Class FrameFactory
java.lang.Object
 gov.nasa.worldwind.render.FrameFactory
public class FrameFactory - extends Object
Static class for drawing 2D frames.
All shapes are drawn inside a bounding rectangle whose lower left corner
is at the origin. Shapes with a leader use an offset point that indicate where the
leader triangle should point at - it usually has a negative y since the leader connects
at the bottom of the frame (at y = 0).

createShapeBuffer
public static DoubleBuffer createShapeBuffer(String shape,
double width,
double height,
int cornerRadius,
DoubleBuffer buffer)
- Create a vertex buffer for a shape with the specified width, height and corner radius. Corner radius only apply
to
SHAPE_RECTANGLE - set to zero for square corners.
- Parameters:
shape - the shape - can be one of SHAPE_RECTANGLE or SHAPE_ELLIPSE.width - the width of the overall shape.height - the height of the shape.cornerRadius - the rounded corners radius. Set to zero for square corners.buffer - the buffer to store shape vertices, or null to allocate a new buffer.
- Returns:
- the vertex buffer.
createShapeWithLeaderBuffer
public static DoubleBuffer createShapeWithLeaderBuffer(String shape,
double width,
double height,
Point leaderOffset,
double leaderGapWidth,
int cornerRadius,
DoubleBuffer buffer)
- Create a vertex buffer for a shape with the specified width, height and corner radius. The shape includes a
leader triangle pointing to a specified point. Corner radius only apply to
SHAPE_RECTANGLE
- set to zero for square corners.
- Parameters:
shape - the shape - can be one of SHAPE_RECTANGLE or SHAPE_ELLIPSE.width - the width of the overall shape.height - the height of the shape excluding the leader.leaderOffset - the coordinates of the point to which the leader leads.leaderGapWidth - the starting width of the leader shape.cornerRadius - the rounded corners radius. Set to zero for square corners.buffer - the buffer to store shape vertices, or null to allocate a new buffer.
- Returns:
- the vertex buffer.
drawBuffer
public static void drawBuffer(DrawContext dc,
int mode,
DoubleBuffer verts)
drawBuffer
public static void drawBuffer(DrawContext dc,
int mode,
int count,
DoubleBuffer verts)
- Draw a vertex buffer in a given gl mode. Vertex buffers coming from the createShapeBuffer() methods support
both
GL.GL_TRIANGLE_FAN and GL.LINE_STRIP.
- Parameters:
dc - the current DrawContext.mode - the desired drawing GL mode.count - the number of vertices to draw.verts - the vertex buffer to draw.
drawBuffer
public static void drawBuffer(DrawContext dc,
int mode,
int count,
DoubleBuffer verts,
DoubleBuffer coords)
- Draw a vertex buffer with texture coordinates in a given gl mode. Vertex buffers coming from the
createShapeBuffer() methods support both
GL.GL_TRIANGLE_FAN and GL.LINE_STRIP.
- Parameters:
dc - the current DrawContext.mode - the desired drawing GL mode.count - the number of vertices to draw.verts - the vertex buffer to draw.coords - the buffer containing the shape texture coordinates.
drawShape
public static void drawShape(DrawContext dc,
String shape,
double width,
double height,
int glMode,
int cornerRadius)
- Draw a shape with the specified width and height, gl mode and corner radius. GL mode came be one of
GL.GL_TRIANGLE_FAN and GL.LINE_STRIP. Corner radius only apply
to SHAPE_RECTANGLE - set to zero for square corners.
- Parameters:
dc - the current DrawContext.shape - the shape - can be one of SHAPE_RECTANGLE or SHAPE_ELLIPSE.width - the width of the overall shape.height - the height of the shape.glMode - the GL mode - can be one of GL.GL_TRIANGLE_FAN and GL.LINE_STRIP.cornerRadius - the rounded corners radius. Set to zero for square corners.
drawShapeWithLeader
public static void drawShapeWithLeader(DrawContext dc,
String shape,
double width,
double height,
Point leaderOffset,
double leaderGapWidth,
int glMode,
int cornerRadius)
- Draw a shape with the specified width and height, gl mode and corner radius. The shape includes a
leader triangle pointing to a specified point. GL mode came be one of
GL.GL_TRIANGLE_FAN
and GL.LINE_STRIP. Corner radius only apply to SHAPE_RECTANGLE - set to zero for square corners.
- Parameters:
dc - the current DrawContext.shape - the shape - can be one of SHAPE_RECTANGLE or SHAPE_ELLIPSE.width - the width of the overall shape.height - the height of the shape excluding the leader.leaderOffset - the coordinates of the point to which the leader leads.leaderGapWidth - the starting width of the leader shape.glMode - the GL mode - can be one of GL.GL_TRIANGLE_FAN and GL.LINE_STRIP.cornerRadius - the rounded corners radius. Set to zero for square corners.
