Detailed Description

Classes for performing 3D math calculations.

These classes should be helpful for most basic 3D math calculations, from finding dot and cross products to line-triangle intersections.

Typedef Documentation

typedef float GAUGE3D::GCoordinate

Represents a coordinate. This type should be used in all 3D math functions and any functions that manipulate positions in three dinemtional space.

Variable Documentation

const GVector GAUGE3D::GVECTOR_FORWARD = GVector(0.0, 1.0, 0.0)

Vector pointing in the "forward" direction. In GAUGE, the positive Y axis points forward.

const GVector GAUGE3D::GVECTOR_RIGHT = GVector(1.0, 0.0, 0.0)

Vector pointing in the "up" direction. In GAUGE, the positive X axis points right.

const GVector GAUGE3D::GVECTOR_UP = GVector(0.0, 0.0, 1.0)

Vector pointing in the "right" direction. In GAUGE, the positive Z axis points up.
