VHTK::VHTKHapticShaderNode Class Reference
[Volume Haptics Nodes]
Detailed Description
The haptic shader makes changes to the processing pipeline of the primitives-based volume haptics generator (VolumeHaptics).The processing pipeline of the volume haptics calculations consists of four steps. First the primitives are collected from all active modes, then the solvers are used to determine the new proxy position after which the force is calculated from the displacement of the proxy relative the probe. The last step is to feed this force back to the haptic instrument. Between each of these steps the intermediate result may be altered or analysed by a haptic shader. Each of the shaders are invoced in each step, however the shader does nothing per default.
Since active haptic shaders are used from the haptics thread, do not delete them! Deactivate the node first and wait a few frames before deleting it.
