GL_APPLE_flush_buffer_range
(Specification)
APPLE_flush_buffer_range expands the buffer object API to allow greater

System: Mac OS X v10.4.x "Tiger" and later
Renderers: Pending
|
|
|

|
|
|
GL_ARB_pixel_buffer_object
(Specification)
This extension expands on the interface provided by the
ARB_vertex_buffer_object extension (and later integrated into OpenGL
1.5) in order to permit buffer objects to be used not only with vertex
array data, but also with pixel data. The intent is to provide more
acceleration opportunities for OpenGL pixel commands.
System: Mac OS X v10.4.x "Tiger" and later
Renderers: Pending
|
|
|
GL_ARB_point_sprite
(Specification)
Applications such as particle systems have tended to use OpenGL quads
rather than points to render their geometry, since they would like
to use a custom-drawn texture for each particle, rather than the
traditional OpenGL round antialiased points, and each fragment in
a point has the same texture coordinates as every other fragment.
System: Mac OS X v10.4.x "Tiger" and later
Renderers: Pending
|
|
|
GL_ARB_shader_objects
(Specification)

Renderers: Pending
|
|
|
GL_ARB_texture_float
(Specification)
This extension adds texture internal formats with 16- and 32-bit
floating-point components. The 32-bit floating-point components
are in the standard IEEE float format. The 16-bit floating-point
components have 1 sign bit, 5 exponent bits, and 10 mantissa bits.
Floating-point components are clamped to the limits of the range
representable by their format.
System: Mac OS X v10.4.x "Tiger" and later
Renderers: Pending
|
|
|
GL_ARB_texture_non_power_of_two
(Specification)
Conventional OpenGL texturing is limited to images with
power-of-two dimensions and an optional 1-texel border.

for the 1D, 2D, cube map, and 3D texture targets.
System: Mac OS X v10.4.8 "Tiger" and later
Renderers: Pending
|
|
|
GL_ARB_texture_rectangle

and an optional 1-texel border. The ARB_texture_rectangle extension
adds a new texture target that supports 2D textures without requiring
power-of-two dimensions.

Renderers: Pending
|
|
|
GL_ARB_vertex_buffer_object
(Specification)

(especially vertex array data) to be cached in high-performance
graphics memory on the server, thereby increasing the rate of data
transfers.
System: Mac OS X v10.4.x "Tiger" and later
Renderers: Pending
|
|
|
GL_ARB_vertex_shader
(Specification)
This extension adds programmable vertex level processing to OpenGL. The
application can write vertex shaders in a high level language as defined
in the OpenGL Shading Language specification. The language itself is not
discussed here. A vertex shader replaces the transformation, texture
coordinate generation and lighting parts of OpenGL, and it also adds
texture access at the vertex level. Furthermore, management of vertex
shader objects and loading generic attributes are discussed. A vertex
shader object, attached to a program object, can be compiled and linked
to produce an executable that runs on the vertex processor in OpenGL.
This extension also defines how such an executable interacts with the
fixed functionality vertex processing of OpenGL 1.4.
System: Mac OS X v10.4.3 "Tiger" and later
Renderers: Pending
|
|
|
GL_EXT_blend_equation_separate
(Specification)
EXT_blend_func_separate introduced separate RGB and alpha blend
factors. EXT_blend_minmax introduced a distinct blend equation for
combining source and destination blend terms. (EXT_blend_subtract &
EXT_blend_logic_op added other blend equation modes.) OpenGL 1.4
integrated both functionalities into the core standard.
System: Mac OS X v10.4.x "Tiger" and later
Renderers: Pending
|
|
|
GL_EXT_depth_bounds_test
(Specification)
This extension adds a new per-fragment test that is, logically,
after the scissor test and before the alpha test. The depth bounds
test compares the depth value stored at the location given by the
incoming fragment's (xw,yw) coordinates to a user-defined minimum
and maximum depth value. If the stored depth value is outside the
user-defined range (exclusive), the incoming fragment is discarded.
System: Mac OS X v10.4.x "Tiger" and later
Renderers: Pending
|
|
|
GL_EXT_framebuffer_blit
(Specification)
This extension modifies EXT_framebuffer_object by splitting the
framebuffer object binding point into separate DRAW and READ
bindings. This allows copying directly from one framebuffer to
another. In addition, a new high performance blit function is
added to facilitate these blits and perform some data conversion
where allowed.
System: Mac OS X v10.4.x "Tiger" and later
Renderers: Pending
|
|
|
GL_EXT_framebuffer_object
(Specification)
This extension defines a simple interface for drawing to rendering
destinations other than the buffers provided to the GL by the
window-system.

Renderers: Pending
|
|
|
GL_EXT_geometry_shader4
(Specification)
EXT_geometry_shader4 defines a new shader type available to be run on the
GPU, called a geometry shader. Geometry shaders are run after vertices are
transformed, but prior to color clamping, flat shading and clipping.
System: Mac OS X v10.4.10 "Tiger" and later
Renderers: GeForce 8600M through 10.5.1, and all renderers on 10.5.2 and later.
|
|

Renderers: Pending
|
|
|
GL_EXT_gpu_shader4
(Specification)

stencil buffers into one buffer, often with 24 bits of depth
precision and 8 bits of stencil data.

Renderers: Pending
|
|
|
GL_EXT_separate_specular_color
(Specification)
This extension adds a second color to rasterization when lighting is
enabled. Its purpose is to produce textured objects with specular
highlights which are the color of the lights. It applies only to
rgba lighting.
System: Mac OS X v10.4.x "Tiger" and later
Renderers: Pending
|
|
|
GL_EXT_texture_compression_dxt1
(Specification)
Support of EXT_texture_compression_s3tc is attractive for OpenGL-ES
implementations because it provides compressed textures that allow
for significantly reduced texture storage. Reducing texture storage is
advantageous because of the smaller memory capacity of many embedded
systems compared to desktop systems. Smaller textures also provide a
welcome performance advantage since embedded platforms typically provide
less performance than desktop systems. S3TC compressed textures
are widely supported and used by applications. The DXT1 format is
used in the vast majority of cases in which S3TC compressed textures
are used.
System: Mac OS X v10.4.x "Tiger" and later
Renderers: Pending

|
|
GL_EXT_texture_mirror_clamp
(Specification)
EXT_texture_mirror_clamp extends the set of texture wrap modes to
include three modes (GL_MIRROR_CLAMP_EXT, GL_MIRROR_CLAMP_TO_EDGE_EXT,
GL_MIRROR_CLAMP_TO_BORDER_EXT) that effectively use a texture map
twice as large as the original image in which the additional half
of the new image is a mirror image of the original image.
System: Mac OS X v10.4.x "Tiger" and later
Renderers: Pending
|
|
|
GL_EXT_texture_sRGB
(Specification)
The sRGB color space is based on typical (non-linear) monitor
characteristics expected in a dimly lit office. It has been
standardized by the International Electrotechnical Commission (IEC)
as IEC 61966-2-1. The sRGB color space roughly corresponds to 2.2
gamma correction.

GL_ARB_fragment_program
(Specification)
Exposes a significant degree of per-fragment programmability for computing fragment parameters.
