Hi Robert,
I understand the multitexturecontrol example, I modified it and slenderized it,
so that I simply can shift the textureWeight between my two examples.
But the output is not correct. I suppost my model is not correct textured.
therefore I need to know what a) the right structure is or b) what the reight
procedure is to generate the right structur.
Unfortunately the is no doc so I failed to learn it myself.
My startingpoint:
I have a model, which has a texture. Aditionally I have a not used 2nd
texturefile, which I'd like to ambed as second user, so I can switch between
texture1 und texture 1 ( day texture and night texture).
I load my model, and put it after an osgFX::MultiTextureControl node.
if i switch textureweight, it changes the look, the background behind the
texture changes, and if I focus totaly to the second texture, no texture is
visible.
what wiiould be the correct way to texturize my model.
Because one texturunit is in use, I suppose the textureVertices shouldn't be
any problem, because they exist already.
I simply want to change change the texture.
This was my code to add the 2nd texture:
Code:
bool airportCreator::addTexture( osg::Node* node_, std::string textureFile_,
int textureUnit_)
{
// check to see if we have a valid (non-NULL) node.
// if we do have a null node, return NULL.
if ( !node_)
{
return false;
}
osg::Geode* geode = getFirstGeode( node_ );
if (!geode)
return false;
osg::Texture2D* texNode = new osg::Texture2D;
// protect from being optimized away as static state:
texNode->setDataVariance(osg::Object::DYNAMIC);
// load an image by reading a file:
osg::Image* texImage = osgDB::readImageFile(textureFile_);
if (!texImage)
{
qDebug() << "Error couldn't find texture '" << textureFile_.c_str()
<< "', quiting.";
return false;
}
// Assign the image we read from file to the texture:
texNode->setImage(texImage);
// Assign texture Node to node.
//node_->getOrCreateStateSet()->setTextureAttributeAndModes( textureUnit_,
texNode, osg::StateAttribute::ON );
geode->getStateSet()->setTextureAttributeAndModes( textureUnit_, texNode,
osg::StateAttribute::ON );
return true;
}
Can you help me?
Thank you in advance,
Torben
