class Qt3DRender::QPointSizeSpecifies the size of rasterized points. May either be set statically or by shader programs. More...
| Header: | #include <QPointSize> |
| qmake: | QT += 3drender |
| Since: | Qt 5.7 |
| Instantiated By: | PointSize |
| Inherits: | Qt3DRender::QRenderState |
This class was introduced in Qt 5.7.

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.
