List of lookAt() Examples

Examples of lookAt()

com.ardor3d.math.Matrix3.lookAt()
Modifies this matrix to equal the rotation required to point the z-axis at 'direction' and the y-axis to 'up'. @param direction where to 'look' at @param up a vector indicating the local up direction. @return this matrix for chaining
com.ardor3d.math.Quaternion.lookAt()
Modifies this quaternion to equal the rotation required to point the z-axis at 'direction' and the y-axis to 'up'. @param direction where to 'look' at @param up a vector indicating the local up direction. @return this quaternion for chaining.
com.ardor3d.renderer.Camera.lookAt()
A convenience method for auto-setting the frame based on a world position the user desires the camera to look at. It points the camera towards the given position using the difference between that position and the current camera location as a direction vector and the general worldUpVector to compute up and left camera vectors. @param pos where to look at in terms of world coordinates @param worldUpVector a normalized vector indicating the up direction of the world. (often {@link Vector3#UNIT_Y} or{@link Vector3#UNIT_Z})
com.jme.math.Quaternion.lookAt()
com.jme.scene.shape.Arrow.lookAt()
com.jme3.math.Quaternion.lookAt()
lookAt is a convienence method for auto-setting the quaternion based on a direction and an up vector. It computes the rotation to transform the z-axis to point into 'direction' and the y-axis to 'up'. @param direction where to look at in terms of local coordinates @param up a vector indicating the local up direction. (typically {0, 1, 0} in jME.)
com.jme3.renderer.Camera.lookAt()
lookAt is a convienence method for auto-setting the frame based on a world position the user desires the camera to look at. It repoints the camera towards the given position using the difference between the position and the current camera location as a direction vector and the worldUpVector to compute up and left camera vectors. @param pos where to look at in terms of world coordinates @param worldUpVector a normalized vector indicating the up direction of the world.(typically {0, 1, 0} in jME.)
com.jme3.scene.CameraNode.lookAt()
lookAt is a convienence method for auto-setting the quaternion based on a direction and an up vector. It computes the rotation to transform the z-axis to point into 'direction' and the y-axis to 'up'. @param direction where to look at in terms of local coordinates @param up a vector indicating the local up direction. (typically {0, 1, 0} in jME.)
javax.media.j3d.Transform3D.lookAt()
Helping function that specifies the position and orientation of a view matrix. The inverse of this transform can be used to control the ViewPlatform object within the scene graph. @param eye the location of the eye @param center a point in the virtual world where the eye is looking @param up an up vector specifying the frustum's up direction

Examples of com.ardor3d.math.Matrix3.lookAt()
