C++ (Cpp) load_identity Examples

Example #1

File: window.cpp Project: bhelyer/Yume

	window::window(int w, int h, int cmdShow) : width(w), height(h), nCmdShow(cmdShow), a(255) {
		LARGE_INTEGER lpFrequency;
		QueryPerformanceFrequency(&lpFrequency);
		pcFrequency = static_cast<double>(lpFrequency.QuadPart);
		min_frame_length = 0.0;
		frame_rate = 0.0;
		load_identity();
		yume_register_window();
		hwnd = CreateWindowEx(0, L"yumewindow", L"хдв Software Renderer", WS_OVERLAPPEDWINDOW, CW_USEDEFAULT, CW_USEDEFAULT, width, height, nullptr, nullptr, GetModuleHandle(nullptr), this);
		if (hwnd == nullptr) {
			panic(L"Couldn't create window.", nullptr);
		}
	}

Example #2

File: simulation.c Project: Jem777/orbits3d

void draw_objects(simulation_t *simulation, buffer_t *buffer, shader_t *shader, GLfloat camera[16]) {
    GLfloat modelview[16];
    for (unsigned int i = 0; i < simulation->count; i++) {
        particle_t particle = simulation->src_buf[i];
        vec3f p = particle.position;
        load_identity(modelview);
        translate(modelview, p.x, p.y, p.z);
        scale(modelview, particle.radius, particle.radius, particle.radius);
        multiply_matrix(modelview, camera, modelview);
        set_matrix(shader, MODELVIEW_MATRIX, modelview);
        glColor3f(particle.r, particle.g, particle.b);
        draw_vbo(buffer);
