|
@ref DebugTools library provides various helper classes to help you with |
|
prototyping and debugging applications without the need to write too much |
|
common code. They probably have no usage in production code, but can be useful |
|
in development. See documentation of @ref DebugTools namespace for more |
|
information about building and usage with CMake. |

@section debug-tools-renderers Debug renderers |
|
|
|
Debug renderers provide a way to visualize objects and object features in |
|
@ref scenegraph "scene graph" without the need to mess around with meshes and |
|
shaders. They are implemented as object features, so you can attach any number |
|
of them to any object. |
|
|
|
Basic usage involves instancing @ref DebugTools::ResourceManager and keeping it |
|
for the whole lifetime of debug renderers. Next you need some |
|
@ref SceneGraph::DrawableGroup instance. You can use the same group as for the |
|
rest of your scene, but preferrably use dedicated one for debug renderers, so |
|
you can easily enable or disable debug rendering. |
|
|
|
Next step is to create configuration for your debug renderers and create |
|
particular debug renderer. The configuration is managed using the resource |
|
manager - you create configuration instance, add it to the manager and then |
|
reference it using particular resource key. This way you can easily share the |
|
same options with more renderers. If no options are specified or resource with |
|
given key doesn't exist, default fallback is used. |
|
|
|
Example usage: visualizing object position, rotation and scaling using |
|
@link DebugTools::ObjectRenderer @endlink: |
|
@code |
|
// Global instance of debug resource manager, drawable group for the renderers |
|
DebugTools::ResourceManager manager; |
|
SceneGraph::DrawableGroup3D debugDrawables; |
|
|
|
// Create renderer options which will be referenced later by "my" resource key |
|
DebugTools::ResourceManager::instance()->set("my", |
|
DebugTools::ObjectRendererOptions().setSize(0.3f)); |
|
|
|
// Create debug renderer for given object, use "my" options for it. The |
|
// renderer is automatically added to the object features and also to |
|
// specified drawable group. |
|
Object3D* object; |
|
new DebugTools::ObjectRenderer2D(*object, "my", debugDrawables); |
|
@endcode |
|
|
|
See @ref DebugTools::ObjectRenderer and @ref DebugTools::ShapeRenderer for more |
|
information. |
