485709f708 Moved GL2Extensions functionality into the include/osg/GLExtensions header and new GLExtensions object.
Moved the #defines into new include/osg/GLDefines
Converted all GL2Extensions usage to GLExtensions usage

9f13e2fcb9 From Lionel Lagarde, "Support for paging and shared PBO"
"The attached file contains:
- a per-context read counter in GLBufferObject::BufferEntry
- a global client counter in BufferData
- the glue between Texture* and Image client counter

to fix all occurrences of "macro's" and "paramter".

551d2b6479 From Ulrich Hertlein, "not sure how severe this is but I believe there's a bug in
Texture.cpp:applyTexImage2D_subload:

<code>
unsigned char* data = = (unsigned char*)image->data();
if (needImageRescale) {
 // allocates rescale buffer
 data = new unsigned char[newTotalSize];

 // calls gluScaleImage into the data buffer
}

const unsigned char* dataPtr = image->data();
// subloads 'dataPtr'

// deletes 'data'
</code>

In effect, the scaled data would never be used.

I've also replaced bits of duplicate code in Texture1D/2D/2DArray/3D/Cubemap/Rectangle
that checks if the texture image can/should be unref'd with common functionality in
Texture.cpp.

a79a8d30f9 Convesion of osg::notify to OSG_INFO etc. 2010-05-28 15:47:52 +00:00
Robert Osfield
47af634399 Refactored the way that osg::Image/ImageSequence manages the update callback that needs to be attached to Textures to make it possible to use the Image::update() mechansim in other subclasses from osg::Image.
To enable the automatic attachment of the required update callback to call osg::Image::update(..) subclasses from osg::Image will
need to implement the osg::Image::requestUpdateCall() and return true, and implement the osg::Image::update(NodeVisitor*) method to recieve the update call during the update traversal.

65c6fdd8ca Added check for image compatibility with existing texture object, releasing the existing texture object in cases when the new image size/pixel format is not compatible. 2009-12-08 17:33:01 +00:00

b199a334d9 Introduced OSG_GL*_FEATURES macros defined in include/GL that are set to 0 or 1 according to what the assocoated version of GL is compiled against.
Removed EXT postfix of FrameBufferObject functions, and added support for checking non EXT versions frame buffer object GL functions.

Introduced usage of OSG_GL*_FEATURES to avoid some #if #else #endif code blocks.

Using a submissions from Paul Martz as a guide added perliminary GL3 support to a range of OSG classes

850034ab75 Moved the _textureObjectBuffer assignment to after the imagery has been download to avoid crashes under multi-threaded compile of texture objects (was causing a crash with 3D Textures, but is something that would happen with other Texture types as well.) 2008-07-16 13:23:58 +00:00

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.

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.

eac3dc1963 From Paul Melis, "Here is a list of fixes to misspelled APIs. Unfortunately, more than one
of these are public APIs and therefore will break linkage to existing
shared libraries."

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.
