Macro Definition Documentation

#define HLSLPP_FEATURE_TRANSFORM
#define HLSLPP_MODULE_DECLARATION

Math helpers built on top of hlsl++ types.

This module provides common math utilities and matrix/quaternion helpers used across the engine, including view/projection matrix builders, a quaternion-to-Euler conversion, tolerant comparisons, and simple random number generation utilities.
