Types

DrawElements (object)

The DrawElements allows to define a simple mix of points, lines and triangles for debug drawing purposes.

Members

GeometryAttributes	attributes	Container for all attributes.
String	debugName	Name that will be printed in descriptions.
UInt32	structureVersion	Version of the geometry structure itself, excluding the GeometryAttributes content.
Boolean	computeGPUBoundingVolume	If positions are on the GPU: if true, the bounding volume is computed, else an infinite bbox is returned.
ThreadsafeMetaDataContainer	metaData	Container for holding various user data (Geometry specific), such as the BoundingBox cache data, or raycast acceleration structures and data (Octree).
Scalar	pointSize	Point size in pixels
Scalar	lineWidth	Line width in pixels

/*
** Example: DrawElements
*/

      elements.drawPoint(Vec3(0, 0, 5));
      
      // draw a couple of lines
      elements.drawLine(Vec3(0, 0, 0), Vec3(5, 0, 0));
      elements.drawLine(Vec3(0, 0, 0), Vec3(0, 5, 0));
