Member Function Documentation

const wxString VRUT::Geometry::GetName ( ) const [inline]

Get name.

Definition at line 65 of file geometry.h.

00066               {
00067                      return name;
00068               }

const AABB& VRUT::Geometry::GetAABB ( ) const [inline]

Get AABB.

Definition at line 70 of file geometry.h.

00071               {
00072                      return aabb;
00073               }

virtual void VRUT::Geometry::BuildAABB ( ) [pure virtual]

Build AABB.

Implemented in VRUT::GeometryTriangles.

virtual bool VRUT::Geometry::Intersects	(	const Ray &	ray,
		float *	dist = `(float *) NULL`
	)			const `[pure virtual]`

Check if ray intersects geometry, get intersection point distance from ray origin if it does NOTE: everything must be in one space (model space by default), dist will be in that space too!

Implemented in VRUT::GeometryTriangles.

virtual bool VRUT::Geometry::CastRay	(	const Ray &	ray,
		RayIntersectionInfo &	info
	)			const `[inline, virtual]`

Cast ray towards the geometry, get intersection info if it does NOTE: everything must be in one space (model space by default), intersection info will be in that space too!

Reimplemented in VRUT::GeometryTriangles.

Definition at line 83 of file geometry.h.

00083                                                                                 {
00084               // not pure virtual for now !
00085               return false;
00086          }

virtual std::vector<Triangle> VRUT::Geometry::Triangulate ( ) const [pure virtual]

Get geometry as list of triangles.

Implemented in VRUT::GeometryTriangles.

virtual void VRUT::Geometry::AddBox	(	const vector3 &	position,
		const vector3 &	size
	)			`[pure virtual]`

Add Box to geometry.

Implemented in VRUT::GeometryTriangles.

virtual wxString VRUT::Geometry::ToString ( ) const [inline, virtual]

Get string with geometry properties.

Reimplemented in VRUT::GeometryTriangles.
