# OpenGL OpenGL driver issue

## Recommended Posts

I have been working on an engine. In my engine's log, I always print the OpenGL driver, version, and supported extentions. I just checked the log after a test today, and found that my computer was suddenly using the Microsoft Generic GDI driver instead of the normal GeForce driver. I have a GeForce FX 5500, BTW. There are only 3 extenntions listed for it as well! I have restarted, recompiled, reinstalled drivers, etc. Even my bought games are reporting the same thing. A few of them will not even start now! I have googled and found that many people are experiencing the same thing. I have not found a cause, or solution for this problem though. I have been trying to solve this own, but I am honestly clueless on this one. This "error" just popped out of nowhere!!! Other than updating DirectX drivers, I have not installed ANYTHING! The "normal" OpenGL drivers were working fine one moment, then the next they wree not!!!!!!!! Any help or advice will be appreciated.

try first using the the default generaic 640x480x16 drivers (not the vnidia ones) reboot the computer, and then install the nvidia ones (not by running the nvidia setup.exe, but manually)

I switched the primary monitor, and tried to start Warhammer 40k and it worked fine. I tried my OpenGL app with both monitors set to primary, but I still get the same problem. Why is one monitor working and the other one is not! They are both connected to the same card! I have been googling for an answer to this. I have uninstalled all drivers and reinstalled them fresh but still got the same problem.

Warhammer works because I can explicitly tell it what device to use. It has a list that says: Default, Device 0: NVIDIA Dualview, and Device 1: NVIDIA GeForce FX 5500. I chose Device 1 and it worked. I guess that Default is set to Device 0.

Anyone have any clue as to why the two devices are using seperate drivers even though they are on the same card?

oh so youve got two monitors, thats something else (as i dont have two monitors ive never done it) but from what i read before u have to much araound a bit to get it up and running,
read the pdf's from nvidia (perhaps they explain what to do), also search the forums at www.opengl.org

• Both functions are available since 3.0, and I'm currently using glMapBuffer(), which works fine.
But, I was wondering if anyone has experienced advantage in using glMapBufferRange(), which allows to specify the range of the mapped buffer. Could this be only a safety measure or does it improve performance?
Note: I'm not asking about glBufferSubData()/glBufferData. Those two are irrelevant in this case.

Before using void glBindImageTexture(    GLuint unit, GLuint texture, GLint level, GLboolean layered, GLint layer, GLenum access, GLenum format), does need to make sure that texture is completeness.

hi guys,
are there any books, link online or any other resources that discusses on how to build special effects such as magic, lightning, etc. in OpenGL? i mean, yeah most of them are using particles but im looking for resources specifically on how to manipulate the particles to look like an effect that can be use for games,. i did fire particle before, and I want to learn how to do the other 'magic' as well.
Like are there one book or link(cant find in google) that atleast featured how to make different particle effects in OpenGL (or DirectX)? If there is no one stop shop for it, maybe ill just look for some tips on how to make a particle engine that is flexible enough to enable me to design different effects/magic
let me know if you guys have recommendations.

How do we rotate the camera around x axis 360 degrees, without having the strange effect as in my video below?
Mine behaves exactly the same way spherical coordinates would, I'm using euler angles.
Tried googling, but couldn't find a proper answer, guessing I don't know what exactly to google for, googled 'rotate 360 around x axis', got no proper answers.

The video shows the difference between blender and my rotation:

I've had a Google around for this but haven't yet found some solid advice. There is a lot of "it depends", but I'm not sure on what.
My question is what's a good rule of thumb to follow when it comes to creating/using VBOs & VAOs? As in, when should I use multiple or when should I not? My understanding so far is that if I need a new VBO, then I need a new VAO. So when it comes to rendering multiple objects I can either:
* make lots of VAO/VBO pairs and flip through them to render different objects, or
* make one big VBO and jump around its memory to render different objects.
I also understand that if I need to render objects with different vertex attributes, then a new VAO is necessary in this case.
If that "it depends" really is quite variable, what's best for a beginner with OpenGL, assuming that better approaches can be learnt later with better understanding?
