Limits of shader OpenGL ES 2 (SGX 540)?

• OpenGL 2.0 and Shader Model 3.0

  After the purchase of Photoshop CS6 Extended because she's amazing 3D options, I realized my video card sucked because it's a CSU and not a GPU as required.

  Then I looked at what the requirements are to enable the GPU options and he said deserves an OpenGL 2.0 and Shader Model 3.0.

  I was looking for a video card that corresponds exactly to that without result (I live in a country the size of a peanut that doesn't sell a 2.0 and 3.0).

  But I found templates 5.0 shaders and OpenGL 4.1 and I wanted to know if it is acceptable also.

  OpenGL 2.0 and Shader Model 3.0 minimum requirements and if I can go higher?

  Or Photoshop Extended will not allow this GPU option if I go above Shader Model 3.0 and OpenGL 2.0 requested?

  Thank you very much!!!

  These are minimium requirements.  Also recommend a minimum of 1 GB of VRAM if 3D.

  Here is a site that class video cards.  A rank of 1000 is all excellent and about what's necessary.  http://www.videocardbenchmark.NET/

• BPS dialogues seem to stop working after the initialization of the OpenGL

  In the following example (the main.c to GLES20Template), if the call to show_alert (taken from the example of the dialog box) is performed before the call to bbutil_init_egl, we see a dialog box.  Otherwise, we do not see a dialog box (or an error message explaining what we did wrong).  That passed?

  OpenGL is not compatible with BPS?

  Anyone know how to get the dialogs BPS works in an application that uses OpenGL?

  then another

  I have the latest Nvidia driver. Anyway to fix this? Or I have to wait for Adobe support my GPU?
  

  I'd suggest ditching forced the C4D and ray traced rendering engine instead of use: Details of CINEMA 4 d with After Effects integration

  I mean, it's more powerful and it's free!

  If you absolutely need to use ray-traced rendering engine, what are you trying to use it on? Try it with only a layer of simple form you need to do 3d just to eliminate the problems of others, possibly complications, a project. What CC 2014 version are you running? 13.1? 13.2?

  Don't forget, Adobe is never going to add to the list supported for rendering engine raytraced as they develop is more this feature.

• Error of Minecraft OpenGL on Satellite L650 - 1 M 8

  Hey guys, I hope you can help me.
  
  So I have a Toshiba Satellite L650 - 1 M 8 Mobile and last year, I bought and downloaded Minecraft for play.
  At the opening, I get the classic error of OpenGL.
  I tried for hours searching the web for solutions to this problem that I badly want to play what I paid for.
  
  I contacted Mojang on this issue, they cannot help because of different systems in the world, he is present to diversify for them, so that they are limited to billing and account. I have read several discussions on this issue and do not yet have a solution.
  
  Recently, I saw a thread on the forums of Toshiba someone fixed it for their kids to play, but they are computer laptop was a different model to mine.
  
  My graphics card is Intel(r) HD Graphics, there is no option for the display driver in Device Manager. This has been updated with the latest version of the Toshiba support, as well as my version of Java later.
  
  Please help, thanks.

  Try the Intel display driver that you can download from the Intel page.

  Additional note: there is already a thread on this topic:
  http://forums.computers.Toshiba-Europe.com/forums/thread.jspa?threadID=70080

  So it of not necessary to open new discussions on the same theme.

• Satellite A350-13 b - OpenGL and Radeon HD3650

  Hello

  My laptop is the Satellite A350-13 b with ATI Mobility Radeon HD3650.

  I found that I have OpenGL 1.1 (7/7) and partially 1.2 (1/8).

  I installed the latest drivers from ATI, modded with Mobility Modder site (also tried drivers from the Toshiba website - no results).

  I found that the modded drivers require OpenGL patch to make it work.

  Must be added:

  HKLM\Software\Microsoft\Windows NT\CurrentVersion\OpenGLDrivers\ati2dvag
  "Version" = "2" REG_DWORD %
  'DriverVersion' = '1' REG_DWORD %
  'Flags' = '1' REG_DWORD %
  "Dll"="atioglxx.dll" REG_SZ %

  But after he OpenGL Extensions Viewer see values (1.1 and 1.2).

