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
exLight->SetLightIndex(GL_LIGHT0); // GL_LIGHT0 identifies the external light
exLight->SetDiffuseColor(1.0, 0.0, 0.0); // Changing diffuse color
vtkExternalOpenGLRenderer::SafeDownCast(exWidget->AddRenderer());
ren->AddExternalLight(exLight.GetPointer());
virtual void AddExternalLight(vtkExternalLight *)
Add an external light to the list of external lights.
static vtkExternalOpenGLRenderer * SafeDownCast(vtkObjectBase *o)
Allocate and hold a VTK object.
Definition: vtkNew.h:160
T * GetPointer() const noexcept
Get a raw pointer to the contained object.

Reimplemented from vtkLight.

◆ New()

static vtkExternalLight* vtkExternalLight::New ( )
static

Create an external light object with the focal point at the origin and its position set to (0,0,1).

The light is a Headlight, its color is white (black ambient, white diffuse, white specular), intensity=1, the light is turned on, positional lighting is off, ConeAngle=30, AttenuationValues=(1,0,0), Exponent=1 and the TransformMatrix is NULL. The light index is GL_LIGHT0, which means the existing light with index GL_LIGHT0 will be affected by this light.
