Hello guys,
I'm trying to write and then read back float data from an image but for some
reason only the last written data seems correct
code:
dirImage->allocateImage((int) vertices.size(), (int)vertices.size(),
(int)vertices.size(), GL_RGB, GL_FLOAT);
for ( unsigned int i = 0; i < vertices.size(); i++)
{
osg::Vec3 pos = vertices[i];
(float &)dirImage->data(i)[0] = pos.x();
(float &)dirImage->data(i)[1] = pos.y();
(float &)dirImage->data(i)[2] = pos.z();
std::cout<<"actual.x is"<<pos.x()<<std::endl;
std::cout<<"actual.y is"<<pos.y()<<std::endl;
std::cout<<"actual.z is"<<pos.z()<<std::endl;
std::cout<<"pos.x is"<<(float &)dirImage->data(i)[0]<<std::endl;
std::cout<<"pos.y is"<<(float &)dirImage->data(i)[1]<<std::endl;
std::cout<<"pos.z is"<<(float &)dirImage->data(i)[2]<<std::endl;
}
can anybody point out the mistake, sorry if its too silly.
