Palitri Axis3D

Class: AxCamera

AxCamera(context)

new AxCamera(context)

Creates a new camera

Parameters:

Name	Type	Description
`context`	Axis	The context to use for the camera

Source:

Engine/Entities/Camera/AxCamera.js, line 6

Methods

BuildMatrix(transform)

Builds the camera transformation matrix, based on a parent transform

Parameters:

Name	Type	Description
`transform`	AxMatrix	The parent transform on which to build the camera's own transform.

Source:

Engine/Entities/Camera/AxCamera.js, line 53

CastVector(screenCoords) → {AxVector3}

Returns a vector which projects from given coordinates on the camera screen into scene space. The returned vector is normalized Camera must have its matrices built in order for this method to work. This should normally not be an issue, since matrices of the camera are built by the BuildMatrix method, which is routinely called. If needed, call BuildMatrix() explicitly before calling this method.

Parameters:

Name	Type	Description
`screenCoords`	AxVecto2	The coordinates of the point on the screen, from which to project the ray. The coordinates must be in the range [-1, 1] from left to right and from bottom to top of the screen

Source:

Engine/Entities/Camera/AxCamera.js, line 132

Returns:

A normalized vector, oriented along a point on the camera screen

Type: AxVector3

GetPixelSpaceCoords(worldPos) → {AxVector2}

Calculates the projected 2D coordinates on screen for a 3D point in space. Coordinates are in screen space, in the interval [-1, 1]

Parameters:

Name	Type	Description
`worldPos`	AxVector3

Source:

Engine/Entities/Camera/AxCamera.js, line 118

Returns:

Type: AxVector2

GetScreenSpaceCoords(worldPos) → {AxVector2}

Calculates the projected 2D coordinates on screen for a 3D point in space. Coordinates are in pixel space

Parameters:

Name	Type	Description
`worldPos`	AxVector3

Source:

Engine/Entities/Camera/AxCamera.js, line 105

Returns:

Type: AxVector2

ProjectVector(vector) → {AxVector3}

Returns a vector which is projected onto the camera screen from given point in scene space Camera must have its matrices built in order for this method to work. This should normally not be an issue, since matrices of the camera are built by the BuildMatrix method, which is routinely called. If needed, call BuildMatrix() explicitly before calling this method.

Parameters:

Name	Type	Description
`vector`	AxVector3	The coordinates of a vector in scene space

Source:

Engine/Entities/Camera/AxCamera.js, line 146

Returns:

The screen space coordinates of the vector, projected onto the camera screen. Coordinates are between the range [-1, 1] from left to right, bottom to top and back to forward

Type: AxVector3
