Unigine::Plugins::IG::SymbolsPlane Class
Header: | #include <plugins/Unigine/IG/UnigineIG.h> |
This class represents the IG Symbols Plane interface. A symbol surface (plane) is a rectangular, two-dimensional drawing region on a virtual plane on which symbols may be drawn. Such plane is placed in 3D space relative to a particular entity or coincident with the near clipping plane of a particular view.

Перечисления (Enums)
SYMBOLS_PLANE_TYPE#
Members
int getID ( ) const#
Returns the plane identifier.Return value
Identifier of the plane.void addSymbol ( Symbol * symbol ) #
Adds the specified symbol to the plane.Arguments
- Symbol * symbol - Symbol to be added.
void setBillboard ( bool enable, bool fixed_scale ) #
Toggles on and off the plane orientation to the viewer and fixing the plane size regardless of the distance to it.Arguments
- bool enable - true to make the plane a billboard (always oriented to the viewer), false to disable orientation to the viewer.
- bool fixed_scale - true to make the billboard size unchanged regardless of its distance from the viewer, false — to disable.
bool isBillboard ( ) const#
Checks if a node is a billboard (always oriented to the viewer).Return value
true if a node is a billboard, otherwise false.bool isFixedBillboardScale ( ) const#
Checks if the billboard size is fixed relative to the viewer regardless of the distance.Return value
true if the billboard scale is fixed, otherwise false.void setPosition ( const Math::vec3 & value ) #
Sets the plane position relative to the entity, if the plane has a parent entity.Arguments
- const Math::vec3 & value - Position in the coordinate system of a parent entity.
void setRotation ( const Math::quat & rotate ) #
Sets the plane rotation relative to the parent entity. The method is not applicable to billboards.Arguments
- const Math::quat & rotate - Rotation quaternion for the plane
void setPhysicalSize ( float width, float height ) #
Sets the plane size for planes that have a parent entity.Arguments
- float width - Width of the symbols plane, in units
- float height - Height of the symbols plane, in units
vec2 getPhysicalSize ( ) const#
Returns the physical size of the symbols plane, in units.Return value
Vector containing physical size of the symbols plane (width, height), in units.void setUVSize ( float minU, float minV, float maxU, float maxV ) #
Sets the symbol surface 2D coordinate system.Arguments
- float minU - Minimum U value of the symbol surface.
- float minV - Minimum V value of the symbol surface.
- float maxU - Maximum U value of the symbol surface.
- float maxV - Maximum V value of the symbol surface.
vec4 getUVSize ( ) const#
Returns the current symbol surface 2D coordinate system.Return value
Vector containing the following values: (Minimum U, Minimum V, Maximum U, Maximum V).void setScreenSize ( float width, float height, float offsetX, float offsetY ) #
Sets the screen plane resolution and offset in pixels.Arguments
- float width - Width of the screen plane, in pixels.
- float height - Height of the screen plane, in pixels.
- float offsetX - Horizontal offset of the screen plane.
- float offsetY - Vertical offset of the screen plane.
vec4 getScreenSize ( ) const#
Returns the screen plane resolution and offset in pixels.Return value
Vector containing screen dimensions of the symbols plane (screen_width, screen_height, offset_z, offset_y), in pixels.SymbolsPlane::SYMBOLS_PLANE_TYPE getType ( ) const#
Returns the type of the symbols plane.Return value
Symbols plane type.Unigine::Vector < Symbol * > getRootSymbols ( ) const#
Returns all root symbols attached to the plane.Return value
Vector containing all root symbols attached to the plane.Unigine::Vector <Symbol *> getSymbols ( ) const#
Returns all symbols attached to the plane (roots and all their children).Return value
Vector containing all symbols attached to the plane.vec3 getPosition ( ) const#
Returns the current position of the symbols plane.Return value
Vector containing coordinates of the symbols plane position.quat getRotation ( ) const#
Returns the current rotation of the symbols plane.Return value
Quaternion representing rotation of the symbols plane position.int getPixelsPerUnitV ( ) const#
Returns the number of pixels per single vertical unit of the symbol surface.Return value
Size of the the vertical unit in pixels.Last update:
