Setup a Point Light

A point light originates from a single position and spreads outward in all directions.

First you need to create the light using the factory:

// Create the light shape:
RED::Object* light = RED::Factory::CreateInstance( CID_REDLightShape );
if( light == NULL )
    RC_TEST( RED_ALLOC_FAILURE );

RED::ILightShape* ilight = light->As< RED::ILightShape >();

Then you define the point light:

// The point light parameters:
RED::Vector3 position = RED::Vector3( 20.0, 20.0, 60.0 );
RED::Color diffuse = RED::Color::WHITE;
RED::Color specular = RED::Color::WHITE;
float att_values[7] = { 1.f, 0.f, 0.f, 0.f, 0.f, 0.f, 0.f };

// Define the light as point:
RC_TEST( ilight->SetPointLight( RED::ATN_NONE, att_values, position, diffuse, specular, iresmgr->GetState() ) );

See the Decay Equations chapter to learn about light attenuation modes and settings.

Finally you add the light to the camera:

// Add the scene data to the viewpoint:
RC_TEST( icamera->AddShape( light, iresmgr->GetState() ) );
