Detailed Description

Function support for high resolution displays.

Function Documentation

getDevicePixelRatio() [1/2]

double SoViewerElement::getDevicePixelRatio ( SoState * state )

static

Convenience method which calls the corresponding method of SoViewerProxy.

getDevicePixelRatio() [2/2]

virtual double SoViewerProxy::getDevicePixelRatio ( )

inlinevirtual

Returns the ratio between physical pixels and device-independent pixels for the viewer.

Reimplemented in SoResolutionIndependentViewerProxy.

Definition at line 221 of file SoViewerProxy.h.

GLHiDPIScale()

template<class T>

ML_OPENGL_END_NAMESPACE T GLHiDPIScale

(

T

x

)

Convenience template function to scale a value.

glLineStippleScaled()

MLOPENGL_EXPORT void glLineStippleScaled	(	GLint	factor,
		GLushort	pattern )

Sets the line stipple pattern.

The resulting pattern multiplier is guaranteed to be at least 1.

(

GLfloat

size

)

Sets the diameter of rasterized points.

The resulting point size is guaranteed to be at least 1.0.
