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

Viewport Navigation

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)

Buldozer navigation

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.

Pin Tool

The pin tool has many uses but basically is a moveable reference point, which can be activated and deactivated.

R – Sets cursor to 'move pin' mode. Click to place pin.

C – Centers pin to selection, or when no selection exists, centers pin to whole scene.

Space – Center active viewport to pin

Shift+C – Activate/deactivate pin. When active many functions will use the pin - such as rotate, scale, insert point.

You can use PIN mode also for simple snap.

Select LMB part of the mesh you want to snap to another. Keep the LMB pressed and move with pointer to desired snap location.
