# OpenGL [VC++8] SDL and OpenGL

## Recommended Posts

Okay, I've used SDL and OpenGL for about 3 years now. However, I never really figured out how to correctly set up OpenGL with SDL in Visual C++ 2005 express. I mean I got it to work with some really hacky methods that I can't figure out. It's been about 2 months since I took a break from C++ to mess around with other languages. I just got a physics project and I can't for the life of me figure out how to set up OpenGL with SDL correctly. Okay, I just reinstalled VC++ and deleted all my old SDL version 1.2.10 . I still have the platform SDK in my programs folder though. Is there any walk throughs to setting it up correctly and compiling a very simple
int main (int argc, char* argv[])
{
return 0;
}


application. If anyone could show a tutorial or just quickly explain exactly what to install and do, I would be greatly appreciated. One thing I noticed: http://www.libsdl.org/download-1.2.php There's no VC++8 libraries. I think when I made my old games one of my on-line friends sent me the compiled libraries for VC++8. I need VC++8 libraries right? Or am I just mistaken. At the moment I'm confused so anyone's help would be greatly appreciated. I just don't want to have to end up programming this physics project in VB.NET or something... :( Time is of the essence. So if you think helping me on IRC is faster then: /server irc.freenode.net /join #gpwiki

Well, it's pretty simple really. First, use the VC6 file from the sdl website.

And setting up an opengl project is just as easy as a normal SDL project, just set the SDL_OPENGL flag and include SDL_opengl.h

Then don't forget to link with "SDL.lib SDLmain.lib OpenGL32.Lib"

This is just a simple initializations example.

#include "SDL.h"
#include "SDL_opengl.h"

int main( int arc, char* args[] )
{
SDL_Surface* pSurfScreen = 0;

if( SDL_Init( SDL_INIT_VIDEO|SDL_INIT_VIDEO )

I got it to work about 5 hours after I posted this. For some reason I actually didn't have an entry point. The word main was gone from my project settings. That was really odd since I've never even seen that property, nor changed it.

Thanks anyway. :)

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?

• Hello all,

On my Windows 7 x64 machine I wrote the code below on VS 2017 and ran it.
#include <glad/glad.h>  #include <GLFW/glfw3.h> #include <std_lib_facilities_4.h> using namespace std; void framebuffer_size_callback(GLFWwindow* window , int width, int height) {     glViewport(0, 0, width, height); } //****************************** void processInput(GLFWwindow* window) {     if (glfwGetKey(window, GLFW_KEY_ESCAPE) == GLFW_PRESS)         glfwSetWindowShouldClose(window, true); } //********************************* int main() {     glfwInit();     glfwWindowHint(GLFW_CONTEXT_VERSION_MAJOR, 3);     glfwWindowHint(GLFW_CONTEXT_VERSION_MINOR, 3);     glfwWindowHint(GLFW_OPENGL_PROFILE, GLFW_OPENGL_CORE_PROFILE);     //glfwWindowHint(GLFW_OPENGL_FORWARD_COMPAT, GL_TRUE);     GLFWwindow* window = glfwCreateWindow(800, 600, "LearnOpenGL", nullptr, nullptr);     if (window == nullptr)     {         cout << "Failed to create GLFW window" << endl;         glfwTerminate();         return -1;     }     glfwMakeContextCurrent(window);     if (!gladLoadGLLoader((GLADloadproc)glfwGetProcAddress))     {         cout << "Failed to initialize GLAD" << endl;         return -1;     }     glViewport(0, 0, 600, 480);     glfwSetFramebufferSizeCallback(window, framebuffer_size_callback);     glClearColor(0.2f, 0.3f, 0.3f, 1.0f);     glClear(GL_COLOR_BUFFER_BIT);     while (!glfwWindowShouldClose(window))     {         processInput(window);         glfwSwapBuffers(window);         glfwPollEvents();     }     glfwTerminate();     return 0; }
The result should be a fixed dark green-blueish color as the end of here. But the color of my window turns from black to green-blueish repeatedly in high speed! I thought it might be a problem with my Graphics card driver but I've updated it and it's: NVIDIA GeForce GTX 750 Ti.
What is the problem and how to solve it please?
