[osg-users] Swapping out geometry in the cull visitor for just the shadow camera?

Hey all, I have a shadowed scene that hosts a detailed city model and some 15000 objects using instanced geometry that also casts shadows. The instance positions are provided through a 2D float texture (128x128) to the vertex shader. To reduce the render times I was thinking that I should maybe

Re: [osg-users] model rendering glitch on osg versions 3.0.1

Hi Grey, I have just tested the OSG-3.2 branch and OSG svn/trunk and both load the two .stl ( CoffeeSpoonHolder.stl and CoffeeSpoonHolder2.stl) perfectly, with no odd lighting affects. From the svn log for stl plugin there was a patch applied a couple months after the OSG-3.2.0 release: $ svn

Re: [osg-users] model rendering glitch on osg versions 3.0.1

Thank you so much! Now it makes perfect sense why the behavior I was seeing didn't match the code; I didn't realize that the version on the repo wasn't released yet. I guess I'll see about putting 3.2.1 on all my computers. Thanks again! --Grey -- Read this topic online here:

Re: [osg-users] [osgPlugins] bug stl pugin?

Just to follow up on this, I've confirmed that the behavior we're each seeing is caused by the same bug. The STL plugin for 3.2.0 does not initialize its normal vector array correctly (it reserves all the memory it needs, but only fills in 1/3 of it), which results in undefined behavior. For

[osg-users] Slaves, RTT, and HUD

Hello, I'm looking to get the following scenario working: A scene with a HUD rendering on a distortion mesh using slave cameras. What I've tried so far is... 1. A normal Viewer class with two Cameras in the scene graph, one on a pre-render pass that renders the main

Hi Ben, Have a look at the osgdistortion example as it does exactly what you describe you want to do. Robert. On 4 November 2014 19:53, Ben Strukus ben.stru...@flyte.com wrote: Hello, I'm looking to get the following scenario working: A scene with a HUD rendering on a

Re: [osg-users] Slaves, RTT, and HUD

Hi Robert, The osgdistortion example is a great resource and I've used it quite a bit to set up the RTT and the distortion mesh, however when it comes to rendering a HUD (text, in my case) to that texture using slaves, I'm not seeing that being done in the example. Here's what I have: -

Hi Christion, you could use a switch above the 2 geometries or different cullmasks for the geodes and control it via the cameras cullmask/setting the switch before culling Hey all, I have a shadowed scene that hosts a detailed city model and some 15000 objects using instanced geometry that
