Detailed Description

Representation of a dynamic light source in the scene.

Remarks:
Lights are added to the scene like any other object. They contain various parameters like type, position, attenuation (how light intensity fades with distance), colour etc.

The defaults when a light is created is pure white diffues light, with no attenuation (does not decrease with distance) and a range of 1000 world units.

Lights are created by using the SceneManager::createLight method. They can subsequently be added to a SceneNode if required to allow them to move relative to a node in the scene. A light attached to a SceneNode is assumed to havea base position of (0,0,0) and a direction of (0,0,1) before modification by the SceneNode's own orientation. If not attached to a SceneNode, the light's position and direction is as set using setPosition and setDirection.

Remember also that dynamic lights rely on modifying the colour of vertices based on the position of the light compared to an object's vertex normals. Dynamic lighting will only look good if the object being lit has a fair level of tesselation and the normals are properly set. This is particularly true for the spotlight which will only look right on highly tesselated models. In the future OGRE may be extended for certain scene types so an alternative to the standard dynamic lighting may be used, such as dynamic lightmaps.

Member Enumeration Documentation

enum Ogre::Light::LightTypes
 

Defines the type of light.

Enumeration values:
LT_POINT  Point light sources give off light equally in all directions, so require only position not direction.
LT_DIRECTIONAL  Directional lights simulate parallel light beams from a distant source, hence have direction but no position.
LT_SPOTLIGHT  Spotlights simulate a cone of light from a source so require position and direction, plus extra values for falloff.

Member Function Documentation

const PlaneBoundedVolumeList & Ogre::Light::_getFrustumClipVolumes const Camera   cam const
 

Internal method for calculating the clip volumes outside of the frustum which can be used to determine which objects are casting shadow on the frustum as a whole.

Remarks:
Each of the volumes is a pyramid for a point/spot light and a cuboid for a directional light.

Remarks:
This volume is a pyramid for a point/spot light and a cuboid for a directional light. It can used to detect whether an object could be casting a shadow on the viewport. Note that the reference returned is to a shared volume which will be reused across calls to this method.

void Ogre::ShadowCaster::extrudeVertices HardwareVertexBufferSharedPtr    vertexBuffer,
size_t    originalVertexCount,
const Vector4   lightPos,
Real    extrudeDist
[static, inherited]
 

Utility method for extruding vertices based on a light.

Remarks:
Unfortunately, because D3D cannot handle homogenous (4D) position coordinates in the fixed-function pipeline (GL can, but we have to be cross-API), when we extrude in software we cannot extrude to infinity the way we do in the vertex program (by setting w to 0.0f). Therefore we extrude by a fixed distance, which may cause some problems with larger scenes. Luckily better hardware (ie vertex programs) can fix this.
Parameters:
vertexBuffer  The vertex buffer containing ONLY xyz position values, which must be originalVertexCount * 2 * 3 floats long.
originalVertexCount  The count of the original number of vertices, ie the number in the mesh, not counting the doubling which has already been done (by VertexData::prepareForShadowVolume) to provide the extruded area of the buffer.
lightPos  4D light position in object space, when w=0.0f this represents a directional light
extrudeDist  The distance to extrude

Parameters:
edgeData  The edge information to use
indexBuffer  The buffer into which to write data into; current contents are assumed to be discardable.
light  The light, mainly for type info as silhouette calculations should already have been done in updateEdgeListLightFacing
shadowRenderables  A list of shadow renderables which has already been constructed but will need populating with details of the index ranges to be used.
flags  Additional controller flags, see ShadowRenderableFlags

Vector4 Ogre::Light::getAs4DVector void    const
 

Gets the details of this light as a 4D vector.

Remarks:
Getting details of a light as a 4D vector can be useful for doing general calculations between different light types; for example the vector can represent both position lights (w=1.0f) and directional lights (w=0.0f) and be used in the same calculations.

void Ogre::Light::setAttenuation Real    range,
Real    constant,
Real    linear,
Real    quadratic
 

Sets the attenuation parameters of the light source ie how it diminishes with distance.

Remarks:
Lights normally get fainter the further they are away. Also, each light is given a maximum range beyond which it cannot affect any objects.

Light attentuation is not applicable to directional lights since they have an infinite range and constant intensity.

This follows a standard attenuation approach - see any good 3D text for the details of what they mean since i don't have room here!

Parameters:
range  The absolute upper range of the light in world units
constant  The constant factor in the attenuation formula: 1.0 means never attenuate, 0.0 is complete attenuation
linear  The linear factor in the attenuation formula: 1 means attenuate evenly over the distance
quadratic  The quadratic factor in the attenuation formula: adds a curvature to the attenuation formula.

void Ogre::MovableObject::setCastShadows bool    enabled [inherited]
 

Sets whether or not this object will cast shadows.

Remarks:
This setting simply allows you to turn on/off shadows for a given object. An object will not cast shadows unless the scene supports it in any case (see SceneManager::setShadowTechnique), and also the material which is in use must also have shadow casting enabled. By default all entities cast shadows. If, however, for some reason you wish to disable this for a single object then you can do so using this method.
Note:
This method normally refers to objects which block the light, but since Light is also a subclass of MovableObject, in that context it means whether the light causes shadows itself.

void Ogre::Light::setDiffuseColour const ColourValue   colour
 

Sets the colour of the diffuse light given off by this source.

Remarks:
Material objects have ambient, diffuse and specular values which indicate how much of each type of light an object reflects. This value denotes the amount and colour of this type of light the light exudes into the scene. The actual appearance of objects is a combination of the two.

Diffuse light simulates the typical light emenating from light sources and affects the base colour of objects together with ambient light.

virtual void Ogre::MovableObject::setQueryFlags unsigned long    flags [virtual, inherited]
 

Sets the query flags for this object.

Remarks:
When performing a scene query, this object will be included or excluded according to flags on the object and flags on the query. This is a bitwise value, so only when a bit on these flags is set, will it be included in a query asking for that flag. The meaning of the bits is application-specific.

Definition at line 170 of file OgreMovableObject.h.

void Ogre::MovableObject::setRenderQueueGroup RenderQueueGroupID    queueID [virtual, inherited]
 

Sets the render queue group this entity will be rendered through.

Remarks:
Render queues are grouped to allow you to more tightly control the ordering of rendered objects. If you do not call this method, all Entity objects default to RENDER_QUEUE_MAIN which is fine for most objects. You may want to alter this if you want this entity to always appear in front of other objects, e.g. for a 3D menu system or such.

See RenderQueue for more details.

Parameters:
queueID  Enumerated value of the queue group to use.

void Ogre::Light::setSpecularColour const ColourValue   colour

Remarks:
Material objects have ambient, diffuse and specular values which indicate how much of each type of light an object reflects. This value denotes the amount and colour of this type of light the light exudes into the scene. The actual appearance of objects is a combination of the two.

Specular light affects the appearance of shiny highlights on objects, and is also dependent on the 'shininess' Material value.
