# QPointSize Class

class Qt3DRender::QPointSize

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

- List of all members, including inherited members

## Public Types

enum | SizeMode { Fixed, Programmable }

## Properties

- sizeMode : SizeMode
- value : float

## Public Functions

Qt3DRender::QPointSize::SizeMode | sizeMode() const
float | value() const

## Public Slots

void | setSizeMode(Qt3DRender::QPointSize::SizeMode sizeMode)
void | setValue(float value)

## Signals

void | sizeModeChanged(Qt3DRender::QPointSize::SizeMode sizeMode)
void | valueChanged(float value)

## Detailed Description

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.
