## 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

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

## Property Documentation

### sizeMode : SizeMode

Specifies the sizeMode to be used.

Access functions:

SizeMode | sizeMode() const

Notifier signal:

void | sizeModeChanged(SizeMode sizeMode)

### value : float

Specifies the point size value to be used.

Access functions:

float | value() const
void | setValue(float value)

Notifier signal:

void | valueChanged(float value)

## Member Function Documentation

### QPointSize::QPointSize(Qt3DCore::QNode *parent = nullptr)

Default constructs an instance of QPointSize.
