.SH "Detailed Description"
.PP 
The \fBSoLight\fP class is the base class for light emitting nodes\&. 

This node type is abstract and does not in itself provide any light sources to the scene, you need to use one of its subclasses\&.

.PP
There are a few important things to know about light sources in Coin\&. First of all, the more light sources you have in your scene, the slower the rendering will be\&. The impact on rendering speed is highly dependent on the graphics hardware and/or rendering subsystem software implementation (i\&.e\&. how optimized an OpenGL you or your users are running), but it could be severe\&.

.PP
Another issue which is important to know is that OpenGL rendering engines usually have a fixed maximum number of available light sources which can be present in the state at the same time\&. If you reach the maximum number, further light sources will simply be ignored\&. The maximum number of light sources for OpenGL rendering can be found by using:

.PP
.PP
.nf
#include <Inventor/elements/SoGLLightIdElement\&.h>
#include <Inventor/nodes/SoSubNodeP\&.h>
// \&.\&.\&.[snip]\&.\&.\&.
int nrlights = SoGLLightIdElement::getMaxGLSources();
.fi
.PP

.PP
If you are clever with how you use light sources, you can get away with using a lot more lights in a scene graph than the max available from the rendering system\&. This is because light sources are stacked on the traversal state, just like other appearance data\&. So if you put light sources under \fBSoSeparator\fP nodes, they will be popped off and 'forgotten' for the remaining geometry of the scene graph after the subgraph below an \fBSoSeparator\fP has been traversed\&.

Returns the type identification of an object derived from a class inheriting \fBSoBase\fP\&. This is used for runtime type checking and 'downward' casting\&.

.PP
Implements \fBSoBase\fP\&.

.br
 
.SS "const \fBSoFieldData\fP * SoLight::getFieldData (void ) const\fR [protected]\fP, \fR [virtual]\fP"

Reimplemented in \fBSoDirectionalLight\fP, \fBSoDirectionalLightManip\fP, \fBSoPointLight\fP, \fBSoPointLightManip\fP, \fBSoShadowDirectionalLight\fP, \fBSoShadowSpotLight\fP, \fBSoSpotLight\fP, and \fBSoSpotLightManip\fP\&.
.SS "void SoLight::callback (\fBSoCallbackAction\fP * action)\fR [virtual]\fP"
Action method for \fBSoCallbackAction\fP\&.

Simply updates the state according to how the node behaves for the render action, so the application programmer can use the \fBSoCallbackAction\fP for extracting information about the scene graph\&.

Intensity of light source\&. This decides how much the light source should affect the colors etc of the scene geometry\&. Valid range is 0\&.0 (none) to 1\&.0 (maximum)\&. Default value is 1\&.0\&.
