RAYGIZMO

raygizmo was designed as an auxiliar module for raylib to create simple interactive gizmo gadget to perform basic object transformation (rotation and translation).

NOTE: raygizmo is a single-file header-only library (despite its internal dependency on raylib), so, functions definition AND implementation reside in the same file raygizmo.h, when including raygizmo.h in a module, RAYGIZMO_IMPLEMENTATION must be previously defined to include the implementation part of raygizmo.h BUT only in one compilation unit, other modules could also include raygizmo.h but RAYGIZMO_IMPLEMENTATION must not be defined again.

NOTE: Current raygizmo implementation is intended to work with raylib-5.0 and PLATFORM_DESKTOP

Example

In a simplest case gizmo can be used like this:

// Draw the model here:
BeginMode3D(camera);
    DrawModel(model, ...);
EndMode3D();

// Immediately update and draw gizmo
Vector3 position = {
    model.transform.m12, model.transform.m13, model.transform.m14};
Matrix transform = UpdateGizmo(camera, position);

// Apply gizmo-produced transformation to the model
model.transform = MatrixMultiply(model.transform, transform);

Interactive example could be built and run like this:

cd examples \
&& gcc -o ./gizmo ./gizmo.c -lraylib -lm -lpthread -ldl \
&& ./gizmo
