View

class HPS.View : HPS.Sprocket 

The View class is one of the four core display classes used in a Visualize application. It is meant to be used as part of a display hierarchy along with the Canvas, Layout, and Model objects. The View has a parent Layout and can contain a single Model. The View is meant to represent one particular camera’s view of the scene. Like the other three core objects, the View is backed by a HPS.SegmentKey.

Public Functions

void Assign (HPS.View in_that)

void AttachModel (HPS.Model in_model)

This method automatically adjusts the camera to fit the extents of a segment. Note that this method does not take into account any transformations found between in_segment and the View segment. If there might be transforms between in_segment and the View segment, you can use the version of FitWorld which does not require a parameter, or the version of FitWorld which takes both a SegmentKey and a MatrixKit.

Param in_segment:
	The segment used to calculate the new camera.

HPS.View FitWorld (HPS.SegmentKey in_segment, HPS.MatrixKit in_transform)

Param in_segment:
	The segment used to calculate the new camera.
Param in_transform:
	An optional transform to apply to the segment bounding used to compute the camera. This can be used to ensure that the camera is looking at the geometry in the correct position once any modelling matrices are applied.
