Public Member Functions | |
| ~FlowGeometry () | |
| deletes the allocated geometry storage | |
| bool | IsFlipped () |
| void | getMesh (std::vector< float > &xdiff, std::vector< float > &ydiff) |
| bool | getInterpolationAt (vec3 pos, int *vtxID, float *coef) |
| Returns true if inside. Stores the vertex indices and interpolation weights for the given position in the arrays. | |
| bool | readFromFile (char *header, FILE *fp, bool bigEndian) |
| reads the geometry gris data from a file | |
| int | getDimX () |
| returns the number of vertices in X dimension | |
| int | getDimY () |
| returns the number of vertices in Y dimension | |
| int | getDimZ () |
| returns the number of vertices in Z dimension, is always 1 | |
| float | getMinX () |
| returns the minimum in the X dimension | |
| float | getMaxX () |
| returns the maximum in the X dimension | |
| float | getMinY () |
| returns the minimum in the Y dimension | |
| float | getMaxY () |
| returns the maximum in the Y dimension | |
| int | getRightNeigh (int vtxID) |
| returns the vertex ID of the neighbour on its right | |
| int | getTopNeigh (int vtxID) |
| returns the vertex ID of the neighbour on its top | |
| int | getLeftNeigh (int vtxID) |
| returns the vertex ID of the neighbour on its left | |
| int | getBottomNeigh (int vtxID) |
| returns the vertex ID of the neighbour on its bottom | |
| vec3 | normalizeCoords (vec3 pos) |
| compression of coordinates in each dimension separately, returns values scaled to <0,1> | |
| vec3 | unNormalizeCoords (vec3 pos) |
| inverts the compression. From values of <0,1> it restores the real geometrical coordinates | |

| bool FlowGeometry::getInterpolationAt | ( | vec3 | pos, |
| int * | vtxID, | ||
| float * | coef | ||
| ) |
Returns true if inside. Stores the vertex indices and interpolation weights for the given position in the arrays.
Stores the indexes and weights of vertices surrounding the given position. This information can be used later on for interpolation of channel values.
| pos | geometrical position for the lookup |
| vtxID | list of surrounding vertices (given by vertex ID) |
| coef | list of surrounding vertex weights (sum == 1.0) |
