DirectX Math Overview

Introduction

This document provides a quick overview of the Math section within DirectX. Understanding this section is crucial for developers working with DirectX 12, particularly when dealing with linear algebra, vector operations, and coordinate transformations.

Core Concepts

DirectX focuses on a specific set of mathematical primitives for rendering graphics, especially when dealing with vectors and matrices. The Math section defines the fundamental operations.

Key Operations

Here are a few core operations:

• Vector Operations: Representing and manipulating points (x, y, z coordinates).
• Matrix Operations: Transforming and manipulating matrices. These are fundamental for transformations and calculations.

• Linear Algebra: The foundation of many graphics calculations, including rotations, scaling, and projections.

• Coordinate Transformations: Rotating, scaling, translating, and projecting 3D points.

Example: Projection

Consider a simple 3D scene. We want to project a point from the scene to the 2D screen. This involves a projection matrix that maps the 3D point to a 2D point.

The projection matrix represents the transformation.
