Constructor Detail

Drawable2d

public Drawable2d(Drawable2d.Prefab shape)

Prepares a drawable from a "pre-fabricated" shape definition.

Does no EGL/GL operations, so this can be done at any time.

Method Detail

getVertexArray

public FloatBuffer getVertexArray()

Returns the array of vertices.

To avoid allocations, this returns internal state. The caller must not modify it.

getTexCoordArray

public FloatBuffer getTexCoordArray()

Returns the array of texture coordinates.

To avoid allocations, this returns internal state. The caller must not modify it.

getVertexCount

public int getVertexCount()

Returns the number of vertices stored in the vertex array.

getVertexStride

public int getVertexStride()

Returns the width, in bytes, of the data for each vertex.

getTexCoordStride

public int getTexCoordStride()

Returns the width, in bytes, of the data for each texture coordinate.

getCoordsPerVertex

public int getCoordsPerVertex()

Returns the number of position coordinates per vertex. This will be 2 or 3.

toString

public String toString()

Overrides:
