hobbies

A place to collect and share all my hobby projects.

build - where the build temporaries are collected
install - where the build outputs are collected
projects - The set of projects
- basal - a core library of utility objects and interfaces.
- linalg - the core matrix oriented math library
- linalg-algo - high level math algorithms
- linalg-utils - a compatibility library for using OpenCV.
- geometry - the 2D/3D geometry objects
- noise - A 2D image noise generator, useful in textures or other means
- fourcc - a small image library
- neuralnet - a simple NN w/ hidden layers
- raytrace - a fairly simple raytracer
- htm - the start of a hierarchical temporal memory system.
- units_of_measure - mechanism to create types which represent Units of Measure.
- xmmt - SSE2/AVX512 inline assembly vector and matrix headers.

Check the README in each folder for it's own progress and issues.

General Design Principles

All math oriented objects must implement
- operators == != += -= *= /= + - * / ! in the class or operators namespace as friends
Must use basal::equals for best float checks
Consistent use of either read-only members or methods.
const correctness.
Must support basal::printable
Must support friend operator<<
Use explicit Constructors to prevent unanticipated auto-magic
Use if constexpr for debugging.
Always install your header files as read-only!
Always create your generated source code as read-only!
Only locally install binaries (install/). These shouldn't pollute your system.

Developing

You can open either the hobbies.code-workspace or the folder itself. Currently VSCode is not intelligent about running configure in order.

Building

Currently you can run the ./separate_builds.sh -rm -s to individually config, build, and install each package. All the artifacts will end up in a new install/ folder.

Conan

Hobbies can be build using Conan (http://conan.io). In Windows for Linux, and older versions of Linux you can use the wsl_conanfile.txt to setup a build environment and then call the ./separate_build.sh -c to use Conan to communicate between projects.

conan install wsl_conanfile.txt
source ./activate.sh
./separate_builds.sh -rm -c
source ./deactivate.sh

Running

While in the hobbies' root, you can run things by pre-pending the LD (DYLD) path.

# Running the NCurses Raytracing Console on Mac
DYLD_LIBRARY_PATH=install/lib:build/raytrace ./build/raytrace/demo_curses -m libworld_example.dylib

Testing Folder

I've added an explicit folder to run tests. You can run them using the testing wrapper script (it will temporarily modify your PATH and *LD_LIBRARY_PATH).

cd testing
./testing.sh demo_curses -m ../build/raytrace/libworld_example.dylib

VS Code order of precedence processing

VSCode will take settings in the order of:

.code-workspace
.vscode/settings.json
project/**/.vscode/settings.json
