Unigine::Plugins::IG::SymbolsPlane Class

Warning
The functionality described in this article is not available in the Community SDK edition.
You should upgrade to Sim SDK edition to use it.
Header: #include <plugins/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.

Notice
IG plugin must be loaded.

SymbolsPlane Class

Enums

SYMBOLS_PLANE_TYPE#

NameDescription
SYMBOLS_PLANE_TYPE_ENTITY = 0The symbols plane is placed relative to a particular entity.
SYMBOLS_PLANE_TYPE_VIEW = 1The symbols plane is coincident with the near clipping plane of a particular view.

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.
