| - | A camera is simply an eye position and a viewing direction that decides in which direction the eye is looking. | + | 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. | ||
| - | The 3D view of CaWE needs a camera to decide what part of the level geometry to display. | + | 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. |
| - | Since CaWE has always a 3D view, there has to be at least one camera in each map. | + | 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. | ||
| - | The Camera tool allows to create additional cameras, change their position and viewing direction and switch between them. | + | /* // 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. */ | ||
| - | 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. | + | /* // 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''. | To activate the Camera tool, click on the related icon in the tool bar or press ''SHIFT+C''. | ||
| - | ===== Creating a camera ===== | ||
| - | {{:mapping:cawe:editingtools:cameracreate.png }} | + | ===== Camera display in 2D views ===== |
| - | 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. | + | {{: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). |
| - | <clear> | + | The most recently used (or changed) camera is highlighted in a brighter shade of gray: For example, [[mapping:cawe:views#the_active_view|activating a 3D view]] highlights the related camera.<clear> |
| - | {{:mapping:cawe:editingtools:cameraactiveinactive.png }} | + | {{: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. |
| - | 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 before, the most recently used (or changed) camera is highlighted in brighter colors.<clear> |
| - | 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. | + | ===== Creating a camera ===== |
| - | ===== Moving a camera ===== | + | {{:mapping:cawe:editingtools:cameras_create.png |Use Shift+LMB to create a new camera.}} |
| + | To create a new camera, press and hold the ''Shift'' key, then use the left mouse button to drag a line in one of the 2D views. The starting point of the line becomes the camera origin, the line itself defines the orientation. | ||
| - | There are two ways to move a camera: | + | At this time, manually created cameras are not saved with the map; they are lost when the map is closed.<clear> |
| - | ==== Moving a camera in 2D view ==== | ||
| - | {{:mapping:cawe:editingtools:cameramoveposition.png }} | + | ===== Manipulating the origin and orientation ===== |
| - | To change the position of the camera eye, click on the cyan colored circle and drag it to its new location. | + | |
| - | <clear> | + | The most powerful and most convenient methods to manipulate a camera are 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). |
| - | {{:mapping:cawe:editingtools:cameramoveangle.png }} | + | Sometimes however, it is worthwhile to set the origin and/or the orientation in a 2D view: |
| - | 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. | + | {{:mapping:cawe:editingtools:cameras_move_pos.png |Click and drag the dot in order to move the camera origin.}} |
| + | Click and drag the dot in order to move the camera origin. | ||
| - | <clear> | + | /* Eine normale " - ..." Liste funktioniert hier nicht gut... */ |
| + | • Holding the ''Alt'' key while dragging toggles grid snapping.\\ | ||
| + | • Holding the ''Ctrl'' key moves the line as well (and thus the camera as a whole).<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. | + | {{:mapping:cawe:editingtools:cameras_move_dir.png |Click and drag the end of the line in order to change the camera orientation.}} |
| + | Click and drag the end of the line in order to change the camera orientation. | ||
| - | ==== Moving a camera in 3D view ==== | + | /* Eine normale " - ..." Liste funktioniert hier nicht gut... */ |
| + | • Holding the ''Alt'' key while dragging toggles grid snapping.\\ | ||
| + | • Holding the ''Ctrl'' key moves the dot as well (and thus the camera as a whole).<clear> | ||
| - | Moving the active camera of the 3D view doesn't require the Camera tool to be active. You can change the camera position and heading by moving in a direction with the ''WASD'' keys or changing the camera heading with the "arrow" keys (see [[mapping:cawe:views]]). | ||
| - | With an activated Camera tool however, you can control the camera position using your mouse. While holding the left mouse button down you can change the viewing angle by moving your mouse and holding the right mouse button down enables you to strafe the camera position in the direction of your mouse movement. | + | ===== Switching cameras ===== |
| - | ===== Switching between cameras ===== | + | In order to assign a 3D view (the [[mapping:cawe:views#the_active_view|active]] 3D view) another camera, use the ''Page Up'' and ''Page Down'' keys to cycle through all cameras in the map. |
| - | 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 ===== | ===== Camera tool keyboard shortcuts ===== | ||
| - | * ''PAGEUP'' | + | ^ Key ^ Action ^ |
| - | * Activate next camera. | + | | ''Page Up'' | Assign the next camera to the currently active 3D view. | |
| - | * ''PAGEDOWN'' | + | | ''Page Down'' | Assign the previous camera to the currently active 3D view. | |
| - | * Activate latter camera. | + | | ''ESC'' | Quit the camera tool and switch to the [[mapping:cawe:editingtools:selection|Selection]] tool. | |
| - | * ''ESC'' | + | | ''Shift'' | LMB-clicking and dragging in a 2D view creates new camera. | |
| - | * End camera tool and switch to Selection tool. | + | | ''Ctrl'' | Move the camera as a whole when dragging one of its handles. | |
