Hi, im reading a openGl 4 tutorial that say that I have to upgrade my video card drivers (Nvidia or Ati) for get the libraries, the problem is that im learning to code in a netbook, so the cuestion is: Is posible to use the openGl libraries in a netbook?

OpenGL will run on almost anything, but the feature level will vary. Intel based netbooks report as OpenGL 1.4 I think but support extensions that almost make them OpenGL 2 compatible (most of the missing extensions are multisample related afair). I think some of the AMD based netbooks even had OpenGL4 support but don't quote me on that.

Yes, it's possible.  I've an Acer Aspire One that I bring with me when travelling and it comes with a Radeon 6250 supporting GL4.2 and even some 4.3 extensions.  It's not particularly fast - maybe good for up to and including a Quake 3 level of scene complexity - but the full shader/etc capabilities are there.

 

I don't know what the current state of play is with Intel netbook graphics, but if you can get something with a HD3000/HD4000 you'll have good enough GL3.x capabilities; again without being particularly fast.

 

In both cases you'll get better D3D support than GL support; particularly with Intel graphics where anything reasonably recent should support D3D10 or 11, but have GL support that's lagging a few versions behind.

 

In general the main bottleneck on these is going to be your CPU; for programming that's going to affect compile times, program startup times, IDE usage, etc.  However, and if you can afford it, replacing the hard disk with an SSD can be a useful investment - not as good as with a more mainstream machine (that CPU bottleneck is just too much) but it does help make general usage a bit more pleasant.

I am coding for OpenGL 3.3 on my netbook, which has an ION 2 (GT210 based I think?) but ION LE netbooks also support OpenGL 3.3 (GeForce 9400M based).

 

Pretty much any AMD netbook (AMD CPU + AMD GPU combo) will give you at least OpenGL 3 support.

 

Aaaand for Intel, no idea. Its always hit n' miss from what I hear.

I can report for my notebook containing HD 5470, that using OpenGL (with recent drivers, I get all 4.2 features, and most of the 4.3 features) is quite fine. Of course the speed is like 15 times slower compared to HD 6770.

 

Anyways in my opinion it is also good to run your project on notebook GPU with good framerate (at least 30) on low/moderate details, it will make your project well optimized, and possible to run for people using notebooks (which is always good, as they also might buy it).

OpenGL 4 will probably be out of reach (unless your netbook happens to be AMD based), but OpenGL 3.3 may be possible, otherwise you'd be limited to OpenGL 2.1(in which case, I'd suggest possibly using Direct3D instead). It really depends on the CPU/GPU combination found in your particular netbook.....

Hold on. Let OP say what graphics card he's got.

If it is GMA3150 (like in my netbook), then he should say farewell to shaders. It is hard to say that GMA3150 supports even GL1.5, and it is light-years away from the GL 2.0. There is only 2 fragmet shader units, and vertex shader is supported only in software (for D3D). There is an interface to some prehistoric version of shaders, but there is no support even for GLSL 1.x.

At least under linux I can use GLSL 1.0 on my Atom N550 netbook (which has said GM3150). Performance is obviously questionable at best.

Wow! That's a miraculous achievement of GM3150. smile.png

Let's remember, GL2.0 requires GLSL 1.1 (or tu be more precise 1.10.xx).

GLSL 1.0 is a predecessor of GLSL exposed in the time of GL1.4 to announce arrival of new era. The interface to shaders is not the same as in GLSL 1.1 and other successors. That's what I meant when said ancient  interface.

The Intel 3150 is actually a D3D9/SM3 class part, so any capability failing in GL land is due to Intel's notorious driver quality.  As was mentioned upthread, if the OP is using one of these then D3D is going to be a much better option than GL for accessing semi-modern features.

