Method Detail

set

public void set(CameraParameters params)

setPosition

public void setPosition(Vec3f position)

Sets 3-space origin of camera

getPosition

public Vec3f getPosition()

Gets 3-space origin of camera

setForwardDirection

public void setForwardDirection(Vec3f fwd)

Sets 3-space forward direction of camera. Does not need to be normalized.

getForwardDirection

public Vec3f getForwardDirection()

Gets 3-space forward direction of camera.

setUpDirection

public void setUpDirection(Vec3f up)

Sets 3-space upward direction of camera. This must be orthogonal to the viewing direction, but does not need to be normalized.

getUpDirection

public Vec3f getUpDirection()

Gets 3-space upward direction of camera.

setVertFOV

public void setVertFOV(float vertFOV)

Takes HALF of the vertical angular span of the frustum, specified in radians. For example, if your fovy argument to gluPerspective() is 90, then this would be M_PI / 4.

getVertFOV

public float getVertFOV()

Returns HALF of the vertical angular span of the frustum, specified in radians.

setImagePlaneAspectRatio

public void setImagePlaneAspectRatio(float ratio)

Sets the aspect ratio of the image plane. Note that this does not necessarily have to correspond to the aspect ratio of the window.

getImagePlaneAspectRatio

public float getImagePlaneAspectRatio()

Gets the aspect ratio of the image plane.

setXSize

public void setXSize(int xSize)

Sets the horizontal size of the window, in pixels

getXSize

public int getXSize()

Gets the horizontal size of the window, in pixels

setYSize

public void setYSize(int ySize)

Sets the vertical size of the window, in pixels

getYSize

public int getYSize()

Gets the vertical size of the window, in pixels
