Hi Nie,
I guess there are no texture coordinates on your model.
As i've written before, you can generate them if they are in object
space anyways.
If TexGen is not available on your platform, you can generate them in
the vertex shader on the fly
Cheers

Hello Robert
Sorry for bothering you again.
I have tried using texture2D to create the gradation color and succeeded in
geometry like some boxes. But I failed in apply texture to STL models.
I succeeded in this one.
Code:
osg::Image *pImage = osgDB::readImageFile("icondata.png");
osg::Texture2D* pTex = new osg::Texture2D();
pTex->setTextureSize(400, 400);
pTex->setImage(pImage);
pTex->setFilter( pTex->MIN_FILTER,pTex->LINEAR);
pTex->setFilter( pTex->MAG_FILTER,pTex->LINEAR);
osg::Geode* geode = new osg::Geode();
osg::ShapeDrawable* drawable = new osg::ShapeDrawable(new
osg::Box(osg::Vec3(1,1,1), 200));
geode->addDrawable(drawable);
geode->getOrCreateStateSet()->setTextureAttributeAndModes(0, pTex);
_root->addChild(geode);
I tried to apply texture to STL using this code. Nothing is shown on the screen.
Code:
osg::Image *pImage = osgDB::readImageFile("icondata.png");
osg::Texture2D* pTex = new osg::Texture2D();
pTex->setTextureSize(400, 400);
pTex->setImage(pImage);
pTex->setFilter( pTex->MIN_FILTER,pTex->LINEAR);
pTex->setFilter( pTex->MAG_FILTER,pTex->LINEAR);
osg::ref_ptr<osg::Node> model = //load a STL file
model->getOrCreateStateSet()->setTextureAttributeAndModes(0, pTex);
Could you give me some hints to solve this problem.
Best regards,
NIE

Hi Nie,
iOS only support OpenGL ES, so you only can compile against GLES1 or 2, if you
want to do graphics on iOS then you have no choice beyond these. These two
versions of GLES are very different so you'll need to tackle both very
differently so you'll need to decide which route you want to go.

Hello Robert,
Thank you for replying.
I have checked osgtexture1D example and apply it to my source code(actually it is an iOS
app). Then I found that I have built osglib using GLES_1_available and GLES_2_available, which
makes texture1D not available in osg( err<<"texgen not supported" ). Is there
an alternative way to use texture1D, or I have to rebuild osglib with GLES_1_available and
GLES_2_available off? I think that I am not using GLES in my project.
Thank you.
NIE
