Class Description

This method is obsolete.

Deprecated:

Use MHWRender::MGeometryRequirements instead.

MGeometryRequirementsLegacy stores the collection of MGeometryRequirementsData arrays which describe a Maya surface, including per-component data such as UV mapping and colour.

OPENMAYA_MAJOR_NAMESPACE_OPEN MGeometryRequirementsLegacy

(

)

Default constructor.

Initialized to no requirements.

Member Function Documentation

void addPosition

(

int

dimension = 3

)

Add position to the set of required elements.

Parameters

[in]

dimension

the size of the position requirement. Valid values are 3 and 4. Default is 3.

Examples:

void addNormal

(

int

dimension = 3

)

Add normal to the set of required elements.

Parameters

[in]

dimension

the size of the normal requirement. Valid values are 3 and 4. Default is 3.

Examples:

void addTexCoord

(

const MString &

name

)

Add a texture coordinate set to the list of required elements.

Parameters

[in]

name

the name of the uv set to add

Examples:

void addTangent	(	const MString &	name,
		int	dimension = 3
	)

Add a tangent set to the list of required elements.

Parameters

[in]	name	the name of the uv set to add tangent data for
[in]	dimension	the size of the normal requirement. Valid values are 3 and 4. Default is 3.

Examples:

void addBinormal	(	const MString &	name,
		int	dimension = 3
	)

Add a binormal set to the list of required elements.

Parameters

[in]	name	the name of the uv set to add binormal data for
[in]	dimension	the size of the normal requirement. Valid values are 3 and 4. Default is 3.

Examples:

void addColor

(

const MString &

name

)

Add a color set to the list of required elements.

Parameters

[in]

name

the name of the color set to add

Examples:

void addFaceOffsets

(

)

Add face offsets to the set of required elements.

Face offsets are used internally to calculate component-indexed data such as shading group membership. Note that geometry data is cached internally, so it is important to call this method whenever you use MGeometryRequirementsLegacy if you will ever require this information.
