Perspective: Project the scene parallel to given view direction
(see below).
Top (X-Y): Sets view direction to (0, 0, 1) so the x-y-plane
is seen from top.
Front (X-Z): Sets view direction to (0, 1, 0).
Right (Y-Z): Sets view direction to (-1, 0, 0)
View Direction: Projection is performed parallel to and in
the same direction as this vector (x, y, z).
Interest: The camera position is calculated by (interest +
view direction*distance).
Distance: Distance of the projection plane
from interest (see above).
Roll: Rotation of the camera around the viewing direction out of
the upward-justification. Value
is given in degrees.
Transform
Camera: All transformation like rotate, scale or translate
is done only virtually and for the whole scene.
Selected Model: Transformations are only done for the selected
geometry.
Locale Coordinate System: Mouse motion is interpreted a
different way when you rotate, translate etc. If you drag the mouse
horizontally the transformation is done as if you would drag the mouse along
the x-axis of the coordinate frame of the world (e.g. if you rotate and drag
the mouse horizontally then the geometry / scene is rotated around the
y-axis of the coordinate frame). If you drag the mouse vertically the
transformation is done as if you would drag the mouse along the y-axis of
the coordinate frame of the world. Try switching on the axis frame (Inspector-Display-Show
Axis Frame) to verify the results.
Front / Back Clipping: Clips everything that is nearer than
near clip and everything that is further away than far clip.
Center: Centers the camera such that the bounding box of all
geometries is centered in the display.
Fit: Combined center with scale such that the geometries
fill a certain amount of the display.
Reset: Resets camera roll, direction and interest settings to initial
values.
Reset All: Resets all transformations etc. to their
default values.
