OpenGL 4.0 and 3.3: A Deep Dive

OpenGL (Open Graphics Library) is a cross-language, cross-platform API for rendering 2D and 3D vector graphics. It’s a cornerstone of modern graphics development, used in everything from video games to scientific visualization. The Nvidia GeForce Ion Graphics Notebook Drivers 197.44 bring significant updates to OpenGL support.

OpenGL 4.0: The Cutting Edge

OpenGL 4.0 represents a major step forward in graphics technology. To utilize the features of OpenGL 4.0 and GLSL 4.00, a Fermi-based Nvidia GPU is required. Fermi architecture introduced significant advancements in parallel processing and memory management, enabling the efficient execution of complex graphics algorithms.

OpenGL 4.0 introduces extensions such as:

ARB_texture_compression_bptc: Enhances texture compression for improved visual quality and reduced memory footprint.
EXT_shader_image_load_store: Allows shaders to directly load from and store to images, enabling more flexible and efficient rendering techniques.
EXT_vertex_attrib_64bit: Provides support for 64-bit vertex attributes, increasing precision and enabling more detailed models.
NV_gpu_shader5, NV_gpu_program5, NV_tessellation_program5: Nvidia-specific extensions that provide advanced shader capabilities and tessellation control.
NV_vertex_attrib_integer_64bit: Enables the use of 64-bit integer vertex attributes.
NV_shader_buffer_store: Allows shaders to directly access and modify buffer objects.

OpenGL 3.3: Broad Compatibility

OpenGL 3.3 offers a balance of modern features and broad hardware compatibility. The Nvidia GeForce Ion Graphics Notebook Drivers 197.44 support OpenGL 3.3 and GLSL 3.30 on a wider range of Nvidia GPUs, including:

Desktop:

Quadro FX 370, 570, 1700, 3700, 4600, 4700×2, 4800, 5600, 5800, Quadro VX200, Quadro CX
GeForce 8000 series or higher; Geforce G100, GT120, 130, 220, GTS 150, GTS 250, GT310, 320, 330, 340, GeForce GTX 260 and higher, any ION based products.

Notebook:

Quadro FX 360M, 370M, 570M, 770M, 1600M, 1700M, 2700M, 2800M, 3600M, 3700M, 3800M
GeForce 8000 series or higher

For OpenGL 2 capable hardware, the drivers provide new extensions:

ARB_texture_swizzle
ARB_sampler_objects
ARB_occlusion_query2
ARB_timer_query
ARB_explicit_attrib_location

These extensions are also incorporated into core OpenGL 3.3.

OpenGL and Deprecation: Understanding the Changes

The introduction of OpenGL 3.0 brought with it a deprecation mechanism, marking certain features for removal in future versions. While these features were not immediately removed in OpenGL 3.0, the OpenGL 3.1 specification did remove them. To address the need for both new functionality and continued support for older features, the ARB_compatibility extension was created. This extension re-introduced the removed functionality into core OpenGL 3.1.

Starting with OpenGL 3.2, the OpenGL ARB introduced two profiles: the "Core" profile and the "Compatibility" profile. The Core profile builds on top of OpenGL 3.1 (without ARB_compatibility) and does not support any deprecated features. The Compatibility profile builds on top of OpenGL 3.1 including ARB_compatibility, providing full support for all features, including deprecated ones. Both profiles are available in these Nvidia GeForce Ion Graphics Notebook Drivers 197.44. Nvidia recommends that developers create a Compatibility profile context to ensure backwards compatibility of existing OpenGL code.

Addressing Common Concerns: An OpenGL FAQ

Nvidia has addressed several common questions regarding OpenGL implementation on their hardware.

How to start using OpenGL 4: Applications must "opt-in" to use OpenGL 3.0 and later versions by using the CreateContextAttribsARB function (defined in the WGL/GLX_ARB_create_context extensions) to request a context that supports OpenGL 3 or 4. For OpenGL 3.2 and later, including OpenGL 4.0, it’s also necessary to specify whether the "Core" or "Compatibility" profile is desired.
The "old" context creation API (WGL/GLXCreateContext): While still functional, the new CreateContextAttribsARB API is strongly recommended for new code. The old API will create an OpenGL 4.0 Compatibility profile.
Nvidia’s future plans for OpenGL functionality: Nvidia has no plans to remove any features from OpenGL that their users rely on and fully supports the ARB_compatibility extension and Compatibility profile.
Compatibility of existing applications: All currently shipping applications will continue to work on Nvidia’s existing and future hardware.
Hardware support for OpenGL 3 and 4: OpenGL 3 requires G80 or newer hardware, while OpenGL 4 requires a Fermi GPU.
Performance of deprecated features: Nvidia will provide full performance and support for any feature on the deprecated list.
