Oxygen 2 - Manual
Basic setup
External Viewer: C:\program files\bohemia interactive\arma\ArmA.exe -window -buldozer -noland
- -worldCfg= - you can force using specific world config (weather settings)
- -name= - you can force specific user game settings (your ArmA instalation has separate user settings that can for example disable shadows in .../My Documents/ArmA)
- - addons... used to specify a text file which ArmA.exe will use to load project-specific extras (sunlight, clouds, and sky textures)
- -cfg= - used to specify a basic configuration file (graphics, memory, size and position of viewer window)
- -noland - option to not display any ground
- -window - option to run viewer in window instead of fullscreen
DLL Folder - path to O2 installation
Path for textures - path to work disk (usually P:\)
Source Safe Database - login to Microsoft Visual Studio Source Safe database
Terminology
Point – individual point in space
Vertex – point of intersection of two or more edges
Edge - connection between two vertices
Polygon – planar surface with any number of edges
Triangle – polygon with with three edges
Quad – polygon with four edges
Face – in O2 faces can be triangles or quads
Normal - a normal is a line which is perpendicular to the plane of a polygon. In O2 it appears as a blue line at each vertex.
Skeleton - simplified representation of a model that has moving parts
Bone – base component of a skeleton used for animation, each bone represents a moving part
Section - is created everytime when there's need on the graphics card (GPU) to change parameters. This happens when information about each object, texture and material is read from the CPU or when bones limit is exceeded. The overhead for transmitting instructions between CPU and GPU then slows down the performance of scene-drawing, which could normally draw hundrets of polygons or textures.
The time it takes to render a scene depend largely on these factors:
- number of vertices in the scene
- textures - resolution and the number of times it appears in the scene are both factors. If the texture has transparency, even more calculations need to be performed.
- number of sections in the scene
The origin point for coordinates (xyz = 0,0,0) is marked by the intersection of the red grid lines. Gridlines are spaced at 1m and all units in O2 are measured in meters.
TAB – cycle between viewports (or click in any viewport with mouse to set the active viewport)
arrow keys – scroll in viewports
CTRL+arrow keys – faster scrolling in viewports
ALT+RMB – rotate camera (only works in 3D Preview viewport)
ALT+LMB – scroll in viewports
ALT+RMB+LMB - zoom (mousewheel can also be used to zoom)
F9 – reset to 4 viewport mode (3D, front, top, left)
Space – center active viewport to pin
S – switch between selection masking modes that will be displayed Buldozer (unselected=red, selected=shining, none)
pan camera W, E, S, arrows (same as Lmouse+drag)
rotate camera A, D
rotate object NumPad_arrows (same as Rmouse+drag)
CTRL + camera movements - slower movements
Numpad_5 – reset camera and center object.
Numpad +/- - zoom
[ ] - decrease/increase speed of RTM animations
SHIFT [ ] – spomalení animace //unsure of exact function
Enter / Mousewheel cycle through animations defined in model.cfg
Back space cycle backwards through animations defined in model.cfg
change weather RWIN+U / RWIN+I
change time of day RWIN+T / RWIN+Y
toggle display of textures RWIN+X
Buldozer Menu
Start/Restart - launch or restart Buldozer viewer
Other > Attach - Attach O2 to an existing instance of Buldozer
Other > Detach - Detach O2 from Buldozer
Other > Stop - Stop updating to Buldzoer
Other > Run Script - Start a script in Buldozer
Other > Refresh Viewer - Refresh Buldozer
Hide Textures - Toggle display of textures
Hide Materials - Toggle display of materials
Hide Proxies - Toggle display of proxies
Hide Hidden Faces - Toggle display parts set as 'hidden' in O2
Multiple LODs - Toggle display of multiple LODs
Show Shadow – Toggle display of shadows (uses ShadowVolume to cast shadows on Resolution LODs)
Beware Unsupported Textures - Toggle checking for unsupported textures. Buldozer will sometimes crash because of unsupported textures, this will check if the model has links only to PAA and PAC textures. Turning this on may decrease performance.
Bring to top after update – If this option is active, buldozer will be moved on top of other windows after each update
Selection Masking > Mask Texture - Unselected faces will be masked by a texture
Selection Masking > Mask Material - Unselected faces will be masked by a material
Selection Masking > Highligt - Selected faces will be fully lit
Selection Masking > Crop - Unselected faces will be hidden
Selection Masking > Disable - No selection masking
Selection Masking > Change Masking Texture - Set path to a texture to use for masking
Selection Masking > Change Masking Material - Set path to a material to use for masking
Ground object... – Setup an object to use as a default ground surface (can be useful for viewing shadows cast by objects)
Markers... – Setup an object to be shown in place of isolated vertices (can be useful for viewing memory points)
Autocenter - Automatically center view on object
Center to Pin - Center view on pin location
Center to Selection - Center view on selection
Freeze Animation - Freeze RTM animation
Environment Editor - Opens a dialog window to adjust settings for time of day, weather, fog and lens apperture. Also allows saving current settings as presets.