      The Khronos™ Group, an open consortium of leading hardware and software companies, announces from the SIGGRAPH 2017 Conference the immediate public availability of the OpenGL® 4.6 specification. OpenGL 4.6 integrates the functionality of numerous ARB and EXT extensions created by Khronos members AMD, Intel, and NVIDIA into core, including the capability to ingest SPIR-V™ shaders.
      SPIR-V is a Khronos-defined standard intermediate language for parallel compute and graphics, which enables content creators to simplify their shader authoring and management pipelines while providing significant source shading language flexibility. OpenGL 4.6 adds support for ingesting SPIR-V shaders to the core specification, guaranteeing that SPIR-V shaders will be widely supported by OpenGL implementations.
      OpenGL 4.6 adds the functionality of these ARB extensions to OpenGL’s core specification:
      GL_ARB_gl_spirv and GL_ARB_spirv_extensions to standardize SPIR-V support for OpenGL GL_ARB_indirect_parameters and GL_ARB_shader_draw_parameters for reducing the CPU overhead associated with rendering batches of geometry GL_ARB_pipeline_statistics_query and GL_ARB_transform_feedback_overflow_querystandardize OpenGL support for features available in Direct3D GL_ARB_texture_filter_anisotropic (based on GL_EXT_texture_filter_anisotropic) brings previously IP encumbered functionality into OpenGL to improve the visual quality of textured scenes GL_ARB_polygon_offset_clamp (based on GL_EXT_polygon_offset_clamp) suppresses a common visual artifact known as a “light leak” associated with rendering shadows GL_ARB_shader_atomic_counter_ops and GL_ARB_shader_group_vote add shader intrinsics supported by all desktop vendors to improve functionality and performance GL_KHR_no_error reduces driver overhead by allowing the application to indicate that it expects error-free operation so errors need not be generated In addition to the above features being added to OpenGL 4.6, the following are being released as extensions:
      GL_KHR_parallel_shader_compile allows applications to launch multiple shader compile threads to improve shader compile throughput WGL_ARB_create_context_no_error and GXL_ARB_create_context_no_error allow no error contexts to be created with WGL or GLX that support the GL_KHR_no_error extension “I’m proud to announce OpenGL 4.6 as the most feature-rich version of OpenGL yet. We've brought together the most popular, widely-supported extensions into a new core specification to give OpenGL developers and end users an improved baseline feature set. This includes resolving previous intellectual property roadblocks to bringing anisotropic texture filtering and polygon offset clamping into the core specification to enable widespread implementation and usage,” said Piers Daniell, chair of the OpenGL Working Group at Khronos. “The OpenGL working group will continue to respond to market needs and work with GPU vendors to ensure OpenGL remains a viable and evolving graphics API for all its customers and users across many vital industries.“
      The OpenGL 4.6 specification can be found at https://khronos.org/registry/OpenGL/index_gl.php. The GLSL to SPIR-V compiler glslang has been updated with GLSL 4.60 support, and can be found at https://github.com/KhronosGroup/glslang.
      Sophisticated graphics applications will also benefit from a set of newly released extensions for both OpenGL and OpenGL ES to enable interoperability with Vulkan and Direct3D. These extensions are named:
      GL_EXT_memory_object GL_EXT_memory_object_fd GL_EXT_memory_object_win32 GL_EXT_semaphore GL_EXT_semaphore_fd GL_EXT_semaphore_win32 GL_EXT_win32_keyed_mutex They can be found at: https://khronos.org/registry/OpenGL/index_gl.php
      Industry Support for OpenGL 4.6
      “With OpenGL 4.6 our customers have an improved set of core features available on our full range of OpenGL 4.x capable GPUs. These features provide improved rendering quality, performance and functionality. As the graphics industry’s most popular API, we fully support OpenGL and will continue to work closely with the Khronos Group on the development of new OpenGL specifications and extensions for our customers. NVIDIA has released beta OpenGL 4.6 drivers today at https://developer.nvidia.com/opengl-driver so developers can use these new features right away,” said Bob Pette, vice president, Professional Graphics at NVIDIA.
      "OpenGL 4.6 will be the first OpenGL release where conformant open source implementations based on the Mesa project will be deliverable in a reasonable timeframe after release. The open sourcing of the OpenGL conformance test suite and ongoing work between Khronos and X.org will also allow for non-vendor led open source implementations to achieve conformance in the near future," said David Airlie, senior principal engineer at Red Hat, and developer on Mesa/X.org projects.

      Hi,
      I have an OpenGL application but without possibility to wite own shaders.
      I need to perform small VS modification - is possible to do it in an alternative way? Do we have apps or driver modifictions which will catch the shader sent to GPU and override it?

      Does sync be needed to read texture content after access texture image in compute shader?
      My simple code is as below,
      glUseProgram(program.get());
      glBindImageTexture(0, texture[0], 0, GL_FALSE, 3, GL_READ_ONLY, GL_R32UI);
      glBindImageTexture(1, texture[1], 0, GL_FALSE, 4, GL_WRITE_ONLY, GL_R32UI);
      glDispatchCompute(1, 1, 1);
      // Does sync be needed here?
      glUseProgram(0);
      glBindFramebuffer(GL_READ_FRAMEBUFFER, framebuffer);
      glFramebufferTexture2D(GL_READ_FRAMEBUFFER, GL_COLOR_ATTACHMENT0,
                                     GL_TEXTURE_CUBE_MAP_POSITIVE_X + face, texture[1], 0);
      glReadPixels(0, 0, kWidth, kHeight, GL_RED_INTEGER, GL_UNSIGNED_INT, outputValues);
       
      Compute shader is very simple, imageLoad content from texture[0], and imageStore content to texture[1]. Does need to sync after dispatchCompute?