  How is it possible to check the highest available version OpenGl and operate?

  I have a file called atioglxx.dll in Windows\System32 and registry entries mentioned above, but OpenGL Extensions Viewer says:

  No support from flange edge texture
  This feature adds control for edge clamping texel filtering. Some programs may not properly making the textures (black line border).

  No support for vertex program
  This function allows programming of vertex (equivalent to DX8 Vertex Shader). Some current or future OpenGL programs may require this functionality.

  No support fragment program
  This feature allows programmatically pixels (equivalent to DX9 Pixel Shader). Some current or future OpenGL programs may require this functionality.

  No OpenGL Shading Language support
  This can break compatibility for applications using by pixel shading.

  No support Frame buffer objects
  This can break compatibility for applications that use the rendering to texture functions.

  Some found texture units
  This can slow down some applications using fragment programs or extended texture mapping.

• QT and OpenGL not made

  I have implemented the example in the SDK of 4.8 Qt under opengl/cube.

  http://Qt.Gitorious.org/Qt/Qt/trees/4.8/examples/OpenGL/cube

  I have modified so that it works on the PlayBook (that is, do not use QWindow).

  It runs great on Ubuntu in Qt Creator. Cross-compile for the PlayBook just fine and I can load it on the unit and run it, but it is not working properly.

  Namely, it simply display a blank screen of white that becomes black when I press on it. You will notice that there are a few qDebug()< calls="" in="" the="" initializegl()="" function="" call.="" i="" added="" some="" qmessagebox="" calls="" instead="" to="" see="" if="" these="" were="" being="" reached,="" and="" it="" seems="" they="" are.="" no="" idea="" if="" the="" other="" functions="" are="" being="" completed="" correctly,="" still="" looking="" into="">

  Anyone have any ideas of what I'm missing here? Is there a way to actually debug the program, so I can find the questions myself?

  It turns out that it was a problem with the repetition of the texture of OpenGL ES 2.0. Namely:

  // Wrap texture coordinates by repeating
      // f.ex. texture coordinate (1.1, 1.2) is same as (0.1, 0.2)
      glTexParameterf(GL_TEXTURE_2D, GL_TEXTURE_WRAP_S, GL_REPEAT);
      glTexParameterf(GL_TEXTURE_2D, GL_TEXTURE_WRAP_T, GL_REPEAT);
  

  Is not allowed. GL_REPEAT cannot be used with textures NPOT (power of two) in OpenGL ES 2.0. Instead, you must attach to the edge, or to implement in your fragment shader.

  // Wrap texture coordinates by repeating
      // f.ex. texture coordinate (1.1, 1.2) is same as (0.1, 0.2)
      glTexParameterf(GL_TEXTURE_2D, GL_TEXTURE_WRAP_S, GL_CLAMP_TO_EDGE);
      glTexParameterf(GL_TEXTURE_2D, GL_TEXTURE_WRAP_T, GL_CLAMP_TO_EDGE);
  

  Works fine now, EXCEPT that, when the application starts, it starts with a blank space where the OpenGL is rendered. Once the user clicks on it, it draws perfectly. No idea why this is the case.

• openGL 2.0 with jpeg textures

  Hi devs,

  I have a problem texturing a plane with textures with opengl 2.0. I am able to make the aircraft with colors, but as soon as I try to apply textures, I'm not. Instead, I see a shaded gray screen. So I guess that the vertices of the geometry and the viewport, etc. are correct, but something wrong with the application of textures. Does anyone have a sample code snippet to bind the texture on a plane using opengl 2.0? I want to use the triangle strip.

  Here are the steps I used to create a simple plan with a texture

  -Once I've created the foreign window and initiated openGL.

