### Vector3D integral multiplication example

Source: https://srl.reye.me/structSRL_1_1Math_1_1Types_1_1Vector3D_a3db3c71e88547d1c843b3977b58401be.html

Shows how to use the integral-type operator*= on a Vector3D. The example creates a vector (1, 2, 3) and multiplies it by 2, resulting in (2, 4, 6) with optimized integral multiplication.

```cpp
Vector3D v(1, 2, 3);
v *= 2; // Results in v = (2, 4, 6) with optimized integral multiplication
```

### Vector2D::Length() example with standard and Turbo precision

Source: https://srl.reye.me/structSRL_1_1Math_1_1Types_1_1Vector2D_a2b60208c3c93bc225339a8007c3bb12e.html

Constructs a Vector2D with coordinates (3, 4) and calls Length() with default precision to get the exact length 5, then calls Length<Precision::Turbo>() to get a faster approximate length. The Turbo variant uses a fast approximation with alpha-beta coefficients instead of an exact square root.

```cpp
Vector2D v(3, 4);
Fxp length = v.Length(); // Returns 5 (standard precision)
Fxp fastLength = v.Length<Precision::Turbo>(); // Returns approximate length (faster)
```

### SetMask() example: enable V-Blank In and disable all interrupts

Source: https://srl.reye.me/classSRL_1_1Interrupt_a207855a109067e30a9c37b399854da23.html

Use to replace the entire SCU interrupt mask. Set bits disable the corresponding interrupt source. The example enables only V-Blank In and then disables all interrupts.

```cpp
// Enable only V-Blank In
Interrupt::SetMask(Interrupt::Mask::VBlankIn);
// Disable all interrupts
Interrupt::SetMask(Interrupt::Mask::All);
```

--------------------------------

### Fxp usage example: conversion and arithmetic

Source: https://srl.reye.me/classSRL_1_1Math_1_1Types_1_1Fxp.html

Shows compile-time and runtime conversion, arithmetic operations, and conversion back to an integer type. Compile-time conversion is preferred; runtime conversion with Fxp::Convert includes range checking and a performance warning. The example uses constexpr for compile-time evaluation.

```cpp
// Compile-time conversion (preferred)
constexpr Fxp a = 5; // 5 (0x00050000)
constexpr Fxp b = 2.5; // 2.5 (0x00028000)
// Runtime conversion
Fxp c = Fxp::Convert(someInt); // With range checking
Fxp d = Fxp::Convert(someFloat); // With performance warning
// Arithmetic operations
Fxp result = a * b; // 12.5 (0x000C8000)
int16_t i = result.As<int16_t>(); // 12
```

--------------------------------

### CreateScale() example: uniform scale by 2

Source: https://srl.reye.me/structSRL_1_1Math_1_1Types_1_1Matrix33_a7fafb224b4ac5f51343d66e8c2d2296b.html

Creates a non-uniform scale matrix using CreateScale and applies it to a vector. The example shows uniform scaling by 2, producing (2, 2, 2) when multiplied by (1, 1, 1). Unlike Scale(), this method returns a fresh matrix that only represents scaling without affecting rotation.

```cpp
Matrix33 scaleMatrix = Matrix33::CreateScale(Vector3D(2, 2, 2)); // Uniform scale by 2
Vector3D scaled = scaleMatrix * Vector3D(1, 1, 1); // Results in (2, 2, 2)
```

Source: https://srl.reye.me/classSRL_1_1Tickstamp_aeaf91c6bc27d5b8ff95e063e89f407c7.html

Shows how to use ToMilliseconds() to get elapsed time in milliseconds. The example checks if the elapsed time exceeds 16 ms (indicating a slow frame). Note the 32767 ms maximum range; use ToSeconds() for longer durations.

Shows how to use ToClock() to get a ClockTime from a Tickstamp difference and format it into a string. The example uses sprintf with the ClockTime components. Note that ClockTime is immutable and intended for display only; use ToSeconds()/ToMilliseconds() for precise timing.

```cpp
Tickstamp elapsed = end - start;
ClockTime ct = elapsed.ToClock();
// Display as "02:15:30.500"
sprintf(buf, "%02u:%02u:%02u.%03u",
ct.Hours(), ct.Minutes(), ct.Seconds(), ct.Milliseconds());
```

Initializes basic environment, setting the screen back color and optional TV resolution. It is a static inline method in the SRL Core namespace.

```APIDOC
## SRL::Core::Initialize()

### Description
Initializes basic environment for the SGL wrapper, setting the screen back color and TV resolution.

### Method Signature
void SRL::Core::Initialize(const Types::HighColor &_backColor_, const TV::Resolutions _resolution_ = TV::Resolutions::Normal320x240)

### Parameters
- **backColor** (Types::HighColor) - Required - Color of the screen.

--------------------------------

### Measure elapsed time with SRL::Timer::Capture()

Source: https://srl.reye.me/classSRL_1_1Timer_ab73ab36d21c237a8407658de4f760754.html

Call Capture() at the start and end of an operation to measure elapsed time. The returned Tickstamp values can be subtracted to get an elapsed Tickstamp, which can be converted to seconds using ToSeconds(). Capture() reads hardware registers on each call and uses a memory barrier, so prefer CurrentTickstamp() for in-frame timing that doesn't require a fresh hardware read.

```cpp
Tickstamp start = Timer::Capture();
// ... perform operation ...
Tickstamp end = Timer::Capture();
Tickstamp elapsed = end - start;
Fxp seconds = elapsed.ToSeconds();
```
