Detailed Description

Stores information about a single splat.

In addition to the location inherited from Entity, a splat also contains information about its normal, color and the u and v axes. The length of the vectors u and v are the inverse of the scalar ellipse parameters u and v.

Constructor & Destructor Documentation

Splat::Splat

(

)

Creates a Splat with default values.

The splat is located at the origin, with normal vector (0,0,1), u is (1,0,0) and v is (0,1,0). Its color is set to white.

Splat::Splat

(

Entity &

entity

)

Creates a Splat at the given location.

The normal vector is initialized with (0,0,1), u is (1,0,0) and v is (0,1,0). The color is set to white.

Parameters

entity

An entity providing the location information for the new splat.

Member Function Documentation

void Splat::adaptUvToNormal

(

)

Adapts u and v to the normal.

This method expects that u, v and n are already orthogonal. It adapts the direction of u so that the cross product of u and v points in n direction.