  -This is my plane vertices and texture coordinates

• Having trouble getting an updated driver at the level of OpenGL 3.0

  I have what is called "integrated graphics" IE graphics card Intel (r) HD on a G6950 processor. Level OpenGL display is 2.1 but I want to run some new SW that requires 3.0 (I'm not a 'gamer', it's BASIC SOFTWARE ENGINEERING). If I ask Microsoft to update my driver he says that everything is up-to-date, if I ask Intel driver update, it indicates a higher number release exists, but for reasons that I do not understand that she refuses to install it and when I called them, they said that they didn't think that they had a "duty" to support the higher level! I understand that I COULD buy and install a 'real' graphics card (the two slots are apparently empty right now) but I do not understand, the on-board system is not THAT bad and the graphical utility shows he did 12 cores - how much should I I need a basic system? I mean I don't think that's the problem of Microsoft really everything, but if it should not be possible to help all around it's much better than this? Only 5 years of the system, I've owned previous systems a lot longer! Besides if I have a third graphics card, on what basis should I expect to support their product that is BETTER THAN the Intel? (I guess it would be the problem of Microsoft if the deficit were to the DirectX level?) And where in the docs for a possible card do I know what level THEY are "ready to support"? It's really blow my mind...

  The graphics Intel(r) HD on a G6950 processor card is limited to the Open GL 2.1.

  It is compatible with DX10 but not DX11.

  It is a hardware limitation. There is nothing that can be done to correct this.

  You may well have owned systems that were older than 5 years earlier, but didn't have never been

  facing material limitations like this, but 5 years is, unfortunately, a lot of time in the years of dog/computer. Especially with graphics.

  Apparently your cpu was released in 2010, and I think she's a first version of the most recent

  Graphics card Intel HD, which is integrated into the cpu vs a chip on the motherboard, but is a little too

  early to Open GL 3.0.

  «.. . If I get a third party graphics card, on what basis should I expect to support their product is BETTER THAN the Intel? »

  Intel is not a graphics support period long. It is at least partly due to the fact that drivers is modified according to motherboards, which requires that download you the drivers from the

  card mother mfg if you want a guarantee of stability and the card mother mfg and laptop mfg

  often provide an update of the driver after one or maybe two years.

  -However, Intel updates often drivers for their graphics for a longer period than the card mother mfg, so that you can sometimes download latest drivers for graphics card intel directly from

  Intel or even through updates of Windows (the "optional" section) and have no problem.

  MFG of dedicated graphics cards tend to support their cards with the new drivers for more

  periods ie - Nvidia drivers latest still support graphics cards, released in June 2010.

  They always supported the gpu in their pilots in July 2014 which have been published in ' 05

  Note that while pilots can still support these 'old' cards, there is little or no benefit

  update the drivers for the graphics over three years and "optimizations".

  more addressing the most recent series, in particular cards the last series (in large part because)

  the 'old' series was optimized to the maximum).

  Which brings back us to the motherboard. You may need an update to the BIOS of your motherboard

  to be able to recognize a current or previous series dedicated graphics card (with Nvidia is

  the 700 and 900 series cards).

  This is assuming that your motherboard has a recent enough BIOS update available.

  Then we come to the part concerning power. You should also check the power supply

  Watts/amps to run a card dedicated graphics and loose power supplies

  ability to produce current and complete stability current with age.

  It is less of a problem if you were to add a graphics card down range, as they can often operate

  off the PCIe slot, without electrical connection additional required.

  -Short answer...

  If you need this software for professional (or use the 'new' version at all).

  You can get a more recent machine, if you want to avoid complications.

  And with a new machine, you will not need to use a dedicated graphics card. The new Intel HD graphics

  are much more powerful than what you currently have, especially on the i5 cpu.

  -My 'old' i5 3570 cpu with HD 400 in 2012 can be exhausting to Open GL 4.0.
  In my view, are also capable of up to Open GL 4.0 i3 with HD3000, but have not verified this.

  You should always beware of what new cpu you use as not all of them have an integrated graphics card.

  EDIT: Did a double check and found this on the site of Open GL (this would be for the continued support and would not affect the Intel HD graphics which is able to use OpenGL 4.0) -.

