Field |
Description |
Access to the TAnimation structure. | |
Access to the TColordialog component | |
Type of attribute that is handled by this transfer function - direction, speed,... | |
unused | |
Number of node, that is being dragged. Default = -1. | |
Access to the TDataSet structure. | |
Access to the TFlow structure. | |
Texture data of the global histogram texture. | |
True if the global histogram (all timesteps in one) is shown. | |
Pointer to the texture of the global histogram | |
Pointer to the mesh of transfer node | |
Texture data of histogram textures for all time steps | |
Histogram values for single time steps. | |
Histogram values for the global historagm | |
Histogram texture pointers for all the time steps. | |
Pointer to the mesh of transfer node | |
Pointer to the mesh of transfer node | |
Number of node, that is selected. Default = -1. | |
If false, only the transfer functino is drawn. | |

Method |
Description |
Transforms TColor value to a 3d vector of <0..1> | |
Constructor, creates default transfer functions. | |
Deletes texture, when switched to another TTF instance. | |
Deletes selected transfer node. | |
Destructor. Frees memory. | |
Determines color of a point form <0..1> | |
Checks if a swapped histogram texture from previous usage of the dataset exists. | |
Saves data for creation of the histogram texture for one time step. | |
If no data swapped, this generates the global histogram texture data. | |
If no data swapped, this generates the histogram texture data for one tiome step. | |
Initializes the histogram and transfer node meshes (display lists) | |
Loads a lit of transfer nodes form a file | |
Draw routine called one per frame. | |
MouseUp handler | |
Checks if there is a transfer node under the mouse pointer | |
Resets the transfer function to it default. | |
Saves data to be swapped to HDD. | |
Saves the array of transfer nodes to a file | |
Makes the transfer function visible and loads the textures to graphical memory. | |
Sorts the transfer nodes by their position | |
Determines, if the mouse clicked into the transfer node i. | |
makes no node selected |
