This article provides information about the Nvidia OpenGL 3.0 Beta Driver for Linux, a release specifically targeted at developers looking to explore and implement the new features offered by OpenGL 3.0 and GLSL 1.30. It outlines the key features, compatibility, limitations, and frequently asked questions surrounding this driver.
Introduction to OpenGL 3.0 and the Nvidia Beta Driver
OpenGL 3.0 marked a significant evolution in the graphics API landscape, introducing new functionalities and a more structured approach to graphics programming. This beta driver from Nvidia was designed to give developers early access to these advancements, allowing them to begin integrating OpenGL 3.0 features into their Linux-based applications.
The Nvidia OpenGL 3.0 Beta Driver for Linux is intended for developers. It’s crucial to understand that the OpenGL 3.0 and GLSL 1.30 features are not enabled by default.
Enabling OpenGL 3.0 Features
Unlike some driver installations, enabling OpenGL 3.0 within this Nvidia OpenGL 3.0 Beta Driver for Linux doesn’t require specific actions at the driver level. Instead, developers utilize the nvemulate utility, detailed at https://developer.nvidia.com/object/nvemulate.html, to activate the new functionalities. This approach provides fine-grained control over feature enablement, allowing developers to target specific OpenGL 3.0 capabilities as needed.
Hardware Compatibility
The Nvidia OpenGL 3.0 Beta Driver for Linux is compatible with a range of Nvidia graphics cards, primarily those based on the G80 architecture or newer. This includes:
Desktop:
- Quadro FX 370, 570, 1700, 3700, 4600, 4700×2, 5600
- GeForce 8000 series or higher; GeForce GTX 260, 280
Notebook:
- Quadro FX 360M, 370M, 570M, 770M, 1600M, 1700M, 2700M, 3600M, 3700M
- GeForce 8000 series or higher
It’s important to note that older hardware, such as NV3x, NV4x, and G7x based cards, are not supported by this driver for OpenGL 3.0 functionality.
Implemented Features and Limitations
This beta driver implements the entirety of GLSL 1.30 and OpenGL 3.0, with a few exceptions:
- Missing Functionality:
- One-channel (RED) and two-channel (RG) textures
- The Clearbuffer API
- Windowless rendering support (GPU affinity is suggested as an alternative)
- Forward-compatible context
- Debug Context
New Extensions Exposed
The driver exposes the following new extensions, providing access to additional functionalities:
OpenGL 2.1 extensions:
- ARB_vertex_array_object
- ARB_framebuffer_object
- ARB_half_float_vertex
OpenGL 3.0 extensions:
- WGL_create_context
- GLX_create_context
- ARB_draw_instanced
- ARB_geometry_shader4
- ARB_texture_buffer_object
Improvements Over Previous Releases
Compared to the earlier Windows beta driver release (177.89), this Linux version includes several enhancements:
- Linux Support: Brings identical OpenGL 3.0 and GLSL 1.30 functionality to the Linux platform, mirroring the Windows release.
- Mixed-Size Attachment Rendering: Allows rendering to a Framebuffer Object (FBO) with mixed-size attachments.
- VAO Improvements: Includes bug fixes and performance enhancements related to Vertex Array Objects (VAOs).
- EXT_texture_swizzle Support: Adds support for the
EXT_texture_swizzleextension, providing more flexible texture manipulation. - Transform Feedback Implementation: Implements missing functionality for transform feedback, a powerful feature for geometry processing.
- Bug Fixes: Addresses various other identified bugs, improving overall stability and reliability.
Accessing Specifications and Reporting Issues
The official OpenGL 3.0 and GLSL 1.30 specifications can be downloaded from the OpenGL registry: https://www.opengl.org/registry/.
For any bugs or issues encountered while using the driver, Nvidia encourages developers to file a bug report through their developer website: https://nvdeveloper.nvidia.com/.
OpenGL 3.0 on NVIDIA Hardware: Frequently Asked Questions
Nvidia provided a detailed FAQ to address common questions about OpenGL 3.0 implementation on their hardware. Here are some key points:
1) How to start using OpenGL 3.0 in code:
Applications must explicitly "opt-in" to use OpenGL 3.0 and later versions. This is done using the CreateContextAttribsARB function (for WGL and GLX, defined in the WGL/GLX_ARB_create_context extensions) to request a context that supports OpenGL 3.0 or later. If you continue using older context creation calls, you’ll get an OpenGL 2.1 context.
2) Deprecation and Functionality Removal:
OpenGL 3.0 introduced a deprecation and profile mechanism. Deprecation means a feature is marked for removal in a future version, but it’s not removed in OpenGL 3.0 itself. The OpenGL ARB provides a mechanism (profile or ARB-approved extension) for encapsulating functionality for specific markets.
3) Existing Application Compatibility:
Nvidia stated they had no plans to drop support for OpenGL 2.1 and earlier versions on existing and future hardware. Therefore, existing applications should continue to function as expected.
4) Hardware Support for OpenGL 3.0:
OpenGL 3.0 requires G80 or newer hardware. Older cards are not supported. See the hardware compatibility list above.
6) Future Removal of OpenGL Functionality:
Nvidia emphasized their commitment to supporting features relied upon by ISVs. They believe in minimizing disruption for developers and will leverage the profile/extension mechanism to continue supporting deprecated features in future OpenGL versions.
7) Performance of Deprecated Functionality:
Nvidia committed to providing full performance, support, and bug fixes for all features, including those on the deprecated list.
Conclusion
The Nvidia OpenGL 3.0 Beta Driver for Linux offered developers a valuable opportunity to explore and implement the new capabilities of OpenGL 3.0 and GLSL 1.30 on the Linux platform. While it had some limitations due to its beta status, it provided a crucial stepping stone for developers to prepare for the future of graphics programming with OpenGL. Remember to consult the official OpenGL registry and Nvidia’s developer website for the latest specifications, updates, and support resources.
