Detailed Description

Information about data returned for an arbitrary plane.

Used with the SoLDMDataAccess::getData(int, const SbBox3i32&, const SbPlane&, SoBufferObject*) method.

The following figure shows the information that is returned.

Member Data Documentation

◆ bufferDimension

SbVec2i32 SoLDMDataAccess::DataInfoPlane::bufferDimension

Dimension of the 2D data matrix (in voxels).

The dimension depends on the resolution.

Definition at line 465 of file SoLDMDataAccess.h.

◆ bufferSize

int64_t SoLDMDataAccess::DataInfoPlane::bufferSize

Size of the requested data in bytes.

Used by the application to allocate buffer.

Definition at line 463 of file SoLDMDataAccess.h.

◆ errorFlag

ErrorValue SoLDMDataAccess::DataInfoPlane::errorFlag

Error indicator.

Use enum ErrorValue. Note that even when errorFlag is CORRECT, bufferSize may be zero meaning no data was returned.

Definition at line 461 of file SoLDMDataAccess.h.

◆ numPolygonPoints

int SoLDMDataAccess::DataInfoPlane::numPolygonPoints

Number of points of the polygon intersecting subvolume.

The polygon will have 3, 4, 5, or 6 vertices depending on how the plane intersects the subvolume.

Definition at line 470 of file SoLDMDataAccess.h.

◆ polygonCoord

SbVec3i32 SoLDMDataAccess::DataInfoPlane::polygonCoord[6]

Polygon intersecting subvolume in voxel coordinates.

Definition at line 472 of file SoLDMDataAccess.h.

◆ quadCoord

SbVec3i32 SoLDMDataAccess::DataInfoPlane::quadCoord[4]

Quad corresponding to the returned data in voxel coordinates.

Definition at line 474 of file SoLDMDataAccess.h.

◆ uAxis

int SoLDMDataAccess::DataInfoPlane::uAxis

Axis corresponding to the first dimension of the returned array.

0 = x, 1 = y, 2 = z.

Definition at line 478 of file SoLDMDataAccess.h.

◆ vAxis

int SoLDMDataAccess::DataInfoPlane::vAxis

Axis corresponding to the second dimension of the returned array.
