详细描述

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

当 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.

enum QPointSize:: SizeMode

This enumeration specifies values for the size mode.

常量	值	描述
`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
