I had a look on osgAnimation and osgCharacter and it seems like skeletal
animation is something similar to what I like to do.
Now I'm trying to send uniform arrays to the shader. In the end I like to send
the transform matrices to the shader, but even with uniform float array it
doesnt seem to work. I've tried to use setElement() and setArray() but nothing
work.
This is my setElement() code, trying to change the color of the object.
Code:
osg::Uniform* rgbUniform = new
osg::Uniform(osg::Uniform::FLOAT,"rgb",3);
float r = 0.5; float g = 0.7; float b = 0.8;
rgbUniform->setElement(0,r);
rgbUniform->setElement(1,g);
rgbUniform->setElement(2,b);
stateset->addUniform(rgbUniform);
The fragment shader
Code:
uniform float rgb[3];
void main( void )
{
gl_FragColor = vec4(rgb[0],rgb[1],rgb[2],1.0);
}
