hi everyone !!. i have a problem with return viewer in a fuction, and to add
the viewer of the fuction in de main.
#include "ventana.h"
osg::Camera* ventana::createCamera(int x, int y, int w, int h)
{
osg::ref_ptr<osg::GraphicsContext::Traits> traits = new osg::GraphicsContext::Traits;
traits->x = x;
traits->y = y;
traits->width = w;
traits->height = h;
traits->doubleBuffer = true;
traits->windowName = "Funcion de Ventana";
traits->windowDecoration = true;
osg::ref_ptr<osg::GraphicsContext> gc = osg::GraphicsContext::createGraphicsContext(traits.get());
osg::ref_ptr<osg::Camera> camera = new osg::Camera;
camera->setGraphicsContext(gc.get());
camera->setViewport(new osg::Viewport(0, 0, traits->width, traits->height));
return camera.release();
}
osgViewer::Viewer* ventana::crearMultipleVentana(int numeroColumnas, int numeroFilas)
{
int totalWidth = 1024, totalHeight = 768;
osgViewer::Viewer viewer;
int tileWidth = totalWidth / numeroColumnas;
int tileHeight = totalHeight / numeroFilas;
//Cremos una instancia de la nueva clase para llamar a la funcion para crear la ventana
ventana* myVentana = new ventana();
for (int i = 0; i<numeroFilas; ++i)
{
for (int j = 0; j<numeroColumnas; ++j)
{
osg::Camera* camera = myVentana->createCamera(tileWidth*j, totalHeight - tileHeight*(i + 1), tileWidth - 1, tileHeight - 1);
osg::Matrix projOffset = osg::Matrix::scale(numeroColumnas, numeroFilas, 1.0) * osg::Matrix::translate(numeroColumnas - 1 - 2 * j, numeroFilas - 1 - 2 * i, 0.0);
viewer.addSlave(camera, projOffset, osg::Matrix(), true);
}
}
return &viewer;
