shadow code. I found it difficult understanding how OSG manage shadow. Could anyone briefly explain the shadow codes in OSG or is there any way I could learn more on them? Thank you! Cheers, Linda -- Read this topic online

[osg-users] Shadows in OSG

Hi everyone, I am trying to learn to the detail implementation of shadowing in OSG and maybe to develop my own shadow technique. Could anyone give some advices on where I should get started or if there is any online resources that I could start learning with? Thank you! Cheers, Linda

[osg-users] Shadows and osg::Fog?

Hi, I'm wondering if anyone tried the combination of SoftShadowMap shadows and osg::Fog. With 2.2.0 and svn I've tried to use it with SoftShadowMap but that's not working. I suspect that it's not working because of the shader that's being used, but that's just a guess. ShadowTexture and

Re: [osg-users] Shadows and osg::Fog?

Aha, I guessed that, thanks for the confirmation. So you say that fog should be part of the shadow shader, and not a separate, extra one. I did not do that much with shaders yet, except for using the osg-included ones. I cannot have a hierarchy of nodes with shaders, I guess? If I cannot have

Re: [osg-users] Shadows and osg::Fog?

Hi, Composing shaders is next to impossible in a general pupose way, each GLSL Program needs to know all the shaders that contribute to it and have a main shader that glues them all together. Ok, I understand, this would be tricky indeed. And again hard-coded in some (other) way ;-) I am
