Detailed Description

This is a base class for the GraphicsStateGuardian class, which is itself a base class for the various GSG's for different platforms.

This class contains all the function prototypes to support the double-dispatch of GSG to geoms, transitions, etc. It lives in a separate class in its own package so we can avoid circular build dependency problems.

GraphicsStateGuardians are not actually writable to bam files, of course, but they may be passed as event parameters, so they inherit from TypedWritableReferenceCount instead of TypedReferenceCount for that convenience.

Member Function Documentation

◆ getClassType()

static TypeHandle getClassType ( )
static

◆ getDefaultGsg()

static GraphicsStateGuardianBase getDefaultGsg ( )
static

Returns a pointer to the "default" GSG.

This is typically the first GSG created in an application; in a single-window application, it will be the only GSG. This GSG is used to determine default optimization choices for loaded geometry.

The return value may be NULL if a GSG has not been created.

◆ getEffectiveIncompleteRender()

bool getEffectiveIncompleteRender ( )

◆ getGsg()

static GraphicsStateGuardianBase getGsg ( int  n)
static

Returns the nth GSG in the universe.

GSG's automatically add themselves and remove themselves from this list as they are created and destroyed.

◆ getGsgs()

list getGsgs ( )

◆ getIncompleteRender()

bool getIncompleteRender ( )

◆ getMaxTextureDimension()

int getMaxTextureDimension ( )

◆ getMaxVerticesPerArray()

int getMaxVerticesPerArray ( )

◆ getMaxVerticesPerPrimitive()

int getMaxVerticesPerPrimitive ( )

◆ getNumGsgs()

static int getNumGsgs ( )
static

Returns the total number of GSG's in the universe.

◆ getSupportedGeomRendering()

int getSupportedGeomRendering ( )

◆ getSupportsCompressedTextureFormat()

bool getSupportsCompressedTextureFormat ( int  compression_mode)

◆ getSupportsHlsl()

bool getSupportsHlsl ( )

◆ getSupportsMultisample()

bool getSupportsMultisample ( )

◆ getSupportsShadowFilter()

bool getSupportsShadowFilter ( )

◆ getSupportsTextureSrgb()

bool getSupportsTextureSrgb ( )

◆ prefersTriangleStrips()

bool prefersTriangleStrips ( )

◆ setDefaultGsg()

static setDefaultGsg ( GraphicsStateGuardianBase  default_gsg)
static

Specifies a particular GSG to use as the "default" GSG.

See get_default_gsg().
