Re: [osg-users] Compiling vertext shader fails on Intel

Hi Chris, I managed to work around the issue by falling back to a slower rendering system. Also it turns out the laptop has a switchable graphics subsystem to nVidia ( which works perfectly) or Intel, so there are two workarounds. I'll check out that validator. Thanks Andrew

Re: [osg-users] Compiling vertext shader fails on Intel

I think compiling the shader is deferred until it's actually needed. The fact that it doesn't list WHAT extension it needs suggests to me that the driver is just broken and there may not be anything you can do. You could try a validator and see if it flags anything wrong with your GLSL code:

Re: [osg-users] Compiling vertext shader fails on Intel

Sadly although the driver is old, apparently it can't be updated to a newer version on this DELL laptop. Also, I am struggling a bit to detect/recover from the failure of "glLinkProgram". It appears this is delayed until the "first render" using the shader. -- Read this topic

That driver release dates from at least 2015 from what I can see. Isn't there anything newer available, before you go stressing about it? On Fri, Dec 14, 2018 at 8:29 PM Andrew Cunningham wrote: > Hi, > I am using a vertex shader to do some hardware instancing and on Intel > graphics drivers I

Are you talking about the rendering aspect or the cloth dynamics simulation aspect? On Fri, Dec 14, 2018 at 3:35 PM Werner Modenbach wrote: > Hi all, > > first of all I apologize for an off topic question. > I spent weeks already in the Internet for finding a solution for a > problem - without

[osg-users] Compiling vertext shader fails on Intel

Hi, I am using a vertex shader to do some hardware instancing and on Intel graphics drivers I am getting the error ( after I set OSG_NOTIFY_LEVEL=DEBUG). Everything works great on nVidia. OpenGL Information: OpenGL Version: 4.2.0 - Build 10.18.10.3574 Vendor: Intel Renderer: Intel(R) HD Graphics

[osg-users] Off topic question and request for ideas

Hi all, first of all I apologize for an off topic question. I spent weeks already in the Internet for finding a solution for a problem - without success. And I know there are a lot of experienced people here in the list. I'm doing high quality simulations of textiles from machine data. So I have