  "Intel does not provide an implementation of OpenGL correct and up to date for their Integrated GPU. There is nothing that can be done about it. ATI and NVIDIA provide good support for their Integrated GPU. »

• GlRotatef OpenGL function may not work in the ForeignWindow control

  Hello

  I wrote a demo to display a rectangle rotated in control of foreignWindow, the rectangle has shown, but can not turn:

  So, is there something I'm doing wrong with the code, or is it just a limitation of foreignWindow?

  The following code is part of my demo:

  Sub MyForeignWindow::render()
  {
  glClear(GL_COLOR_BUFFER_BIT |) GL_DEPTH_BUFFER_BIT);

  glEnableClientState (GL_VERTEX_ARRAY);
  glVertexPointer (2, GL_FLOAT, 0, this-> top);

  glEnableClientState (GL_COLOR_ARRAY);
  glColorPointer (4, GL_FLOAT, 0, this-> colors);

  glRotatef (0.5f, 0.0F, 0.0F, 1.0F);

  glDrawArrays (GL_TRIANGLE_STRIP, 0, 4);

  glDisableClientState (GL_VERTEX_ARRAY);
  glDisableClientState (GL_COLOR_ARRAY);

  This-> swap();
  }

  try changing the angle of 45 degrees for example. ... it does not turn? or is there an opengl error?

  You can get this error with eglGetError()

  Do you use a glpushmatrix in another function of rendering (opengl is a statemachine!)

• OpenGL create fails texture

  Hi, I wrote an application to display pictures with OpenGL ES 2.0 and Android APIs. But trying to create a texture of my loaded Bitmap, the GLSurfaceView shows just a black rectangle. The rectangle has the same proportions as my loaded image, so I guess that, only the color of image data are missing. Application of a shader with the texture, I can change the color (for example in a white rectangle). Therefore: - GLSufaceView - works. -Shader - work - open InputStream and get a picture - work the only thing in the middle is the texture to create call. I follow the example android, see here: http://developer.android.com/resources/samples/ApiDemos/src/com/example/android/apis/graphics/GLES20... Can someone help me? Did anyone have experience with OpenGL ES 2.0 and upload texture on Playbook? Is there a good way to debug the application? Currently I use AlertDialog for information. How can I get the LogCat messages? Thanks - Robert

  The texture should be square and the width and height should be something of a power of 2 (= 1024). Sorry for the confusion.

• Button menu at the top of the surface of the OpenGL

  I'm working on a project that uses OpenGL ES 1.1. Now I want to place buttons of Menus &, resembling a little to a HUD.

  What is the best way to do something like that?
  I understand that there is probably a lot of games using this because it seems natural quiet.

  Is it possible to use Qt on top of the surface of OpenGL?

  Is there some demo Apps out there that do exactly what?

  I have searched for it, but couldn't really find anything that addresses this issue.

  Clean user interface-> you want a button.

  Draw a rectangular shape with rounded corners, put a text in it.

  Next to main event processing listen touch event. The touch event check if a user has touched within the limits of your button, change Yes wait your button Pressed (argument) and reacts to this press event.

  Yes, it's a lot of work. I did once to a single application and it does not require a lot of coding.

  On a plus side once you develop this 'infrastructure' of your own interface user then you can reuse it in all your applications.

  Hi, we develop software on Ubuntu, and of course, we use VMware for that, for all the usual reasons large. We use an API that supports Ubuntu 12.04, 14.04 and now 16.04. We decided to go to 16.04, like its new and shiny. But it seems to be serious problems with OpenGL in 16.04, breaking OpenGL based apps. Or else, they work and produced a terrible performance.

  A colleague has glmark2 on a physical machine from Ubuntu16.04, and it has not crashed. BUT there does appear to be a pretty awful performance, with a score of 200, compared to 2000 + on Ubuntu VMWare 14.04. It was also to launch a large NUMBER of errors.

  It looks like VMWare can do something to remedy this situation?

  HM, this might be a limitation of our stack of graphics, but we have the graphic team to take a look.
