Detailed Description

SLText creates a mesh using a textured font from SLTexFont.

The text is passed as standard string that can contain line breaks (\n). Line breaks are only inserted if a maxWidth is defined. If the lineHeightFactor is 1.0 the minimal line spacing is used.

Constructor & Destructor Documentation

◆ SLText()

SLText::SLText ( SLstring  text,
SLTexFont font,
SLCol4f  color = SLCol4f::WHITE,
SLfloat  maxWidth = 0.0f,
SLfloat  lineHeightFactor = 1.3f 
)

The ctor sets all members and translates to the min. position.

◆ ~SLText()

SLText::~SLText ( )
inline

Member Function Documentation

◆ color()

SLCol4f SLText::color ( )
inline

◆ drawMesh()

void SLText::drawMesh ( SLSceneView sv)
inlineoverridevirtual

Draws the single mesh.

Inserts a mesh pointer in the mesh pointer vector after the specified afterM pointer.

Reimplemented from SLNode.

◆ drawText()

void SLText::drawText ( SLSceneView sv)

SLText::shapeDraw draws the text buffer objects

◆ fontHeightPX()

SLfloat SLText::fontHeightPX ( )
inline

◆ hitRec()

SLbool SLText::hitRec ( SLRay ray)
inlineoverridevirtual

Intersects the nodes meshes with the given ray. The intersection test is only done if the AABB is intersected. The ray-mesh intersection is done in the nodes object space. The rays origin and direction is therefore transformed into the object space.

Reimplemented from SLNode.

◆ length()

SLint SLText::length ( )
inline

◆ preShade()

void SLText::preShade ( SLRay ray)
inline

◆ size()

SLVec2f SLText::size ( )
inline

◆ statsRec()

void SLText::statsRec ( SLNodeStats stats)
overridevirtual

SLText::statsRec updates the statistics.

Reimplemented from SLNode.

◆ text()

SLstring SLText::text ( )
inline

◆ updateAABBRec()

SLAABBox & SLText::updateAABBRec ( SLbool  updateAlsoAABBinOS)
overridevirtual

SLText::buildAABB builds and returns the axis-aligned bounding box.

Reimplemented from SLNode.
