C++ (Cpp) setLightPos Examples

Example #1

File: Window.cpp Project: johans/lab4

void Window::moveLight(SDLKey sdlKey)
{
    Vec4 p = getLightPos();
    switch (sdlKey) {
        case SDLK_LEFT:
            p[0] -= 0.1f;
            break;
        case SDLK_RIGHT:
            p[0] += 0.1f;
            break;
        case SDLK_UP:
            p[1] += 0.1f;
            break;
        case SDLK_DOWN:
            p[1] -= 0.1f;
            break;
        case SDLK_PAGEUP:
            p[2] += 0.1f;
            break;
        case SDLK_PAGEDOWN:
            p[2] -= 0.1f;
            break;
    }
    setLightPos(p);
    glLightfv(GL_LIGHT0, GL_POSITION, p.ptr());
    cout << "GL_LIGHT0 position: " << p << endl;
