Detailed Description

Image manipulation.

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

Examples:

D3DGeometryItem.cpp, hlslShader.cpp, and OpenGLViewportRenderer.cpp.

Member Function Documentation

void MGeometryRequirements::addPosition

(

)

Add position to the set of required elements.

Examples:

D3DGeometryItem.cpp, hlslShader.cpp, and OpenGLViewportRenderer.cpp.

void MGeometryRequirements::addComponentId

(

)

Add component id to the set of required elements.

Examples:

hlslShader.cpp.

void MGeometryRequirements::addNormal

(

)

Add normal to the set of required elements.

Examples:

D3DGeometryItem.cpp, hlslShader.cpp, and OpenGLViewportRenderer.cpp.

void MGeometryRequirements::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:

D3DGeometryItem.cpp, hlslShader.cpp, and OpenGLViewportRenderer.cpp.

void MGeometryRequirements::addTangent

(

const MString &

name

)

Add a tangent set to the list of required elements.

Parameters:

[in]

name

the name of the uv set to add tangent data for

Examples:

D3DGeometryItem.cpp, and OpenGLViewportRenderer.cpp.

void MGeometryRequirements::addBinormal

(

const MString &

name

)

Add a binormal set to the list of required elements.

Parameters:

[in]

name

the name of the uv set to add binormal data for

Examples:

D3DGeometryItem.cpp, and OpenGLViewportRenderer.cpp.

void MGeometryRequirements::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:

D3DGeometryItem.cpp, hlslShader.cpp, and OpenGLViewportRenderer.cpp.

void MGeometryRequirements::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 MGeometryRequirements if you will ever require this information.
