Re: [osg-users] osg::Vec3Array as uniform to Shader

2018-03-03 Thread Rômulo Cerqueira 
Hi,

I found a way to solve this problem: converting the array to texture.

Follows an example:


Code:

osg::ref_ptr image = new osg::Image;
image->setImage(myVec3Array->size(), 1, 1, GL_RGBA8, GL_RGBA, GL_FLOAT, 
(unsigned char*) [0], osg::Image::NO_DELETE);

osg::ref_ptr texture = new osg::Texture2D;
texture->setImage(image);

...

ss->addUniform( new osg::Uniform("vertexMap", texture) );




... 

Thank you!

Cheers,
Rômulo[/code]
