Re: [osg-users] array of floats to a shader?

PM To: 'OpenSceneGraph Users' Subject: Re: [osg-users] array of floats to a shader? I haven't used an array Uniform before either. In the past I've used a 1D float texture. If you get this to work, let us know how it goes. Paul Martz Skew Matrix Software LLC http://www.skew-matrix.com +1 303 859

Re: [osg-users] array of floats to a shader?

Hi Shayne, I was successful in getting a floating point array uniform going for my shader. At Paul's request, here's what I did... In the shader setup code: [...] In the update callback: And what about the shader itself? How do you access it from there? Is it as simple as float

[osg-users] array of floats to a shader?

All, I have a simple question that perhaps someone can answer. I need to send an array of floats to my vertex shader. My question is, is there any support in OSG to do this? Looking at the osg::Uniform class, I don't see any direct support for doing this. Is there anything in OSG that
