There are many tools which can be used to change the viewing angle of a perspective:
- magnifying lens for enlarging and reducing
- rotating the view
- shift of perspective
- moving through the scene
As well as these quite obvious tools there are also some which are concealed:
- combination of magnifying glass and Ctrl =
If the mouse is moved vertically while the left button and Ctrl are depressed, the focal point of the camera perspective is shifted. In this way the same focal point can improve the attraction of a perspective. And of course ray tracing can also be created with the newly set perspective. - Rotating + Alt = shift of perspective
- Moving through + Ctrl = changing the eye level in the perspective
- Moving through + Shift = changing the viewing direction in the perspective
