move-vectormath

move-vectormath is the Move math library for vectors, matrices, quaternions, and scalar math helpers.

It can be consumed either:

• as a Move package (move/math)
• as a plain CMake dependency via add_subdirectory, FetchContent, CPM, or similar workflows

Layout

• Public umbrella header: packages/move/math/include/move/vectormath.hpp
• Core public headers: packages/move/math/include/move/math
• Tests: packages/move/math/tests
• Math conventions: CONVENTIONS.md

Public Surface

The umbrella header exports:

• vec2, vec3, vec4
• quat
• mat3x3, mat4x4
• common math helpers from move::math

Backend behavior is intentionally mixed:

• vec2 is currently scalar-only.
• Floating-point vec3, vec4, matrices, and quaternions use the RTM-backed path where applicable.
• Integral vector types use the scalar path.

Usage

#include <move/vectormath.hpp>

using namespace move::math;

float3 a(1.0f, 2.0f, 3.0f);
float3 b(4.0f, 5.0f, 6.0f);
float3 sum = a + b;

quatf rotation = quatf::rotation_y(deg2rad(90.0f));
float3 rotated = float3::forward() * rotation;

See CONVENTIONS.md for coordinate-system, transform, and rotation semantics.

Integration

Move Package

In a Move project, depend on move/math and include the umbrella header:

#include <move/vectormath.hpp>

Typical Move CLI workflows from the repository root are:

move-cli build move/math
move-cli test move/math

CMake

The top-level CMake project exports an interface target named move-vectormath with aliases:

• move::vectormath
• move::math
• move-math

The recommended link target for consumers is move::vectormath.

add_subdirectory

add_subdirectory(path/to/move-vectormath)

target_link_libraries(your_target
  PRIVATE
    move::vectormath
)

FetchContent

include(FetchContent)

FetchContent_Declare(
  move_vectormath
  GIT_REPOSITORY https://github.com/move-engine/move-vectormath.git
  GIT_TAG main
)

FetchContent_MakeAvailable(move_vectormath)

target_link_libraries(your_target
  PRIVATE
    move::vectormath
)

CPM

include(cmake/CPM.cmake)

CPMAddPackage(
  NAME move-vectormath
  GITHUB_REPOSITORY move-engine/move-vectormath
  GIT_TAG main
)

target_link_libraries(your_target
  PRIVATE
    move::vectormath
)

After linking, include the public umbrella header:

#include <move/vectormath.hpp>

or the specific headers under move/math if you prefer.

Testing

From the repository root:

move-cli test

The test sources live under packages/move/math/tests.
