opengl2.0 software introduction
Fully written Open Graphics Library, which defines a cross-programming language and cross-platform programming interface (Application programming interface), which is used to generate two-dimensional and three-dimensional images. This interface consists of nearly 350 different function calls used to draw complex 3D scenes from simple primitives. And another programming interface system is only used by Microsoft Direct3D on Windows. OpenGL is commonly used in CAD, virtual reality, scientific visualization programs, and video game development.
opengl2.0 installation tutorial
1. If it is VS2008, copy glut.h to x:Program FilesMicrosoftVisual Studio 9.0VCincludeGL folder, if there is no GL folder, you can create a new one yourself. (x is the disk symbol where you installed VS. If you installed VC++, there is a gl file in it. Visual Studio 2008 requires you to create a new one yourself)
2. If it is vc6.0, then you need to find the opengl library, put the header file into the include folder in the directory where the VC is located (VC98/include/GL), and put *.lib into the lib folder (VC98/Lib), put the dll into c:/windows/system32, and just add the header file to include during development.
3. Place the decompressed glut.dll and glut32.dll into the system32 folder under the operating system directory. (Typical location: C:WindowsSystem32)
4. Put the decompressed glut.lib and glut32.lib into the folder where the static function library is located (that is, under the lib folder side by side with include).
opengl2.0 FAQ
How to set up opengl rendering gpu
1. Click "Rendering Settings" (F10) on the menu bar, lock the aspect ratio of the picture frame, and then select "3200*2250" as the "Width and Height".
2. Then, Vray-global switch - turns off global illumination, the final image will not be rendered without checking.
3. Then, enable anti-aliasing filtering for image sampler-type adaptive deterministic Monte Carlo, adaptive subdivision, and color map-type linear multiplication.
4. Next, indirect lighting-enable indirect lighting-select "Light Map" in the first bounce-select "Light Cache" in the second bounce.
5. Next, for the luminescence map - select Low Hemisphere 80 in the current preset - Interpolation Sample 50.
6. Light cache, subdivided by 1800.
7. DMC sampler settings, currently set to high, hemispheric subdivision 80, interpolation sampling 50.
8. Rendering area division settings and area order can be selected from top to bottom, left to right or other methods.
9. Finally save the preset and the setting is completed.
What should I do if the opengl version is too low?
Reason 1. Your computer does not have a graphics card
This problem is temporarily unsolvable without changing the computer hardware. We can only wait until our simulator supports integrated graphics cards.
Reason 2. The driver for the computer graphics card does not exist or is too old.
Download the driver, detect and install the graphics card driver
Run the driver and click "One-click physical check" to install or update your graphics card driver
(1) If the universal driver is installed, update the graphics card driver, then restart the computer and install it again
(2) If it is a series of graphics cards, you need to replace the graphics card all the time.
If after updating the graphics card driver, green screen, blurry screen and other abnormal display phenomena appear on the computer screen, you can try to roll back the graphics card driver.
1) Run the driver
2) Select driver → graphics card (if you have dual graphics cards, choose independent graphics) → select the old version driver to roll back the driver
After setting these, our software can be upgraded directly.
Reason 3. Your computer graphics card does not support
Solution: This problem can only be solved by replacing the graphics card
