This class provides information about a single node being rendered.
This includes information such as the mesh of the object, its material, unique node ID, object space bounding extents, number of lights affecting it, material requirements, and normals and vertex coordinates in various spaces (object and camera).
- Data Members:
- ULONG flags;
The flags that describe the properties of this instance. See Render Instance Flags .
Mtl *mtl;
This is the material from the node.
float wireSize;
The wireframe size.
Mesh *mesh;
The mesh to be rendered. This is the result of GeomObject::GetRenderMesh().
float vis;
Object visibility (between 0.0 and 1.0). This is the value the visibility track evaluates to at a particular time.
int nodeID;
A unique ID associated with the node. It's unique within the scene during a render.
int objMotBlurFrame;
This will be equal to NO_MOTBLUR for all non-blurred objects. For blurred objects, it takes on the values (0..nBlurFrames-1) for the successive blur-instances.
int objBlurID;
The purpose of this is to differentiate blur-instances generated from different nodes. All the blur-instances for an object-motion-blurred object will have the same objBlurID. This is as distinct from nodeID, which is different for every instance. This makes it possible to easily avoid intersecting a ray with all blur-instances for an object. If RenderGlobalContext::IntersectWorld() is being used, then passing in the objBlurID for the parameter skipID will have this effect.
The basic technique is this: When reflecting or refracting rays, and object motion blur is enabled, choose sub-frame times randomly for the different rays (effectively giving a coarse stochastic sampling of time).
Matrix3 objToWorld;
This matrix can be used to transform object coordinates to world coordinates.
Matrix3 objToCam;
This matrix can be used to transform object coordinates to camera coordinates.
Matrix3 normalObjToCam;
This matrix can be used for transforming surface normals from object space to camera space.
Matrix3 camToObj;
This matrix can be used to transform camera coordinates to object coordinates.
Box3 obBox;
The object space extents of the object being rendered.
Point3 center;
The object bounding sphere center (in camera coordinates)
float radsq;
The square of the bounding sphere's radius.
