Detailed Description

Specifies the size of rasterized points. May either be set statically or by shader programs.

When the sizeMode property is set to SizeMode::Fixed, the value is set using glPointSize(), if available. When using SizeMode::Programmable, gl_PointSize must be set within shader programs, the value provided to this RenderState is ignored in that case.

Member Type Documentation

enum QPointSize::SizeMode

Constant	Value	Description
`Qt3DRender::QPointSize::Fixed`	`0`	The point size is by the QPointSize::value.
`Qt3DRender::QPointSize::Programmable`	`1`	The point size value must be set in shader
