RadialDistortionPass

Source (.js)Source (.d.ts)

Methods

buildVBO

Build the distorted grid the delegate output is drawn onto. The grid is two side-by-side halves, one per eye, whose texture coordinates carry the radial distortion. Also recomputes the render ratio from k1 and k2.

extend

Method used to decorate a given object (publicAPI+model) with vtkRadialDistortionPass characteristics.

Argument	Type	Required	Description
publicAPI		Yes	object on which methods will be bounds (public)
model		Yes	object on which data structure will be bounds (protected)
initialValues	IRadialDistortionPassInitialValues	No	(default: {})

getCameraCenterX1

Get the x coordinate of the left half's distortion center, in normalized device coordinates.

getCameraCenterX2

Get the x coordinate of the right half's distortion center, in normalized device coordinates.

getCameraCenterY

Get the y coordinate of the distortion center, in normalized device coordinates.

getFramebuffer

Get the framebuffer the delegate passes render into, or null before the first traversal.

getK1

Get the second-order radial distortion coefficient.

getK2

Get the fourth-order radial distortion coefficient.

newInstance

Method used to create a new instance of vtkRadialDistortionPass.

Argument	Type	Required	Description
initialValues	IRadialDistortionPassInitialValues	No	for pre-setting some of its content

setCameraCenterX1

Set the x coordinate of the left half's distortion center.

Argument	Type	Required	Description
cameraCenterX1	Number	Yes

setCameraCenterX2

Set the x coordinate of the right half's distortion center.

Argument	Type	Required	Description
cameraCenterX2	Number	Yes

setCameraCenterY

Set the y coordinate of the distortion center.

Argument	Type	Required	Description
cameraCenterY	Number	Yes

setK1

Set the second-order radial distortion coefficient. With both k1 and k2 at zero the pass is a no-op and simply forwards to its delegates.

Argument	Type	Required	Description
k1	Number	Yes

setK2

Set the fourth-order radial distortion coefficient.

Argument	Type	Required	Description
k2	Number	Yes
