PxVisualizationParameter

Defined in include/PxVisualizationParameter.h

struct PxVisualizationParameter

Debug visualization parameters.

PxVisualizationParameter::eSCALE is the master switch for enabling visualization, please read the corresponding documentation for further details.

Public Types

enum Enum

Values:

enumerator eSCALE

This overall visualization scale gets multiplied with the individual scales.

Setting to zero ignores all visualizations. Default is 0.

The below settings permit the debug visualization of various simulation properties. The setting is either zero, in which case the property is not drawn. Otherwise it is a scaling factor that determines the size of the visualization widgets.

Only objects for which visualization is turned on using setFlag(eVISUALIZATION) are visualized (see PxActorFlag::eVISUALIZATION, PxShapeFlag::eVISUALIZATION, …). Default is 0.

Notes:

to see any visualization, you have to set PxVisualizationParameter::eSCALE to nonzero first.
the scale factor has been introduced because it’s difficult (if not impossible) to come up with a good scale for 3D vectors. Normals are normalized and their length is always 1. But it doesn’t mean we should render a line of length 1. Depending on your objects/scene, this might be completely invisible or extremely huge. That’s why the scale factor is here, to let you tune the length until it’s ok in your scene.
however, things like collision shapes aren’t ambiguous. They are clearly defined for example by the triangles & polygons themselves, and there’s no point in scaling that. So the visualization widgets are only scaled when it makes sense.

Range: [0, PX_MAX_F32)Default: 0

enumerator eWORLD_AXES: Visualize the world axes.

enumerator eBODY_AXES

Visualize a bodies axes.

PxActor.globalPose PxActor

enumerator eBODY_MASS_AXES

Visualize a body’s mass axes.

This visualization is also useful for visualizing the sleep state of bodies. Sleeping bodies are drawn in black, while awake bodies are drawn in white. If the body is sleeping and part of a sleeping group, it is drawn in red.

enumerator eCONTACT_POINT
