Detailed Description

a virtual light object for tweaking existing lights in an external 3D rendering context

vtkExternalLight is a virtual light object for tweaking existing lights in an external 3D rendering context. It provides a mechanism to adjust and control parameters of existing lights in an external OpenGL context.

It provides methods to locate and point the light, and set its brightness and color. In addition to the basic infinite distance point light source attributes, you can also specify the light attenuation values and cone angle. These attributes are only used if the light is a positional light.

By default, vtkExternalLight overrides specific light parameters as set by the user. Setting the ReplaceMode to ALL_PARAMS, will set all the light parameter values to the ones set in vtkExternalLight.

Warning: Use the vtkExternalLight object to tweak parameters of lights created in the external context. This class does NOT create new lights in the scene.

Example:: Usage example for vtkExternalLight in conjunction with vtkExternalOpenGLRenderer and ExternalVTKWidget
vtkNew<vtkExternalLight> exLight;

exLight->SetLightIndex(GL_LIGHT0); // GL_LIGHT0 identifies the external light

exLight->SetDiffuseColor(1.0, 0.0, 0.0); // Changing diffuse color

vtkNew<ExternalVTKWidget> exWidget;

vtkExternalOpenGLRenderer* ren =

vtkExternalOpenGLRenderer::SafeDownCast(exWidget->AddRenderer());

ren->AddExternalLight(exLight.GetPointer());
