Method Details

cameraClampInclineDisable

void cameraClampInclineDisable()

Do not clamp rotations around the horizontal axis.

See Also:

• cameraClampInclineEnable(double, double)

cameraClampInclineEnable

void cameraClampInclineEnable(double min,
 double max)

Clamp the possible rotations around the horizontal axis to the given bounds.

Parameters:

min - The minimum angle

max - The maximum angle

cameraClampRadiusDisable

void cameraClampRadiusDisable()

Do not clamp the length of the radius.

See Also:

• cameraClampRadiusEnable(double, double)

cameraClampRadiusEnable

void cameraClampRadiusEnable(double min,
 double max)

Clamp the length of the radius to the given bounds.

Parameters:

min - The minimum length

max - The maximum length

cameraMoveTargetForwardOnXZ

void cameraMoveTargetForwardOnXZ(double u)

Move the target point of the camera forward u units iff u is positive, or backward u units iff u is negative.

The forward direction, in this case, means the current view direction projected onto the X/Z plane. This means that the camera will not move along the Y axis.

Parameters:

u - The units to move

cameraMoveTargetRight

void cameraMoveTargetRight(double u)

Move the target point of the camera right u units iff u is positive, or left u units iff u is negative.

The right direction, in this case, means the direction perpendicular to the current view direction, -π / 2 radians around the global Y axis.

Parameters:

u - The units to move

cameraMoveTargetUp

void cameraMoveTargetUp(double u)

Move the target point of the camera up u units iff u is positive, or down u units iff u is negative.

The up direction, in this case, means the direction towards positive infinity on the global Y axis.

Parameters:

u - The units to move

cameraOrbitHeading

void cameraOrbitHeading(double r)

Parameters:

r - The radians to rotate

cameraOrbitIncline

boolean cameraOrbitIncline(double r)

Parameters:

r - The radians to orbit

Returns:

true if the rotation has been clamped

See Also:

• cameraClampInclineEnable(double, double)

cameraSetAngleHeading

void cameraSetAngleHeading(double a)

Set the heading angle to a.

Parameters:

a - The angle.

cameraSetAngleIncline

void cameraSetAngleIncline(double a)

Set the incline angle to a.

Parameters:

a - The angle.

cameraSetTargetPosition

void cameraSetTargetPosition(com.io7m.jtensors.core.unparameterized.vectors.Vector3D v)

Set the position of the target point of camera.

Parameters:

v - The position.

cameraSetTargetPosition3

void cameraSetTargetPosition3(double x,
 double y,
 double z)

Set the position of the target point of camera.

Parameters:

x - The x coordinate.

y - The y coordinate.

z - The z coordinate.

cameraSetZoom

void cameraSetZoom(double r)

Set the zoom (or radius) of the camera to r.

Parameters:

r - The camera radius.

cameraZoomIn

boolean cameraZoomIn(double r)

Zoom in the camera by reducing the radius of the sphere.

Parameters:

r - The amount by which to reduce the radius

Returns:

true if the radius has been clamped

See Also:

• cameraClampRadiusEnable(double, double)

cameraZoomOut

boolean cameraZoomOut(double r)

Zoom out the camera by increasing the radius of the sphere.

Parameters:

r - The amount by which to increase the radius

Returns:

true if the radius has been clamped

• cameraClampRadiusEnable(double, double)
