Mesh elements 

General options

Border angle: Select the angle criteria between faces to consider the shared edge a boundary edge, i.e. sharp edge, or not. Angles between normals of adjacent faces smaller than the criteria set will be considered a sharp edge and visualized when the mesh style 'boundaries' is selected.
Edge color: Define the color to be used to draw edges.

Point element options

Point size: Define the size of the drawn elements.
Quality: Defines the way the elements are drawn.
Quick: Points will be drawn as big dots.
Internal texture: An image is used to draw points; it's a compromise between quality and speed.
Nice: A triangle mesh, between 4 and 630 triangles big, is used to drawn each point for a nicer quality.
Nice detail: Level of detail used to draw the points in Nice mode. Higher detail level will draw more triangles for each point.

Sphere element options

Sphere size factor: factor to be applied to the spheres and circles radius to increase the size of the drawn elements.
Quality: Defines the way the elements are drawn.
Quick: Spheres and circles will be drawn as big dots.
Internal texture: An image is used to draw spheres and circles; it's a compromise between quality and speed.
Nice: A triangle mesh, between 4 and 630 triangles big, is used to drawn each sphere and circles for a nicer quality.
Nice detail: Level of detail used to draw the spheres and circles in Nice mode. Higher detail level will draw more triangles for each sphere or circle.

Line elements options

Line size: Defines the width of the lines.
Quality: Defines the way the elements are drawn.
Quick: Lines are drawn as 3-point thick lines.
Nice: Lines are drawn as long 4-sided or 8-sided prisms.
Nice detail level: Level of detail used to draw the lines in Nice mode.
