Detailed Description

an actual instance of a given triangle-primitmives type; this actual trianlge mesh uses the programs and SBT data associated with its associated TrianglesGeomType, and will "instantiate" these with the vertex arrays, index array, etc, specified in this Geom

Member Typedef Documentation

SP

typedef std::shared_ptr<TrianglesGeom> owl::TrianglesGeom::SP

Constructor & Destructor Documentation

TrianglesGeom()

owl::TrianglesGeom::TrianglesGeom	(	Context *const	context,
		GeomType::SP	geometryType
	)

constructor - create a new (as yet without vertices, indices, etc) instance of given triangles geom type

Member Function Documentation

computeBounds()

void owl::TrianglesGeom::computeBounds

(

box3f

bounds[2]

)

call a cuda kernel that computes the bounds of the vertex buffers

createOn()

RegisteredObject::DeviceData::SP owl::TrianglesGeom::createOn ( const DeviceContext::SP &  device )

override

creates the device-specific data for this group

getDD()

TrianglesGeom::DeviceData & owl::TrianglesGeom::getDD ( const DeviceContext::SP &  device ) const

inline

creates the device-specific data for this group

get reference to given device-specific data for this object

get reference to given device-specific data for this object

setIndices()

void owl::TrianglesGeom::setIndices	(	Buffer::SP	indices,
		size_t	count,
		size_t	stride,
		size_t	offset
	)

set the index buffer; this remains one buffer even if motion blur is enabled.

setVertices()

void owl::TrianglesGeom::setVertices	(	const std::vector< Buffer::SP > &	vertices,
		size_t	count,
		size_t	stride,
		size_t	offset
	)

set the vertex array (if vector size is 1), or set/enable motion blur via multiple time steps, if vector size >= 0

Parameters

count

the number of vertices in each time step

toString()

std::string owl::TrianglesGeom::toString ( ) const

overridevirtual

pretty-print

Reimplemented from owl::Geom.
