Functions in detail

Geometry.applyTransform! ( in Mat44 transform )

Transforms the positions of the geometry (and normals if applicable)

---

Geometry.applyTransform! ( in Xfo transform )

Transforms the positions of the geometry (and normals if applicable)

---

Geometry.convertToCPU! ()

---

Geometry.convertToGPU! ()

---

Geometry.copy! ( in Geometry src )

Copies all the data from source Geometry, including attributes.

---

Size Geometry.elementCount? ()

Returns the number of elements for this Geometry. Elements are geometry specific: polygons for PolygonMesh, line segments for Lines, points for Points...

---

Vec3[] Geometry.getAllPointPositions? ()

Returns all point positions

---

Ref<GeometryAttributes> Geometry.getAttributes? ()

Returns the associated attribute container, if any.

注釈

the usage and meaning of attribute values is geometry specific.

---

LocalBoundingVolume Geometry.getBoundingVolume? ()

Returns the local bounding volume of the geometry (typically a bounding box around the point positions)

---

String Geometry.getDebugName? ()

Returns the debug name used when constructing the geometry.

---

String Geometry.getDesc? ( in Boolean withAttributes, in Boolean useUnitTestPrint )

Returns a description of the Geometry.

withAttributes	If true, will print all attributes and their values
useUnitTestPrint	If true, floats will use a numerically stable, unit test friendly output

---

LocalBoundingVolume Geometry.getElementBoundingVolume? ( in Size index )

Returns the bounding volume of an element. Elements are geometry specific: polygons for PolygonMesh, line segments for Lines, points for Points...

---

UInt32 Geometry.getMemType? ()

Returns the memory location id. CPU = 0, GPU = 1, VSM = 2;

---

Ref<ThreadsafeMetaDataContainer> Geometry.getMetaData? ()

Returns the metaData container for this Geometry.

---

Vec3 Geometry.getPointPosition? ( in Size point )

Returns the position of a point.

---

UInt32 Geometry.getStructureVersion? ()

Returns the version of the geometry structure including the the attribute set (but not attribute values).

---

UInt32 Geometry.getVersion? ()

Returns the version of the geometry including attribute values

---

Size Geometry.pointCount? ()

Returns the number of points.

---

Geometry.setAllPointPositions! ( in Vec3 positions[] )

Sets all point positions

---

Geometry.setPointPosition! ( in Size point, in Vec3 position )

Sets the positions of a point.
