ec63cfd930 From Mathias Froehlich, "small addition to osg::Texture to include all possible depth test variants for
the shadow depth comparison."

8677c4d6d6 From Michael Platings, "On nvidia cards mipmap generation for non-power-of-two textures with
GL_GENERATE_MIPMAP_SGIS is very slow (over half a second for a 720*576
texture). However, glGenerateMipmapEXT() performs well (16ms for the
same texture), so I have modified the attached files to use
Texture::generateMipmap() if glGenerateMipmapEXT is supported, instead
of enabling & disabling GL_GENERATE_MIPMAP_SGIS."

Notes, from Robert Osfield, I've tested the out of the previous path using
GL_GENERATE_MIPMAP_SGIS and non power of two textures on NVidia 7800GT and
Nvidia linux drivers with the image size 720x576 and only get compile times
of 56ms, so the above half second speed looks to be a driver bug.  With
Muchael's changes the cost goes done to less than 5ms, so it's certainly 
an effective change, even given that Michael's poor expereiences with
GL_GENERATE_MIP_SGIS do look to be a driver bug.

ff565128af Introduced new osg::discardDeletedOpenGLObjects() methods, and usage of it in
GrpahicsContext::close() to handle cases where deletingOpenGLObjects is no possible,
such as when GraphicsWindowEmbedded is used.

c51e893ba4 Changed the isTextureIntegerSupported method so that it no longer has the EXT entry in it
for forward compatability reasons.

5e83ae4821 From Art Trevs, "Features of the patch are:
- Implementation of integer textures as in EXT_texture_integer

- setBorderColor(Vec4) changed to setBorderColor(Vec4d) to pass double values
as border color. (Probably we have to provide an overloading function to
still support Vec4f ?)

- new method Texture::getInternalFormatType() added. Gives information if the
internal format normalized, float, signed integer or unsigned integer. Can
help people to write better code ;-)

"

Futher changes to this submission by Robert Osfield, changed the dirty mipmap
flag into a buffer_value<> vector to ensure safe handling of multiple contexts.

409cdd0b28 Intoduced a new setGLExtensions template method to do a copy of void* pointer to
local function pointer to avoid compiler warnings related to case void*.

Moved various OSG classes across to using setGLExtensions instead of getGLExtensions,
and changed them to use typedef declarations in the headers rather than casts in
the .cpp.

Updated wrappers

c747c7dbd6 Moved defined from Texture2DArray into Texture 2007-09-07 13:25:28 +00:00

c7a72c8435 From Art Tevs,
"A new texture class Texture2DArray derived from
Texture extends the osg to support the new
EXT_texture_array extensions. Texture arrays provides
a feature for people interesting in GPGPU programming.


Faetures and changes:

- Full support for layered 2D textures.

- New uniform types were added (sampler2DArray)

- FrameBufferObject implementation were changed to
support attaching of 2D array textures to the
framebuffer

- StateSet was slightly changed to support texture
arrays. NOTE: array textures can not be used in fixed
function pipeline. Thus using the layered texture as a
statemode for a Drawable produce invalid enumerant
OpenGL errors.

- Image class was extended to support handling of
array textures

Tests:
I have used this class as a new feature of my
application. It works for me without problems (Note:
Texture arrays were introduced only for shading
languages and not for fixed function pipelines!!!).
RTT with Texture2DArray works, as I have tested them
as texture targets for a camera with 6 layers/faces
(i.e. replacement for cube maps). I am using the array
textures in shader programming. Array textures can be
attached to the FBO and used as input and as output."

579700bedf From Mike Wittman, " noticed that some type references of osg::Drawable::AttributeFunctor, osg::Drawable::ConstAttributeFunctor, and osg::StateAttribute::ModeUsage in osg and osgSim were not being properly reflected in osgIntrospection. This appears to be due to Doxygen not handling nested types from superclasses if they're not qualified when referenced in subclasses.
These changes add the necessary superclass type qualification so that Doxygen now recognizes the references."

be60b32add Fixed texture optimization problem associated with mixing already compiled scene graphs - resulting
in incorrect texture assignment.  Solution was to a compareTextureObjects() test to the Texture*::compare(..) method that
the osgUtil::Optimizer::StateSetVisitor uses to determine uniqueness.

53e075f78b From Brad Colbert/Robert Osfield: added s/getSourceFormat and s/getSourceType to osg::Texture
along with support for this Texture1D, 2D, 3D, TextureCubeMap and TextureRectangle.  The
new SourceFormat and SourceType parameters are only used when no osg::Image is assigned to
an osg::Texture, and main use is for render to texture effects.

Added support for --hdr option in osgprerender, which utilises the new Texture::setSourceFormat/Type() methods.

a1bda0dab8 Added support for per context extension string.
Note, this required adding a unsigned int context ID to the osg::isGLUExtensionSupported(,)
and osg::isGLExtensionSupported(,) functions.  This may require reimplementation
of end user code to accomodate the new calling convention.
