🎨 graphics - Grafik ve Rendering

🚀 Hızlı Başlangıç

içe_aktar graphics

// Window oluştur
değişken pencere = graphics.window_create("BERK Graphics", 800, 600)

// OpenGL context
değişken gl = graphics.gl_context_create(pencere)
graphics.gl_make_current(gl)

// Shader program
değişken vertex_shader = graphics.shader_compile(VERTEX_SHADER, vertex_code)
değişken fragment_shader = graphics.shader_compile(FRAGMENT_SHADER, fragment_code)
değişken program = graphics.program_link(vertex_shader, fragment_shader)

// Vertex data
değişken vertices = [
    -0.5, -0.5, 0.0,  // sol alt
     0.5, -0.5, 0.0,  // sağ alt
     0.0,  0.5, 0.0   // üst
]

değişken vbo = graphics.buffer_create()
graphics.buffer_data(vbo, vertices)

// Render loop
döngü yap
    graphics.clear(0.2, 0.3, 0.3, 1.0)
    
    graphics.program_use(program)
    graphics.draw_arrays(TRIANGLES, 0, 3)
    
    graphics.window_swap_buffers(pencere)
    graphics.poll_events()
    
    eğer graphics.window_should_close(pencere) ise yap
        kır

📚 Özellikler

• OpenGL 3.3+: Modern OpenGL API
• Vulkan: Low-level graphics API (experimental)
• Shaders: GLSL vertex/fragment/geometry/compute shaders
• Textures: 2D/3D textures, mipmaps, filtering
• Framebuffers: Render-to-texture, post-processing
• 3D Math: Matrices, vectors, quaternions

     0.5,  0.5, -0.5,  1.0, 1.0,
    // ... (diğer yüzler)
]

// Load texture
değişken texture = graphics.texture_create()
değişken img = image.load("crate.png")
graphics.texture_data(texture, img.genişlik, img.yükseklik, img.veri)
graphics.texture_set_filter(texture, LINEAR, LINEAR_MIPMAP_LINEAR)

// Camera
değişken kamera = yap
    pozisyon: [0.0, 0.0, 3.0],
    hedef: [0.0, 0.0, 0.0],
    yukarı: [0.0, 1.0, 0.0]

// Transformation matrices

// Render

// Framebuffer oluştur

// Post-processing shader (grayscale)

// Render loop
döngü yap
    // 1. Render sahneyi framebuffer'a
    graphics.framebuffer_bind(fbo)
