Hi everyone.
I'm experiencing an issue with texture images. I am using line segment
intersectors in a manner similar to picking. With a couple of models, the
texture retrieving algorithm works fine, however, with one model it fails. This
is the extract of the code:
Code:
osg::Drawable *collisionDrawable = intersection.drawable.get();
osg::StateSet *collisionStateSet = collisionDrawable ?
collisionDrawable->getStateSet() : null;
osg::Geometry *collisionGeometry = collisionDrawable ?
collisionDrawable->asGeometry() : null;
...
osg::Texture* texture = dynamic_cast<osg::Texture*>
(collisionStateSet->getTextureAttribute(0, osg::StateAttribute::TEXTURE));
osg::Image *textureImage = texture ? texture->getImage(osg::Material::FRONT) :
null;
the textureImage equals to NULL after this sequence, while the texture does
not. so why does the texture->getImage() method not return expected texture ? I
checked the model, it seems to be all right. this is an example
Code:
...
Geode {
...
num_drawables 1
Geometry {
DataVariance STATIC
StateSet {
DataVariance STATIC
...
textureUnit 0 {
GL_TEXTURE_2D ON
Texture2D {
file ".\\textures\\102.jpg"
wrap_s REPEAT
wrap_t REPEAT
wrap_r CLAMP
min_filter LINEAR_MIPMAP_LINEAR
mag_filter LINEAR
maxAnisotropy 1
borderColor 0 0 0 0
borderWidth 0
useHardwareMipMapGeneration TRUE
unRefImageDataAfterApply TRUE
internalFormatMode USE_IMAGE_DATA_FORMAT
resizeNonPowerOfTwo TRUE
shadowComparison FALSE
shadowCompareFunc GL_LEQUAL
shadowTextureMode GL_LUMINANCE
}
TexEnv {
UniqueID TexEnv_4
mode MODULATE
}
}
}
the other model, where it works, looks alike, when exported to osg format. so
why is it, that for this model, the algorithm fails ? can anyone tell?
Thank you very much, and i mean it, for anything useful!
Cheers,
Andrey
