Description
|
Checks whether the vision sensor detects the indicated entity. This is the extended functionality version of sim.checkVisionSensor. Detection is silent (no visual feedback) compared to sim.handleVisionSensor. The vision callback functions will be called on the acquired image. Also, the visibility state of the entity is overridden if the entity is an object. See also sim.readVisionSensor.

synopsis
|
simFloat* simCheckVisionSensorEx(simInt sensorHandle,simInt entityHandle,simBool returnImage)
|
C/C++
parameters |
sensorHandle: handle of the vision sensor object
entityHandle: handle of entity to detect (object or collection), or sim.handle_all to detect all detectable objects
returnImage: specifies what should be returned. If true, the sensor's image buffer is returned, otherwise its depth buffer is returned
|
C/C++
return value
|
image or depth buffer, or nullptr in case of an error. The user is in charge of releasing the returned buffer with simReleaseBuffer

Lua
parameters |
sensorHandle: handle of the vision sensor object. Can be combined with sim.handleflag_codedstring if you wish to retrieve the image or depth map coded in a string (much faster).
entityHandle: Similar to the C-function counterpart
returnImage: Similar to the C-function counterpart

Lua
return values
|
Similar to the C-function counterpart: a table containing the image or depth buffer is returned
