[osg-users] OpenSceneGraph-3.6.3 release candidate 2 tagged

[Glenn Waldron]

Robert,
Transparency wasn't an issue (that was a missing GL_BLEND) but there are a
couple other interesting things I discovered with texture arrays:


1) After loading a GIF, I had to manually call
image->setInternalTextureFormat(GL_RGBA8), otherwise I get this message and
a blank texture:

Warning: Texture2DArray::applyTexImage2DArray_subload(..) given image do
have wrong dimension or internal format.

The original internal texture format was "4" which doesn't appear to be
legal even for glTexImage; perhaps glTexStorage is being more strict.


2) When using the LINEAR_MIPMAP_LINEAR minfilter, along with calling
tex->setResizeNonPowerOfTwoHint(false), the image appears black and I see
this message:

Warning: detected OpenGL error 'invalid operation' at
StateSet::compileGLObejcts() compiling texture attribute Texture2DArray.


Again, these may just be glTexStorage strictly enforcing things that
glTexImage was lenient about.
