详细描述

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.

成员类型

enum QPointSize::SizeMode

This enumeration specifies values for the size mode.

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

属性

sizeMode : SizeMode

Specifies the sizeMode to be used.

访问函数:

SizeMode	sizeMode() const
void	setSizeMode(SizeMode sizeMode)

Notifier signal:

void	sizeModeChanged(SizeMode sizeMode)

value : float

Specifies the point size value to be used.
