| - | ====== The Camera Tool ====== | ||
| - | |||
| - | {{mapping:cawe:editingtools:cawe_toolbar_camera.png?80 }} | ||
| - | |||
| - | In section [[mapping:cawe:views]] we have explained how 2D and 3D views work and how you use them to explore and navigate the map. | ||
| - | We have also mentioned (albeit briefly) that each 3D view has a "camera" assigned: | ||
| - | A camera specifies a viewer //origin// (sometimes also called "eye position") and an //orientation// ("direction"). When you use the mouse or keyboard to look, move, pan, zoom or orbit in a 3D view, you actually manipulate the related camera position and orientation, and the 3D view in turn uses the updated camera details to update the scene rendering. | ||
| - | |||
| - | We believe that the mouse and keyboard camera controls of section [[mapping:cawe:views]] are so powerful and easy to use that you will use them virtually all the time. | ||
| - | |||
| - | The purpose of the Camera tool is to add the less frequently needed extras: | ||
| - | You can create new cameras (and assign them in turns to 3D views), and edit their origins and orientations in the 2D views. | ||
| - | |||
| - | /* // Das sollte nur bei "Delete a Camera" stehen: | ||
| - | Since CaWE has always a 3D view, there has to be at least one camera in each map. */ | ||
| - | |||
| - | /* // Das sollte bei "Eine neue Camera anlegen" stehen: | ||
| - | Using more than one camera makes it possible to "save" a certain camera position and return to it later and therefore makes navigation in big maps a lot easier. */ | ||
| - | |||
| - | To activate the Camera tool, click on the related icon in the tool bar or press ''SHIFT+C''. | ||
| - | |||
| - | |||
| - | ===== Camera display in 2D views ===== | ||
| - | |||
| - | {{:mapping:cawe:editingtools:cameras_2d_tool_other.png |Cameras in a 2D view when a tool other than the Camera tool is active. The most recently used camera is highlighted.}} When a tool other than the Camera tool is active, cameras are shown with a gray dot at their origin and a gray line that indicates their viewing direction (orientation). | ||
| - | |||
| - | The most recently used (or changed) camera is highlighted (brighter shade of gray): For example, [[mapping:cawe:views#the_active_view|activating a 3D view]] highlights the related camera.<clear> | ||
| - | |||
| - | {{:mapping:cawe:editingtools:cameras_2d_tool_camera.png |Cameras in a 2D view when the Camera tool is active. The most recently used camera is highlighted.}} When the Camera tool is active, the cameras are displayed in colors so that they are easier to spot in the map. | ||
| - | |||
| - | As before, the most recently used (or changed) camera is highlighted (brighter colors).<clear> | ||
| - | |||
| - | |||
| - | ===== Creating a camera ===== | ||
| - | |||
| - | {{:mapping:cawe:editingtools:cameracreate.png }} | ||
| - | |||
| - | To create a new camera you have to hold the ''SHIFT'' key down and left click into a 2D view to define an eye position and then move the mouse to drag a viewing direction for this camera. | ||
| - | |||
| - | <clear> | ||
| - | |||
| - | {{:mapping:cawe:editingtools:cameraactiveinactive.png }} | ||
| - | |||
| - | The eye position of the camera is displayed as a cyan colored circle and the viewing angle is a red line if the camera is the active camera of the 3d view or a cyan line if the camera is currently inactive. | ||
| - | |||
| - | As the new camera is created, it becomes the active camera and the 3D view changes to this camera. | ||
| - | |||
| - | Note that created cameras are not saved and lost if you close the map. | ||
| - | |||
| - | ===== Manipulating the origin and orientation ===== | ||
| - | |||
| - | The most powerful and most convenient method to manipulate a camera is to use the controls described in section [[mapping:cawe:views#navigating_the_3d_views|Navigating the 3D views]] (in addition, the controls described there do not require the Camera tool to be active: they work always). | ||
| - | |||
| - | Sometimes however, it is worthwhile to set the origin and/or the orientation in a 2D view: | ||
| - | |||
| - | {{:mapping:cawe:editingtools:cameramoveposition.png }} | ||
| - | To change the position of the camera eye, click on the cyan colored circle and drag it to its new location. | ||
| - | |||
| - | <clear> | ||
| - | |||
| - | {{:mapping:cawe:editingtools:cameramoveangle.png }} | ||
| - | |||
| - | To change the heading of the viewing angle, click on the endpoint of the line representing the viewing angle and drag it to its new position. | ||
| - | |||
| - | <clear> | ||
| - | |||
| - | Note that you can also move the whole camera preserving its current heading by pressing the ''CTRL'' key while moving either camera position or viewing angle. | ||
| - | |||
| - | |||
| - | ===== Switching between cameras ===== | ||
| - | |||
| - | Only one camera can be active at a time and therefore define the viewport of the 3D view. To change the active camera you can use the ''PAGEUP'' and ''PAGEDOWN'' keys to cycle trough all cameras. | ||
| - | |||
| - | Another way to change the active camera is to click on the camera in a 2D view. | ||
| - | |||
| - | |||
| - | ===== Camera tool keyboard shortcuts ===== | ||
| - | |||
| - | * ''PAGEUP'' | ||
| - | * Activate next camera. | ||
| - | * ''PAGEDOWN'' | ||
| - | * Activate latter camera. | ||
| - | * ''ESC'' | ||
| - | * End camera tool and switch to Selection tool. | ||
| - | * ''SHIFT'' | ||
| - | * Clicking in 2D view creates new camera | ||
| - | * ''CTRL'' | ||
| - | * While moving the camera -> camera heading doesn't change | ||
