Functions | |
| WlzThreeDViewStruct * | WlzMake3DViewStructCopy (WlzThreeDViewStruct *given, WlzErrorNum *dstErr) |
| Allocates and intialises a new 3D view and sets it's parameters to those of the given view. The new transform's look up tables are not allocated. More... | |
| WlzThreeDViewStruct * | WlzMake3DViewStruct (WlzObjectType type, WlzErrorNum *dstErr) |
| Allocates and intialises a 3D view. The transform look up tables are not allocated. More... | |
| WlzErrorNum | WlzFree3DViewStruct (WlzThreeDViewStruct *viewStr) |
| Frees a view. More... | |
| WlzErrorNum | WlzInit3DViewStructAffineTransform (WlzThreeDViewStruct *viewStr) |
| Sets up the affine transform of the given view including scale. This does not require any initialisation. The intialisation mask will have the WLZ_3DVIEWSTRUCT_INIT_TRANS bit set. By default the scale parameters are not used. Scaling is enabled by setting bits in the voxelRescaleFlg: setting bit 1 will switch on voxel-size rescaling; setting bit 2 will enable global scaling. More... | |
| WlzErrorNum | Wlz3DViewStructSetupTransformLuts (WlzThreeDViewStruct *viewStr) |
| Sets up the transformation look up tables of the given view. More... | |
| WlzErrorNum | Wlz3DViewStructTransformBB (WlzObject *obj, WlzThreeDViewStruct *viewStr) |
| Set up the min and max vertex values for the transformed space. If the input object is a WLZ_3D_DOMAINOBJ then the bounding box will enclose the transformed bounding box of the input object. If the input object is a WLZ_2D_DOMAINOBJ then it is assumed that this is the transformed section and the min and max valuesa are those of the object itself. These values are padded to account for round-off errors. More... | |
| WlzErrorNum | WlzInit3DViewStruct (WlzThreeDViewStruct *viewStr, WlzObject *obj) |
| Initialises a 3D view with respect to the given view parameters and a 3D object. More... | |
| WlzErrorNum | Wlz3DSectionTransformVtx (WlzDVertex3 *vtx, WlzThreeDViewStruct *viewStr) |
| Transforms a 3D vertex using the section transform overwriting the vertex values. More... | |
| WlzErrorNum | Wlz3DSectionTransformVtxR (WlzThreeDViewStruct *viewStr, WlzDVertex3 vtx, WlzDVertex3 *dstVtx) |

| WlzErrorNum | Wlz3DSectionIncrementDistance (WlzThreeDViewStruct *viewStr, double incr) |
| Increments the distance parameter of a 3D view resetting the look up tables as required. This is provided because changing the distance does not require the rotation matrix and all the look up tables only a single multiply and add per look up table entry instead of 2 multiplies and three adds plus all the y look up tables and the rotation matrix with many trigonometry calculations. More... | |
