          scenic.ScenePrimitives

public class ScenePrimitives
extends SceneLeaf

This scene node type is used to draw primitives. The primitives are triangles which can be colored and textured in the same way as in OpenGL and DirectX. The primitives are defined by attributes. Each attribute is an array of numbers that defines a certain property such as position, color or texture coordinate of the primitives to be drawn. Textures can also be defined. The triangles as defined by an index array (indices).

Method Detail

getAttribute

public ScenePrimitives.Attribute getAttribute(int index)

Gets the given attribute.

Parameters:

index - the index of the attribute.

Returns:

the attribute.

setAttribute

public void setAttribute(int index,
                         int size,
                         float[] data)

Sets the given attribute. The size defines the number of numbers used for a single vertice.

Parameters:

index - the index of the attribute.

size - the size of the attribute

data - the data.

setAttribute

public void setAttribute(int index,
                         int size,
                         byte[] data)

Sets the given attribute. The size defines the number of numbers used for a single vertice.

Parameters:

index - the index of the attribute.

size - the size of the attribute

data - the data.

getTexture

public ScenicImage getTexture(int index)

Gets the texture at the given index.

Parameters:

index - the index of the texture.

Returns:

the texture at the given index.

setTexture

public void setTexture(int index,
                       ScenicImage texture)

Sets the texture at the given index. Currently only one texture is allowed so the index must be 0.

Parameters:

index - the index of the texture.

texture - the texture.

getIndices

public int[] getIndices()

Gets the indices.

Returns:

the indices.

setIndices

public void setIndices(int[] indices)

Sets the indices.

Parameters:

indices - the indices.
