Constant Field Values

inputs

protected List<ColladaInput> inputs

Inputs for the geometry. Inputs provide the geometry with vertices, texture coordinates, etc.

Constructor Detail

ColladaAbstractGeometry

public ColladaAbstractGeometry(String ns)

Create a new instance.

Parameters:

ns - the qualifying namespace URI. May be null to indicate no namespace qualification.

Method Detail

getCount

public int getCount()

Indicates the number of shapes (lines or triangles) in the geometry.

Returns:

The number of shapes in the geometry.

getFloatFromAccessor

protected void getFloatFromAccessor(FloatBuffer buffer,
                                    ColladaAccessor accessor,
                                    String semantic,
                                    int floatsPerVertex)

Retrieve numbers from an accessor.

Parameters:

buffer - Buffer to receive floats.

accessor - Accessor that will provide floats.

semantic - Semantic that identifiers the set of indices to use (for example, "VERTEX" or "NORMAL").

floatsPerVertex - Number of floats to read for each vertex.

getIndices

protected int[] getIndices(String semantic)

getInputs

public List<ColladaInput> getInputs()

Indicates the inputs that provide vertices, textures coordinates, etc. to the geometry.

Returns:

Inputs to the geometry.

getMaterial

public String getMaterial()

Indicates the identifier for the material applied to this geometry.

Returns:

The material applied to this geometry. May be null.

getNormalAccessor

public ColladaAccessor getNormalAccessor()

getNormals

public void getNormals(FloatBuffer buffer)

Retrieves normal vectors in this geometry.

Parameters:

buffer - Buffer to receive coordinates.

getTexCoordAccessor

public ColladaAccessor getTexCoordAccessor(String semantic)

Indicates the accessor for texture coordinates.

Parameters:

semantic - Semantic that identifies the texture coordinates. May be null, in which case the semantic "TEXCOORD" is used.

Returns:

The texture coordinates accessor, or null if the accessor cannot be resolved.

getTextureCoordinates

public void getTextureCoordinates(FloatBuffer buffer,
                                  String semantic)

Retrieves the texture coordinates of vertices in this geometry.

Parameters:

buffer - Buffer to receive coordinates.

semantic - String to identify which input holds the texture coordinates. May be null, in which case the "TEXCOORD" is used.

getVertexAccessor

public ColladaAccessor getVertexAccessor()

getVertices

public void getVertices(FloatBuffer buffer)

Retrieves the coordinates of vertices in this geometry.

Parameters:

buffer - Buffer to receive coordinates.

getVerticesPerShape

protected abstract int getVerticesPerShape()

Indicates the number of vertices per shape in the geometry.

Returns:

The number of vertices in each shape.

setField

public void setField(String keyName,
                     Object value)

Overrides:
