Detailed Description

A compact Triangle representation for use with the Mesh class.

Represents a triangle in a mesh. Stores pointers to the mesh structure (mesh) and the indices of its vertices.

Member Function Documentation

bool MeshTriangle::hit (  Ray &  r, HitRecord &  rec, Context &  context )  const [virtual]

Intersect given ray with the surface. Parameters: [in,out]  r  Ray to be intersected. [in,out]  rec  Struct for passed back shading geometry. [in,out]  context  Rendering context. Returns: Returns true if a new closest intersection has been found. Implements Surface.

bool MeshTriangle::shadowHit (  Ray &  r, Context &  context )  const [virtual]

Intersect without visibility ordering or shading geometry. Parameters: [in,out]  r  Ray to be intersected. [in,out]  context  Rendering context. Returns: Returns true if a valid intersection is found. Reimplemented from Surface.

BBox MeshTriangle::boundingBox (  double  time0, double  time1 )  const [virtual]

Calculate the bounding box of the surface. Parameters: [in]  time0  Minimum of time interval being sampled. [in]  time1  Maximum of time interval being sampled. Returns: The bounding box of the object in the interval [time0, time1). Implements Surface.

bool MeshTriangle::overlapsBox (  const BBox &  box  )  const [virtual]

Determine if this surface overlaps the input axis aligned box. Parameters: [in]  box  Bounding box to test against. Returns: False if the surface definitely does not overlap the box. Implements Surface.
