Function Documentation

void GIAPIENTRY giGetBooleanv	(	GIenum	pname,
		GIboolean *	params
	)

Retrieve boolean state value.

Parameters:

pname	state to query
params	address of variable to store value

void GIAPIENTRY giGetIntegerv	(	GIenum	pname,
		GIint *	params
	)

Retrieve integer state value.

Parameters:

pname	state to query
params	address of variable to store value

void GIAPIENTRY giGetFloatv	(	GIenum	pname,
		GIfloat *	params
	)

Retrieve floating point state value.

Parameters:

pname	state to query
params	address of variable to store value

void GIAPIENTRY giEnable

(

GIenum

pname

)

Enable feature.

Parameters:

pname

feature to enable

void GIAPIENTRY giDisable

(

GIenum

pname

)

Disable feture.

Parameters:

pname

feature to disable

GIboolean GIAPIENTRY giIsEnabled

(

GIenum

pname

)

Check if feature is enabled.

Parameters:

pname

feature to check

Return values:

GI_TRUE	feature is enabled
GI_FALSE	feature is disbaled

void GIAPIENTRY giVertexSubset	(	GIenum	subset,
		GIsizei	count,
		GIboolean	sorted,
		const GIuint *	indices
	)

Set vertex subset.

Parameters:

subset	subset to set
count	number of vertices in subset
sorted	GI_TRUE if indices sorted, GI_FALSE else
indices	indices of vertices in subset

void GIAPIENTRY giGetPointerv	(	GIenum	pname,
		GIvoid **	params
	)

Get pointer to attribute array or vertex subset.

Parameters:

pname	array to query
params	address to store pointer at

void GIAPIENTRY giAttribImage	(	GIuint	attrib,
		GIuint	image
	)

Bind image to attribute channel.

Parameters:

attrib	attribute to bind image to
image	image to bind

void GIAPIENTRY giBindAttrib	(	GIenum	semantic,
		GIuint	attrib
	)

Bind attribute to special semantic.

Parameters:

semantic	semantic to bind attribute to
attrib	attrib to use channel for semantic

void GIAPIENTRY giEnableAttribArray

(

GIuint

attrib

)

Enable attribute array.

Parameters:

attrib

attribute to enable array for

void GIAPIENTRY giDisableAttribArray

(

GIuint

attrib

)

Disable attribute array.

Parameters:

attrib

attribute to disable array for

void GIAPIENTRY giAttribPointer	(	GIuint	attrib,
		GIint	size,
		GIboolean	normalized,
		GIsizei	stride,
		GIfloat *	pointer
	)

Set attribute array to use during mesh creation and retrieval.

This function sets the pointer to the attribute data that is used to create and retrieve the mesh. This state is set for the entire context and not per mesh as the actual mesh creation and therefore use of the array is not done till either giIndexedMesh() or giNonIndexedMesh() is called.

Parameters:

attrib	attribute index to set pointer for
size	number of components per attribute
normalized	normalization flag
stride	distance between two consecutive vertices or 0 if tightly packed
pointer	pointer to attribute data

void GIAPIENTRY giGetAttribbv	(	GIuint	attrib,
		GIenum	pname,
		GIboolean *	params
	)

Retrieve boolean attribute state.

Parameters:

attrib	attribute to query
pname	state to query
params	address of variable to store value

void GIAPIENTRY giGetAttribiv	(	GIuint	attrib,
		GIenum	pname,
		GIint *	params
	)

Retrieve integer attribute state.

Parameters:

attrib	attribute to query
pname	state to query
params	address of variable to store value

void GIAPIENTRY giGetAttribfv	(	GIuint	attrib,
		GIenum	pname,
		GIfloat *	params
	)

Retrieve floating point attribute state.

Parameters:

attrib	attribute to query
pname	state to query
params	address of variable to store value

void GIAPIENTRY giGetAttribPointerv	(	GIuint	attrib,
		GIvoid **	params
	)

Get pointer to attribute array.

Parameters:

attrib	attribute to query
params	address to store pointer at

GIenum GIAPIENTRY giGetEnumValue

(

const GIchar *

name

)

Get enum value by name.

Parameters:

name	enumeration name as string

Returns:

enumeration value
