Inherit from this class to simplify implementing a debug renderer, start with this implementation:
class MyDebugRenderer : public JPH::DebugRendererSimple
{
public:
virtual void DrawLine(JPH::RVec3Arg inFrom, JPH::RVec3Arg inTo, JPH::ColorArg inColor) override
{
// Implement
}
virtual void DrawTriangle(JPH::RVec3Arg inV1, JPH::RVec3Arg inV2, JPH::RVec3Arg inV3, JPH::ColorArg inColor, ECastShadow inCastShadow) override
{
// Implement
}
virtual void DrawText3D(JPH::RVec3Arg inPosition, const string_view &inString, JPH::ColorArg inColor, float inHeight) override
{
// Implement
}
};
Note that this class is meant to be a quick start for implementing a debug renderer, it is not the most efficient way to implement a debug renderer.

Draw some geometry
| inModelMatrix | is the matrix that transforms the geometry to world space. |
| inWorldSpaceBounds | is the bounding box of the geometry after transforming it into world space. |
| inLODScaleSq | is the squared scale of the model matrix, it is multiplied with the LOD distances in inGeometry to calculate the real LOD distance (so a number > 1 will force a higher LOD). |
| inModelColor | is the color with which to multiply the vertex colors in inGeometry. |
| inGeometry | The geometry to draw. |
| inCullMode | determines which polygons are culled. |
| inCastShadow | determines if this geometry should cast a shadow or not. |
| inDrawMode | determines if we draw the geometry solid or in wireframe. |
Implements DebugRenderer.

inlineoverridevirtual |
Fallback implementation that uses DrawLine to draw a triangle (override this if you have a version that renders solid triangles)
Implements DebugRenderer.
Should be called every frame by the application to provide the camera position. This is used to determine the correct LOD for rendering.
