# VEGA Engine
A simple 3D game engine written in C++ using OpenGL.
# Examples
## Creating a window.
```c++
#include
int main(int argc, const char* argv[]) {
vega::VEGAWindow window(1200, 600, "VEGA Window");
while (!window.shouldClose()) {
window.pollEvents();
window.clear();
window.checkErrors();
window.swapBuffers();
}
window.destroy();
return 0;
}
```
## Rendering a model.
```c++
#include
int main(int argc, const char* argv[]) {
vega::VEGAWindow window(1200, 600, "VEGA Window");
vega::VEGAShader shader(
vega::VEGAReadFile("shaders/default.vert"),
vega::VEGAReadFile("shaders/default.frag")
);
vega::VEGACamera camera(&window, 45.0f, 0.1f, 1000.0f);
vega::VEGAModel model("res/models/crow/scene.gltf");
shader.use();
glUniform4fv(shader.getUniformLocation("lightColor"), 1, (float*) glm::value_ptr(glm::vec4(1.0f, 1.0f, 1.0f, 1.0f)));
glUniform3fv(shader.getUniformLocation("lightPosition"), 1, (float*) glm::value_ptr(glm::vec3(0.5f, 0.5f, 0.5f)));
glUniform1f(shader.getUniformLocation("ambient"), 0.2f);
shader.unuse();
while (!window.shouldClose()) {
window.pollEvents();
camera.processInputs();
window.clear();
model.render(&shader, &camera);
window.checkErrors();
window.swapBuffers();
}
model.destroy();
shader.destroy();
window.destroy();
return 0;
}
```
