Method Details

add

public GeometryBuilder add(int attributeId,
 float... values)

Description copied from interface: GeometryBuilder

Adds the values for a one-component attribute. Next call to this method with the same will write to the next vertex.

Specified by:

add in interface GeometryBuilder

Parameters:

attributeId - the attribute id.

values - the component values.

Returns:

this builder.

getAttributeCount

public int getAttributeCount()

Specified by:

getAttributeCount in interface GeometryBuilder

Returns:

the attribute count.

getStrideSize

public int getStrideSize()

Specified by:

getStrideSize in interface GeometryBuilder

Returns:

the stride size.

getWidth

public int getWidth(int attributeId)

Description copied from interface: GeometryBuilder

Gets the element width for an attribute.

Specified by:

getWidth in interface GeometryBuilder

Parameters:

attributeId - the attribute id.

Returns:

the width for the provided attribute.

getOffset

public int getOffset(int attributeId)

Description copied from interface: GeometryBuilder

Gets the stride offset for an attribute.

Specified by:

getOffset in interface GeometryBuilder

Parameters:

attributeId - the attribute id.

Returns:

the offset for the provided attribute.
